MediaStore

class MediaStore
kotlin.Any
   ↳ android.provider.MediaStore

The contract between the media provider and applications. Contains definitions for the supported URIs and columns.

The media provider provides an indexed collection of common media types, such as Audio, Video, and Images, from any attached storage devices. Each collection is organized based on the primary MIME type of the underlying content; for example, image/* content is indexed under Images. The Files collection provides a broad view across all collections, and does not filter by MIME type.

ACTION_IMAGE_CAPTURE

Added in API level 3
static val ACTION_IMAGE_CAPTURE: String

Standard Intent action that can be sent to have the camera application capture an image and return it.

The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. This is useful for applications that only need a small image. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT. As of android.os.Build.VERSION_CODES#LOLLIPOP, this uri can also be supplied through android.content.Intent#setClipData(ClipData). If using this approach, you still must supply the uri through the EXTRA_OUTPUT field for compatibility with old applications. If you don't set a ClipData, it will be copied there for you when calling Context.startActivity(Intent).

Regardless of whether or not EXTRA_OUTPUT is present, when an image is captured via this intent, android.hardware.Camera#ACTION_NEW_PICTURE won't be broadcasted.

Note: if you app targets M and above and declares as using the android.Manifest.permission#CAMERA permission which is not granted, then attempting to use this action will result in a .

Value: "android.media.action.IMAGE_CAPTURE"

ACTION_IMAGE_CAPTURE_SECURE

Added in API level 17
static val ACTION_IMAGE_CAPTURE_SECURE: String

Intent action that can be sent to have the camera application capture an image and return it when the device is secured (e.g. with a pin, password, pattern, or face unlock). Applications responding to this intent must not expose any personal content like existing photos or videos on the device. The applications should be careful not to share any photo or video with other applications or Internet. The activity should use android.app.Activity#setShowWhenLocked to display on top of the lock screen while secured. There is no activity stack when this flag is used, so launching more than one activity is strongly discouraged.

The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. This is useful for applications that only need a small image. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT. As of android.os.Build.VERSION_CODES#LOLLIPOP, this uri can also be supplied through android.content.Intent#setClipData(ClipData). If using this approach, you still must supply the uri through the EXTRA_OUTPUT field for compatibility with old applications. If you don't set a ClipData, it will be copied there for you when calling Context.startActivity(Intent).

Regardless of whether or not EXTRA_OUTPUT is present, when an image is captured via this intent, android.hardware.Camera#ACTION_NEW_PICTURE won't be broadcasted.

Value: "android.media.action.IMAGE_CAPTURE_SECURE"

static val ACTION_MOTION_PHOTO_CAPTURE_SECURE: String

Intent action that can be sent to have the camera application capture a motion photo and return it when the device is secured (e.g. with a pin, password, pattern, or face unlock). Applications responding to this intent must not expose any personal content like existing photos or videos on the device. The applications should be careful not to share any photo or video with other applications or Internet. The activity should use android.app.Activity#setShowWhenLocked to display on top of the lock screen while secured.

Value: "android.provider.action.MOTION_PHOTO_CAPTURE_SECURE"

ACTION_PICK_IMAGES

Added in API level 33
Also in R Extensions 2
static val ACTION_PICK_IMAGES: String

Activity Action: Allow the user to select images or videos provided by system and return it. This is different than Intent.ACTION_PICK and Intent.ACTION_GET_CONTENT in that

  • the data for this action is provided by the system
  • this action is only used for picking images and videos
  • caller gets read access to user picked items even without storage permissions

Callers can optionally specify MIME type (such as image/* or video/*), resulting in a range of content selection that the caller is interested in. The optional MIME type can be requested with Intent.setType(String).

If the caller needs multiple returned items (or caller wants to allow multiple selection), then it can specify MediaStore.EXTRA_PICK_IMAGES_MAX to indicate this.

When the caller requests multiple selection, the value of android.provider.MediaStore#EXTRA_PICK_IMAGES_MAX must be a positive integer greater than 1 and less than or equal to MediaStore.getPickImagesMaxLimit, otherwise Activity.RESULT_CANCELED is returned. Use MediaStore.EXTRA_PICK_IMAGES_IN_ORDER in multiple selection mode to allow the user to pick images in order.

