bindIsolatedService

Added in API level 29
Deprecated in API level 24
public boolean bindIsolatedService (Intent service, 
                int flags, 
                String instanceName, 
                Executor executor, 
                ServiceConnection conn)

Variation of bindService(Intent, BindServiceFlags, Executor, ServiceConnection) that, in the specific case of isolated services, allows the caller to generate multiple instances of a service from a single component declaration. In other words, you can use this to bind to a service that has specified R.attr.isolatedProcess and, in addition to the existing behavior of running in an isolated process, you can also through the arguments here have the system bring up multiple concurrent processes hosting their own instances of that service. The instanceName you provide here identifies the different instances, and you can use updateServiceGroup(android.content.ServiceConnection, int, int) to tell the system how it should manage each of these instances.

Parameters
service Intent: Identifies the service to connect to. The Intent must specify an explicit component name. This value cannot be null.

flags int: Operation options for the binding as per ContextWrapper.bindService(Intent, BindServiceFlags, Executor, ServiceConnection).

instanceName String: Unique identifier for the service instance. Each unique name here will result in a different service instance being created. Identifiers must only contain ASCII letters, digits, underscores, and periods. This value cannot be null.

executor Executor: Callbacks on ServiceConnection will be called on executor. Must use same instance for the same instance of ServiceConnection. This value cannot be null. Callback and listener events are dispatched through this Executor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use Context.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread.

conn ServiceConnection: Receives information as the service is started and stopped. This must be a valid ServiceConnection object; it must not be null.

Returns
boolean Returns success of binding as per bindService(Intent, BindServiceFlags, Executor, ServiceConnection).

bindService

Added in API level 29
Deprecated in API level 24
public boolean bindService (Intent service, 
                int flags, 
                Executor executor, 
                ServiceConnection conn)

Same as bindService(Intent, ServiceConnection, int) with executor to control ServiceConnection callbacks.

This method only accepts a 32 bits flag, to pass in a 64 bits flag, call bindService(android.content.Intent, android.content.Context.BindServiceFlags, java.util.concurrent.Executor, android.content.ServiceConnection) instead.

Parameters
service Intent: This value cannot be null.

flags int: Value is either 0 or a combination of Context.BIND_AUTO_CREATE, Context.BIND_DEBUG_UNBIND, Context.BIND_NOT_FOREGROUND, Context.BIND_ABOVE_CLIENT, Context.BIND_ALLOW_OOM_MANAGEMENT, Context.BIND_WAIVE_PRIORITY, Context.BIND_IMPORTANT, Context.BIND_ADJUST_WITH_ACTIVITY, Context.BIND_NOT_PERCEPTIBLE, Context.BIND_ALLOW_ACTIVITY_STARTS, Context.BIND_INCLUDE_CAPABILITIES, Context.BIND_SHARED_ISOLATED_PROCESS, Context.BIND_PACKAGE_ISOLATED_PROCESS, and Context.BIND_EXTERNAL_SERVICE

executor Executor: Callbacks on ServiceConnection will be called on executor. Must use same instance for the same instance of ServiceConnection. This value cannot be null. Callback and listener events are dispatched through this Executor, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use Context.getMainExecutor(). Otherwise, provide an Executor that dispatches to an appropriate thread.

conn ServiceConnection: This value cannot be null.

Returns
boolean The result of the binding as described in bindService(Intent, ServiceConnection, int).

bindService

Added in API level 1
public boolean bindService (Intent service, 
                ServiceConnection conn, 
                int flags)

Connects to an application service, creating it if needed. This defines a dependency between your application and the service. The given conn will receive the service object when it is created and be told if it dies and restarts. The service will be considered required by the system only for as long as the calling context exists. For example, if this Context is an Activity that is stopped, the service will not be required to continue running until the Activity is resumed.

If the service does not support binding, it may return null from its onBind() method. If it does, then the ServiceConnection's onNullBinding() method will be invoked instead of onServiceConnected().

Note: This method cannot be called from a BroadcastReceiver component. A pattern you can use to communicate from a BroadcastReceiver to a Service is to call startService(Intent) with the arguments containing the command to be sent, with the service calling its Service.stopSelf(int) method when done executing that command. See the API demo App/Service/Service Start Arguments Controller for an illustration of this. It is okay, however, to use this method from a BroadcastReceiver that has been registered with registerReceiver(BroadcastReceiver, IntentFilter), since the lifetime of this BroadcastReceiver is tied to another object (the one that registered it).

This method only accepts a int type flag, to pass in a long type flag, call bindService(android.content.Intent, android.content.ServiceConnection, android.content.Context.BindServiceFlags) instead.