Callers may use Intent.EXTRA_LOCAL_ONLY to limit content selection to local data.

For system stability, it is preferred to open the URIs obtained from using this action by calling MediaStore.openFileDescriptor(ContentResolver, Uri, String, CancellationSignal), MediaStore.openAssetFileDescriptor(ContentResolver, Uri, String, CancellationSignal) or MediaStore.openTypedAssetFileDescriptor(ContentResolver, Uri, String, Bundle, CancellationSignal) instead of ContentResolver open APIs.

Output: MediaStore content URI(s) of the item(s) that was picked. Unlike other MediaStore URIs, these are referred to as 'picker' URIs and expose a limited set of read-only operations. Specifically, picker URIs can only be opened for read and queried for columns in PickerMediaColumns.

Before this API, apps could use Intent.ACTION_GET_CONTENT. However, ACTION_PICK_IMAGES is now the recommended option for images and videos, since it offers a better user experience.

Value: "android.provider.action.PICK_IMAGES"

ACTION_PICK_IMAGES_SETTINGS

Added in API level 33
Also in R Extensions 3
static val ACTION_PICK_IMAGES_SETTINGS: String

Activity Action: Launch settings controlling images or videos selection with ACTION_PICK_IMAGES. The settings page allows a user to change the enabled CloudMediaProvider on the device and other media selection configurations.

Value: "android.provider.action.PICK_IMAGES_SETTINGS"

ACTION_REVIEW

Added in API level 29
static val ACTION_REVIEW: String

Standard action that can be sent to review the given media file.

The launched application is expected to provide a large-scale view of the given media file, while allowing the user to quickly access other recently captured media files.

Input: Intent.getData is URI of the primary media item to initially display.

Value: "android.provider.action.REVIEW"

ACTION_REVIEW_SECURE

Added in API level 29
static val ACTION_REVIEW_SECURE: String

Standard action that can be sent to review the given media file when the device is secured (e.g. with a pin, password, pattern, or face unlock). The applications should be careful not to share any media with other applications or Internet. The activity should use Activity.setShowWhenLocked to display on top of the lock screen while secured. There is no activity stack when this flag is used, so launching more than one activity is strongly discouraged.

The launched application is expected to provide a large-scale view of the given primary media file, while only allowing the user to quickly access other media from an explicit secondary list.

Input: Intent.getData is URI of the primary media item to initially display. Intent.getClipData is the limited list of secondary media items that the user is allowed to review. If Intent.getClipData is undefined, then no other media access should be allowed.

Value: "android.provider.action.REVIEW_SECURE"

ACTION_VIDEO_CAPTURE

Added in API level 3
static val ACTION_VIDEO_CAPTURE: String

Standard Intent action that can be sent to have the camera application capture a video and return it.

The caller may pass in an extra EXTRA_VIDEO_QUALITY to control the video quality.

The caller may pass in an extra EXTRA_OUTPUT to control where the video is written.

Note: if you app targets M and above and declares as using the android.Manifest.permission#CAMERA permission which is not granted, then atempting to use this action will result in a .

Value: "android.media.action.VIDEO_CAPTURE"

AUTHORITY

Added in API level 1
static val AUTHORITY: String

The authority for the media provider

Value: "media"

EXTRA_ACCEPT_ORIGINAL_MEDIA_FORMAT

Added in API level 31
static val EXTRA_ACCEPT_ORIGINAL_MEDIA_FORMAT: String

Specify that the caller wants to receive the original media format without transcoding. Caution: using this flag can cause app compatibility issues whenever Android adds support for new media formats. Clients should instead specify their supported media capabilities explicitly in their manifest or with the EXTRA_MEDIA_CAPABILITIES open flag. This option is useful for apps that don't attempt to parse the actual byte contents of media files, such as playback using MediaPlayer or for off-device backup. Note that the android.Manifest.permission#ACCESS_MEDIA_LOCATION permission will still be required to avoid sensitive metadata redaction, similar to setRequireOriginal(android.net.Uri). Note that this flag overrides any explicitly declared media_capabilities.xml or ApplicationMediaCapabilities extras specified in the same open request.

This option can be added to the opts Bundle in various ContentResolver open methods.

Value: "android.provider.extra.ACCEPT_ORIGINAL_MEDIA_FORMAT"

EXTRA_BRIGHTNESS

Added in API level 29

If the capabilities specified matches the format of the original file, the app will receive the original file, otherwise, it will get transcoded to a default supported format. This flag takes higher precedence over the applications declared media_capabilities.xml and is useful for apps that want to have more granular control over their supported media capabilities.

This option can be added to the opts Bundle in various ContentResolver open methods.

Value: "android.provider.extra.MEDIA_CAPABILITIES"

EXTRA_MEDIA_CAPABILITIES_UID

Added in API level 31

Added in R Extensions 15
static val EXTRA_PICKER_PRE_SELECTION_URIS: String

The name of an optional intent-extra used to specify URIs for pre-selection in photo picker opened with MediaStore.ACTION_PICK_IMAGES in multi-select mode.

Only MediaStore content URI(s) of the item(s) received as a result of MediaStore.ACTION_PICK_IMAGES action are accepted. The value of this intent-extra should be an ArrayList of type URIs. Default value is null. Maximum number of URIs that can be accepted is limited by the value passed in MediaStore.EXTRA_PICK_IMAGES_MAX as part of the MediaStore.ACTION_PICK_IMAGES intent. In case the count of input URIs is greater than the limit then IllegalArgumentException is thrown.

The provided list will be checked for permissions and authority. Any URI that is inaccessible, doesn't match the current authorities(local or cloud) or is invalid will be filtered out.

The items corresponding to the URIs will appear selected when the photo picker is opened. In the case of MediaStore.EXTRA_PICK_IMAGES_IN_ORDER the chronological order of the input list will be used for ordered selection of the pre-selected items.

This is not a mechanism to revoke permissions for items, i.e. de-selection of a pre-selected item by the user will not result in revocation of the grant.

The accent color will be used for various primary elements in the PhotoPicker view. All other colors will be set based on android material guidelines.

The value of this intent extra should be a long color value. The alpha component of the given color is not taken into account while setting the accent color. We assume full color opacity. Only colors with luminance(can also be understood as brightness) greater than 0.05 and less than 0.9 are permitted. Luminance of a color is determined using: luminance = Color.luminance(color) where color is the input accent color to be set. Check Color docs for more details on color luminance and long color values. In case the luminance of the input color is unacceptable, picker colors will be set based on the colors of the device android theme. In case of an invalid input color value i.e. the input color cannot be parsed, IllegalArgumentException is thrown.

Value: "android.provider.extra.PICK_IMAGES_ACCENT_COLOR"

An intent to perform a search for music media and automatically play content from the result when possible. This can be fired, for example, by the result of a voice recognition command to listen to music.

This intent always includes the android.provider.MediaStore#EXTRA_MEDIA_FOCUS and android.app.SearchManager#QUERY extras. The android.provider.MediaStore#EXTRA_MEDIA_FOCUS extra determines the search mode, and the value of the android.app.SearchManager#QUERY extra depends on the search mode. For more information about the search modes for this intent, see Play music based on a search query in Common Intents.

This intent makes the most sense for apps that can support large-scale search of music, such as services connected to an online database of music which can be streamed and played on the device.

Value: "android.media.action.MEDIA_PLAY_FROM_SEARCH"
Added in API level 3
static val INTENT_ACTION_MEDIA_SEARCH: String

Activity Action: Perform a search for media. Contains at least the android.app.SearchManager#QUERY extra. May also contain any combination of the following extras: EXTRA_MEDIA_ARTIST, EXTRA_MEDIA_ALBUM, EXTRA_MEDIA_TITLE, EXTRA_MEDIA_FOCUS

Value: "android.intent.action.MEDIA_SEARCH"

Added in API level 17
static val INTENT_ACTION_STILL_IMAGE_CAMERA_SECURE: String

The name of the Intent action used to launch a camera in still image mode for use when the device is secured (e.g. with a pin, password, pattern, or face unlock). Applications responding to this intent must not expose any personal content like existing photos or videos on the device. The applications should be careful not to share any photo or video with other applications or internet. The activity should use android.app.Activity#setShowWhenLocked to display on top of the lock screen while secured. There is no activity stack when this flag is used, so launching more than one activity is strongly discouraged.