Parameters
service Intent: Identifies the service to connect to. The Intent must specify an explicit component name. This value cannot be null.

conn ServiceConnection: Receives information as the service is started and stopped. This must be a valid ServiceConnection object; it must not be null.

flags int: Operation options for the binding. Can be:

Returns
boolean true if the system is in the process of bringing up a service that your client has permission to bind to; false if the system couldn't find the service or if your client doesn't have permission to bind to it. Regardless of the return value, you should later call unbindService(ServiceConnection) to release the connection.

checkUriPermission

Added in API level 1
public int checkUriPermission (Uri uri, 
                int pid, 
                int uid, 
                int modeFlags)

Determine whether a particular process and uid has been granted permission to access a specific URI. This only checks for permissions that have been explicitly granted -- if the given process/uid has more general access to the URI's content provider then this check will always fail.

Parameters
uri Uri: The uri that is being checked.

pid int: The process ID being checked against. Must be > 0.

uid int: The UID being checked against. A uid of 0 is the root user, which will pass every permission check.

modeFlags int: The access modes to check. Value is either 0 or a combination of Intent.FLAG_GRANT_READ_URI_PERMISSION, and Intent.FLAG_GRANT_WRITE_URI_PERMISSION

Returns
int PackageManager.PERMISSION_GRANTED if the given pid/uid is allowed to access that uri, or PackageManager.PERMISSION_DENIED if it is not. Value is PackageManager.PERMISSION_GRANTED, or PackageManager.PERMISSION_DENIED

checkUriPermission

Added in API level 1
public int checkUriPermission (Uri uri, 
                String readPermission, 
                String writePermission, 
                int pid, 
                int uid, 
                int modeFlags)

Check both a Uri and normal permission. This allows you to perform both checkPermission(String, int, int) and checkUriPermission(Uri, int, int, int) in one call.

Parameters
uri Uri: This value may be null.

readPermission String: This value may be null.

writePermission String: This value may be null.

pid int: The process ID being checked against. Must be > 0.

uid int: The UID being checked against. A uid of 0 is the root user, which will pass every permission check.

modeFlags int: The access modes to check. Value is either 0 or a combination of Intent.FLAG_GRANT_READ_URI_PERMISSION, and Intent.FLAG_GRANT_WRITE_URI_PERMISSION

Returns
int PackageManager.PERMISSION_GRANTED if the caller is allowed to access that uri or holds one of the given permissions, or PackageManager.PERMISSION_DENIED if it is not. Value is PackageManager.PERMISSION_GRANTED, or PackageManager.PERMISSION_DENIED

getAndClearBroadcastIntents

Added in API level 1
public List<Intent> getAndClearBroadcastIntents ()

Deprecated in API level 24
public AttributionSource getAttributionSource ()

Returns
AttributionSource This value cannot be null.

getContentResolver

Added in API level 1

ContentResolver

getFilesDir

Added in API level 1
public File getFilesDir ()

Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

The returned path may change over time if the calling app is moved to an adopted storage device, so only relative paths should be persisted.

No additional permissions are required for the calling app to read or write files under the returned path.

Returns
File The path of the directory holding application files.

getSystemService

Added in API level 1
public Object getSystemService (String name)

Return the handle to a system-level service by name. The class of the returned object varies by the requested name. Currently available names are:

WINDOW_SERVICE ("window")
The top-level window manager in which you can place custom windows. The returned object is a WindowManager. Must only be obtained from a visual context such as Activity or a Context created with createWindowContext(int, android.os.Bundle), which are adjusted to the configuration and visual bounds of an area on screen.

Note: System services obtained via this API may be closely associated with the Context in which they are obtained from. In general, do not share the service objects between various different contexts (Activities, Applications, Services, Providers, etc.)

Note: Instant apps, for which PackageManager.isInstantApp() returns true, don't have access to the following system services: DEVICE_POLICY_SERVICE, FINGERPRINT_SERVICE, KEYGUARD_SERVICE, SHORTCUT_SERVICE, USB_SERVICE, WALLPAPER_SERVICE, WIFI_P2P_SERVICE, WIFI_SERVICE, WIFI_AWARE_SERVICE. For these services this method will return null. Generally, if you are running as an instant app you should always check whether the result of this method is null.

Note: When implementing this method, keep in mind that new services can be added on newer Android releases, so if you're looking for just the explicit names mentioned above, make sure to return null when you don't recognize the name — if you throw a RuntimeException exception instead, your app might break on new Android releases.