Value: "android.media.action.STILL_IMAGE_CAMERA_SECURE"

INTENT_ACTION_TEXT_OPEN_FROM_SEARCH

Added in API level 17
static val INTENT_ACTION_TEXT_OPEN_FROM_SEARCH: String

An intent to perform a search for readable media and automatically play content from the result when possible. This can be fired, for example, by the result of a voice recognition command to read a book or magazine.

Contains the android.app.SearchManager#QUERY extra, which is a string that can contain any type of unstructured text search, like the name of a book or magazine, an author a genre, a publisher, or any combination of these.

Because this intent includes an open-ended unstructured search string, it makes the most sense for apps that can support large-scale search of text media, such as services connected to an online database of books and/or magazines which can be read on the device.

Value: "android.media.action.TEXT_OPEN_FROM_SEARCH"

INTENT_ACTION_VIDEO_CAMERA

Public methods

canManageMedia

Added in API level 31
static fun canManageMedia(context: Context): Boolean

Returns whether the calling app is granted android.Manifest.permission#MANAGE_MEDIA or not.

Declaring the permission android.Manifest.permission#MANAGE_MEDIA isn't enough to gain the access.

To request access, use android.provider.Settings#ACTION_REQUEST_MANAGE_MEDIA.

Parameters
context Context: the request context This value cannot be null.
Return
Boolean true, the calling app is granted the permission. Otherwise, false

createDeleteRequest

Added in API level 30
static fun createDeleteRequest(
    resolver: ContentResolver, 
    uris: MutableCollection<Uri!>
): PendingIntent

Create a PendingIntent that will prompt the user to permanently delete the requested media items. When the user approves this request, android.content.ContentResolver#delete will be called on these items.

This call only generates the request for a prompt; to display the prompt, call android.app.Activity#startIntentSenderForResult with PendingIntent.getIntentSender(). You can then determine if the user granted your request by testing for Activity.RESULT_OK in android.app.Activity#onActivityResult. The requested operation will have completely finished before this activity result is delivered.

The displayed prompt will reflect all the media items you're requesting, including those for which you already hold write access. If you want to determine if you already hold write access before requesting access, use Context.checkUriPermission(Uri, int, int, int) with Intent.FLAG_GRANT_WRITE_URI_PERMISSION.

Parameters
resolver ContentResolver: Used to connect with MediaStore.AUTHORITY. Typically this value is Context.getContentResolver(), but if you need more explicit lifecycle controls, you can obtain a ContentProviderClient and wrap it using ContentResolver.wrap(ContentProviderClient). This value cannot be null.
uris MutableCollection<Uri!>: The set of media items to include in this request. Each item must be hosted by MediaStore.AUTHORITY and must reference a specific media item by BaseColumns._ID. This value cannot be null.
Return
PendingIntent This value cannot be null.

This call only generates the request for a prompt; to display the prompt, call android.app.Activity#startIntentSenderForResult with PendingIntent.getIntentSender(). You can then determine if the user granted your request by testing for Activity.RESULT_OK in android.app.Activity#onActivityResult. The requested operation will have completely finished before this activity result is delivered.

The displayed prompt will reflect all the media items you're requesting, including those for which you already hold write access. If you want to determine if you already hold write access before requesting access, use Context.checkUriPermission(Uri, int, int, int) with Intent.FLAG_GRANT_WRITE_URI_PERMISSION.

Parameters
resolver ContentResolver: Used to connect with MediaStore.AUTHORITY. Typically this value is Context.getContentResolver(), but if you need more explicit lifecycle controls, you can obtain a ContentProviderClient and wrap it using ContentResolver.wrap(ContentProviderClient). This value cannot be null.
uris MutableCollection<Uri!>: The set of media items to include in this request. Each item must be hosted by MediaStore.AUTHORITY and must reference a specific media item by BaseColumns._ID. This value cannot be null.
value Boolean: The MediaColumns.IS_FAVORITE value to apply.
Return
PendingIntent This value cannot be null.

createTrashRequest

Added in API level 30
static fun createTrashRequest(
    resolver: ContentResolver, 
    uris: MutableCollection<Uri!>, 
    value: Boolean
): PendingIntent

Create a PendingIntent that will prompt the user to trash the requested media items. When the user approves this request, MediaColumns.IS_TRASHED is set on these items.

This call only generates the request for a prompt; to display the prompt, call android.app.Activity#startIntentSenderForResult with PendingIntent.getIntentSender(). You can then determine if the user granted your request by testing for Activity.RESULT_OK in android.app.Activity#onActivityResult. The requested operation will have completely finished before this activity result is delivered.

The displayed prompt will reflect all the media items you're requesting, including those for which you already hold write access. If you want to determine if you already hold write access before requesting access, use Context.checkUriPermission(Uri, int, int, int) with Intent.FLAG_GRANT_WRITE_URI_PERMISSION.

Parameters
resolver ContentResolver: Used to connect with MediaStore.AUTHORITY. Typically this value is Context.getContentResolver(), but if you need more explicit lifecycle controls, you can obtain a ContentProviderClient and wrap it using ContentResolver.wrap(ContentProviderClient). This value cannot be null.
uris MutableCollection<Uri!>: The set of media items to include in this request. Each item must be hosted by MediaStore.AUTHORITY and must reference a specific media item by BaseColumns._ID. This value cannot be null.

createWriteRequest

Added in API level 30
static fun createWriteRequest(
    resolver: ContentResolver, 
    uris: MutableCollection<Uri!>
): PendingIntent

Create a PendingIntent that will prompt the user to grant your app write access for the requested media items.

This call only generates the request for a prompt; to display the prompt, call android.app.Activity#startIntentSenderForResult with PendingIntent.getIntentSender(). You can then determine if the user granted your request by testing for Activity.RESULT_OK in android.app.Activity#onActivityResult. The requested operation will have completely finished before this activity result is delivered.

Permissions granted through this mechanism are tied to the lifecycle of the Activity that requests them. If you need to retain longer-term access for background actions, you can place items into a ClipData or Intent which can then be passed to Context.startService or android.app.job.JobInfo.Builder#setClipData. Be sure to include any relevant access modes you want to retain, such as Intent.FLAG_GRANT_WRITE_URI_PERMISSION.

The displayed prompt will reflect all the media items you're requesting, including those for which you already hold write access. If you want to determine if you already hold write access before requesting access, use Context.checkUriPermission(Uri, int, int, int) with Intent.FLAG_GRANT_WRITE_URI_PERMISSION.

For security and performance reasons this method does not support Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION or Intent.FLAG_GRANT_PREFIX_URI_PERMISSION.

The write access granted through this request is general-purpose, and once obtained you can directly android.content.ContentResolver#update columns like MediaColumns.IS_FAVORITE, MediaColumns.IS_TRASHED, or android.content.ContentResolver#delete.

Parameters
resolver ContentResolver: Used to connect with MediaStore.AUTHORITY. Typically this value is Context.getContentResolver(), but if you need more explicit lifecycle controls, you can obtain a ContentProviderClient and wrap it using ContentResolver.wrap(ContentProviderClient). This value cannot be null.
uris MutableCollection<Uri!>: The set of media items to include in this request. Each item must be hosted by MediaStore.AUTHORITY and must reference a specific media item by BaseColumns._ID. This value cannot be null.
Return
PendingIntent This value cannot be null.

getDocumentUri

Added in API level 26
static fun getDocumentUri(
    context: Context, 
    mediaUri: Uri
): Uri?

Return a DocumentsProvider Uri that is an equivalent to the given MediaStore Uri.

This allows apps with Storage Access Framework permissions to convert between MediaStore and DocumentsProvider Uris that refer to the same underlying item. Note that this method doesn't grant any new permissions; callers must already hold permissions obtained with Intent.ACTION_OPEN_DOCUMENT or related APIs.

Parameters
mediaUri Uri: The MediaStore Uri to convert. This value cannot be null.
context Context: This value cannot be null.
Return
Uri? An equivalent DocumentsProvider Uri. Returns null if no equivalent was found.

getExternalVolumeNames

Added in API level 29
static fun getExternalVolumeNames(context: Context): MutableSet<String!>

Return list of all specific volume names that make up VOLUME_EXTERNAL. This includes a unique volume name for each shared storage device that is currently attached, which typically includes MediaStore.VOLUME_EXTERNAL_PRIMARY.

Each specific volume name can be passed to APIs like MediaStore.Images.Media.getContentUri(String) to interact with media on that storage device.

Parameters
context Context: This value cannot be null.
Return
MutableSet<String!> This value cannot be null.

getGeneration

Added in API level 30
Also in R Extensions 1
static fun getGeneration(
    context: Context, 
    volumeName: String
): Long

Return the latest generation value for the given volume.

Generation numbers are useful for apps that are attempting to quickly identify exactly which media items have been added or changed since a previous point in time. Generation numbers are monotonically increasing over time, and can be safely arithmetically compared.

Detecting media changes using generation numbers is more robust than using MediaColumns.DATE_ADDED or MediaColumns.DATE_MODIFIED, since those values may change in unexpected ways when apps use File.setLastModified(long) or when the system clock is set incorrectly.

Note that before comparing these detailed generation values, you should first confirm that the overall version hasn't changed by checking MediaStore.getVersion(Context, String), since that indicates when a more radical change has occurred. If the overall version changes, you should assume that generation numbers have been reset and perform a full synchronization pass.

Parameters
volumeName String: specific volume to obtain an generation value for. Must be one of the values returned from getExternalVolumeNames(android.content.Context). This value cannot be null.
context Context: This value cannot be null.

getMediaScannerUri

Added in API level 1
static fun getMediaScannerUri(): Uri!

Uri for querying the state of the media scanner.

getMediaUri

Added in API level 29
static fun getMediaUri(
    context: Context, 
    documentUri: Uri
): Uri?

Return a MediaStore Uri that is an equivalent to the given DocumentsProvider Uri. This only supports ExternalStorageProvider and MediaDocumentsProvider Uris.

This allows apps with Storage Access Framework permissions to convert between MediaStore and DocumentsProvider Uris that refer to the same underlying item. Note that this method doesn't grant any new permissions, but it grants the same access to the Media Store Uri as the caller has to the given DocumentsProvider Uri; callers must already hold permissions for documentUri obtained with Intent.ACTION_OPEN_DOCUMENT or related APIs.

Parameters
documentUri Uri: The DocumentsProvider Uri to convert. This value cannot be null.
context Context: This value cannot be null.
Return
Uri? An equivalent MediaStore Uri. Returns null if no equivalent was found.

getOriginalMediaFormatFileDescriptor

Added in API level 31
static fun getOriginalMediaFormatFileDescriptor(
    context: Context, 
    fileDescriptor: ParcelFileDescriptor
): ParcelFileDescriptor

Returns ParcelFileDescriptor representing the original media file format for fileDescriptor.

Media files may get transcoded based on an application's media capabilities requirements. However, in various cases, when the application needs access to the original media file, or doesn't attempt to parse the actual byte contents of media files, such as playback using MediaPlayer or for off-device backup, this method can be useful.

This method is applicable only for media files managed by MediaStore.

The method returns the original file descriptor with the same permission that the caller has for the input file descriptor.

Parameters
context Context: This value cannot be null.
fileDescriptor ParcelFileDescriptor: This value cannot be null.
Return
ParcelFileDescriptor This value cannot be null.
Exceptions
java.io.IOException if the given ParcelFileDescriptor could not be converted

getPickImagesMaxLimit

Added in API level 33
Also in R Extensions 2
static fun getPickImagesMaxLimit(): Int

static fun getRecentExternalVolumeNames(context: Context): MutableSet<String!>

Return list of all recent volume names that have been part of VOLUME_EXTERNAL.

These volume names are not currently mounted, but they're likely to reappear in the future, so apps are encouraged to preserve any indexed metadata related to these volumes to optimize user experiences.

Each specific volume name can be passed to APIs like MediaStore.Images.Media.getContentUri(String) to interact with media on that storage device.

Parameters
context Context: This value cannot be null.
Return
MutableSet<String!> This value cannot be null.

getRedactedUri

Added in API level 31
static fun getRedactedUri(
    resolver: ContentResolver, 
    uri: Uri
): Uri?

Returns an EXIF redacted version of uri i.e. a Uri with metadata such as location, GPS datestamp etc. redacted from the EXIF headers.

A redacted Uri can be used to share a file with another application wherein exposing sensitive information in EXIF headers is not desirable. Note: 1. Redacted uris cannot be granted write access and can neither be used to perform any kind of write operations. 2. To get a redacted uri the caller must hold read permission to uri.

Parameters
resolver ContentResolver: The ContentResolver used to connect with MediaStore.AUTHORITY. Typically this value is gotten from Context.getContentResolver() This value cannot be null.
uri Uri: the Uri Uri to convert This value cannot be null.

A redacted Uri can be used to share a file with another application wherein exposing sensitive information in EXIF headers is not desirable. Note: 1. Order of the returned uris follow the order of the uris. 2. Redacted uris cannot be granted write access and can neither be used to perform any kind of write operations. 3. To get a redacted uri the caller must hold read permission to its corresponding uri.

Parameters
resolver ContentResolver: The ContentResolver used to connect with MediaStore.AUTHORITY. Typically this value is gotten from Context.getContentResolver() This value cannot be null.
uris MutableList<Uri!>: the list of Uri Uri to convert This value cannot be null.
Return

resolver ContentResolver: The ContentResolver used to connect with MediaStore.AUTHORITY. Typically this value is Context.getContentResolver(). This value cannot be null.
uid Int: The uid to be checked if it is the current system gallery.
packageName String: The package name to be checked if it is the current system gallery. This value cannot be null.

isSupportedCloudMediaProviderAuthority

Added in API level 33
Also in R Extensions 3
static fun isSupportedCloudMediaProviderAuthority(
    resolver: ContentResolver, 
    authority: String
): Boolean

Returns true if and only if the caller with authority is a supported CloudMediaProvider. More specifically, false is also returned if the calling uid doesn't match the uid of the authority.

Parameters
resolver ContentResolver: This value cannot be null.
authority String: This value cannot be null.

notifyCloudMediaChangedEvent

Added in API level 33
Also in R Extensions 3
static fun notifyCloudMediaChangedEvent(
    resolver: ContentResolver, 
    authority: String, 
    currentMediaCollectionId: String
): Unit

Notifies the OS about a cloud media event requiring a full or incremental media collection sync for the currently enabled cloud provider, authority. The OS will schedule the sync in the background and will attempt to batch frequent notifications into a single sync event. If the caller is not the currently enabled cloud provider as returned by isCurrentCloudMediaProviderAuthority(android.content.ContentResolver,java.lang.String), the request will be unsuccessful.

Parameters
resolver ContentResolver: This value cannot be null.
authority String: This value cannot be null.
currentMediaCollectionId String: This value cannot be null.
Exceptions
java.lang.SecurityException if the request was unsuccessful.

openAssetFileDescriptor

Added in R Extensions 15
static fun openAssetFileDescriptor(
    resolver: ContentResolver, 
    uri: Uri, 
    mode: String, 
    cancellationSignal: CancellationSignal?
): AssetFileDescriptor?

Works exactly the same as ContentResolver.openAssetFileDescriptor(Uri, String, CancellationSignal), but only works for Uri whose scheme is ContentResolver.SCHEME_CONTENT and its authority is MediaStore.AUTHORITY.

This API is preferred over ContentResolver.openAssetFileDescriptor(Uri, String, CancellationSignal) when opening media Uri for ensuring system stability especially when opening URIs returned as a result of using MediaStore.ACTION_PICK_IMAGES

Parameters
resolver ContentResolver: The ContentResolver used to connect with MediaStore.AUTHORITY. Typically this value is gotten from Context.getContentResolver() This value cannot be null.
uri Uri: The desired URI to open. This value cannot be null.
mode String: The string representation of the file mode. Can be "r", "w", "wt", "wa", "rw" or "rwt". Please note the exact implementation of these may differ for each Provider implementation - for example, "w" may or may not truncate. This value cannot be null.
cancellationSignal CancellationSignal?: This value may be null.
Return
AssetFileDescriptor? a new ParcelFileDescriptor pointing to the file or null if the provider recently crashed. You own this descriptor and are responsible for closing it when done.
Exceptions
java.io.FileNotFoundException if no file exists under the URI.
java.lang.IllegalArgumentException if The URI is not for MediaStore.AUTHORITY

openFileDescriptor

Added in R Extensions 15
static fun openFileDescriptor(
    resolver: ContentResolver, 
    uri: Uri, 
    mode: String, 
    cancellationSignal: CancellationSignal?
): ParcelFileDescriptor?

Works exactly the same as ContentResolver.openFileDescriptor(Uri, String, CancellationSignal), but only works for Uri whose scheme is ContentResolver.SCHEME_CONTENT and its authority is MediaStore.AUTHORITY.

This API is preferred over ContentResolver.openFileDescriptor(Uri, String, CancellationSignal) when opening media Uri for ensuring system stability especially when opening URIs returned as a result of using MediaStore.ACTION_PICK_IMAGES

Parameters
resolver ContentResolver: The ContentResolver used to connect with MediaStore.AUTHORITY. Typically this value is gotten from Context.getContentResolver() This value cannot be null.
uri Uri: The desired URI to open. This value cannot be null.
mode String: The string representation of the file mode. Can be "r", "w", "wt", "wa", "rw" or "rwt". Please note the exact implementation of these may differ for each Provider implementation - for example, "w" may or may not truncate. This value cannot be null.
cancellationSignal CancellationSignal?: A signal to cancel the operation in progress, or null if none. If the operation is canceled, then OperationCanceledException will be thrown.
Return
ParcelFileDescriptor? a new ParcelFileDescriptor pointing to the file or null if the provider recently crashed. You own this descriptor and are responsible for closing it when done.
Exceptions
java.io.FileNotFoundException if no file exists under the URI.
java.lang.IllegalArgumentException if The URI is not for MediaStore.AUTHORITY

openTypedAssetFileDescriptor

Added in R Extensions 15
static fun openTypedAssetFileDescriptor(
    resolver: ContentResolver, 
    uri: Uri, 
    mimeType: String, 
    opts: Bundle?, 
    cancellationSignal: CancellationSignal?
): AssetFileDescriptor?

Works exactly the same as ContentResolver.openTypedAssetFileDescriptor(Uri, String, Bundle, CancellationSignal), but only works for Uri whose scheme is ContentResolver.SCHEME_CONTENT and its authority is MediaStore.AUTHORITY.

This API is preferred over ContentResolver.openTypedAssetFileDescriptor(Uri, String, Bundle, CancellationSignal) when opening media Uri for ensuring system stability especially when opening URIs returned as a result of using MediaStore.ACTION_PICK_IMAGES

Parameters
resolver ContentResolver: The ContentResolver used to connect with MediaStore.AUTHORITY. Typically this value is gotten from Context.getContentResolver() This value cannot be null.
uri Uri: The desired URI to open. This value cannot be null.
mimeType String: The desired MIME type of the returned data. This can be a pattern such as */*, which will allow the content provider to select a type, though there is no way for you to determine what type it is returning. This value cannot be null.
opts Bundle?: Additional provider-dependent options. This value may be null.
cancellationSignal CancellationSignal?: This value may be null.
Return
AssetFileDescriptor? a new ParcelFileDescriptor from which you can read the data stream from the provider or null if the provider recently crashed. Note that this may be a pipe, meaning you can't seek in it. The only seek you should do is if the AssetFileDescriptor contains an offset, to move to that offset before reading. You own this descriptor and are responsible for closing it when done.
Exceptions
java.io.FileNotFoundException if no data of the desired type exists under the URI.
java.lang.IllegalArgumentException if The URI is not for MediaStore.AUTHORITY

setIncludePending

Added in API level 29
Deprecated in API level 30
static fun setIncludePending(uri: Uri): Uri

Deprecated: consider migrating to QUERY_ARG_MATCH_PENDING which is more expressive.

Update the given Uri to also include any pending media items from calls such as ContentResolver.query(Uri, String[], Bundle, CancellationSignal). By default no pending items are returned.

Parameters
uri Uri: This value cannot be null.
Return
Uri This value cannot be null.

setRequireOriginal

Added in API level 29
static fun setRequireOriginal(uri: Uri): Uri

Update the given Uri to indicate that the caller requires the original file contents when calling ContentResolver.openFileDescriptor(Uri, String).

This can be useful when the caller wants to ensure they're backing up the exact bytes of the underlying media, without any Exif redaction being performed.

If the original file contents cannot be provided, a UnsupportedOperationException will be thrown when the returned Uri is used, such as when the caller doesn't hold android.Manifest.permission#ACCESS_MEDIA_LOCATION.

Parameters
uri Uri: This value cannot be null.
Return
Uri This value cannot be null.

Properties

AUTHORITY_URI

Added in API level 29
static val AUTHORITY_URI: Uri

A content:// style uri to the authority for the media provider