Value is Context.POWER_SERVICE, Context.WINDOW_SERVICE, Context.LAYOUT_INFLATER_SERVICE, Context.ACCOUNT_SERVICE, Context.ACTIVITY_SERVICE, Context.ALARM_SERVICE, Context.NOTIFICATION_SERVICE, Context.ACCESSIBILITY_SERVICE, Context.CAPTIONING_SERVICE, Context.KEYGUARD_SERVICE, Context.LOCATION_SERVICE, Context.HEALTHCONNECT_SERVICE, Context.SEARCH_SERVICE, Context.SENSOR_SERVICE, android.content.Context.SENSOR_PRIVACY_SERVICE, Context.STORAGE_SERVICE, Context.STORAGE_STATS_SERVICE, Context.WALLPAPER_SERVICE, Context.VIBRATOR_MANAGER_SERVICE, Context.VIBRATOR_SERVICE, android.content.Context.THREAD_NETWORK_SERVICE, Context.CONNECTIVITY_SERVICE, android.content.Context.PAC_PROXY_SERVICE, android.content.Context.VCN_MANAGEMENT_SERVICE, Context.IPSEC_SERVICE, Context.VPN_MANAGEMENT_SERVICE, android.content.Context.TEST_NETWORK_SERVICE, Context.NETWORK_STATS_SERVICE, Context.WIFI_SERVICE, Context.WIFI_AWARE_SERVICE, Context.WIFI_P2P_SERVICE, android.content.Context.WIFI_SCANNING_SERVICE, Context.WIFI_RTT_RANGING_SERVICE, Context.NSD_SERVICE, Context.AUDIO_SERVICE, android.content.Context.AUDIO_DEVICE_VOLUME_SERVICE, android.content.Context.AUTH_SERVICE, Context.FINGERPRINT_SERVICE, Context.BIOMETRIC_SERVICE, android.content.Context.AUTHENTICATION_POLICY_SERVICE, Context.MEDIA_ROUTER_SERVICE, Context.TELEPHONY_SERVICE, Context.TELEPHONY_SUBSCRIPTION_SERVICE, Context.CARRIER_CONFIG_SERVICE, Context.EUICC_SERVICE, Context.TELECOM_SERVICE, Context.CLIPBOARD_SERVICE, Context.INPUT_METHOD_SERVICE, Context.TEXT_SERVICES_MANAGER_SERVICE, Context.TEXT_CLASSIFICATION_SERVICE, Context.APPWIDGET_SERVICE, android.content.Context.REBOOT_READINESS_SERVICE, android.content.Context.ROLLBACK_SERVICE, Context.DROPBOX_SERVICE, Context.DEVICE_POLICY_SERVICE, Context.UI_MODE_SERVICE, Context.DOWNLOAD_SERVICE, Context.NFC_SERVICE, Context.BLUETOOTH_SERVICE, Context.USB_SERVICE, Context.LAUNCHER_APPS_SERVICE, Context.INPUT_SERVICE, Context.DISPLAY_SERVICE, Context.USER_SERVICE, Context.RESTRICTIONS_SERVICE, Context.APP_OPS_SERVICE, Context.ROLE_SERVICE, Context.CAMERA_SERVICE, Context.PRINT_SERVICE, Context.CONSUMER_IR_SERVICE, Context.TV_INTERACTIVE_APP_SERVICE, Context.TV_INPUT_SERVICE, Context.USAGE_STATS_SERVICE, Context.MEDIA_SESSION_SERVICE, Context.MEDIA_COMMUNICATION_SERVICE, Context.BATTERY_SERVICE, Context.JOB_SCHEDULER_SERVICE, Context.PERSISTENT_DATA_BLOCK_SERVICE, Context.MEDIA_PROJECTION_SERVICE, Context.MIDI_SERVICE, android.content.Context.RADIO_SERVICE, Context.HARDWARE_PROPERTIES_SERVICE, Context.SHORTCUT_SERVICE, Context.SYSTEM_HEALTH_SERVICE, Context.COMPANION_DEVICE_SERVICE, Context.VIRTUAL_DEVICE_SERVICE, Context.CROSS_PROFILE_APPS_SERVICE, android.content.Context.PERMISSION_SERVICE, android.content.Context.LIGHTS_SERVICE, Context.LOCALE_SERVICE, android.content.Context.UWB_SERVICE, Context.MEDIA_METRICS_SERVICE, Context.DISPLAY_HASH_SERVICE, Context.CREDENTIAL_SERVICE, Context.DEVICE_LOCK_SERVICE, android.content.Context.VIRTUALIZATION_SERVICE, Context.GRAMMATICAL_INFLECTION_SERVICE, Context.SECURITY_STATE_SERVICE, Context.CONTACT_KEYS_SERVICE, android.content.Context.RANGING_SERVICE, android.content.Context.MEDIA_QUALITY_SERVICE, or android.content.Context.ADVANCED_PROTECTION_SERVICE This value cannot be null.

Returns
Object The service or null if the name does not exist.

registerReceiver

Added in API level 1
public Intent registerReceiver (BroadcastReceiver receiver, 
                IntentFilter filter)

Register a BroadcastReceiver to be run in the main activity thread. The receiver will be called with any broadcast Intent that matches filter, in the main application thread.

The system may broadcast Intents that are "sticky" -- these stay around after the broadcast has finished, to be sent to any later registrations. If your IntentFilter matches one of these sticky Intents, that Intent will be returned by this function and sent to your receiver as if it had just been broadcast.

There may be multiple sticky Intents that match filter, in which case each of these will be sent to receiver. In this case, only one of these can be returned directly by the function; which of these that is returned is arbitrarily decided by the system.

If you know the Intent your are registering for is sticky, you can supply null for your receiver. In this case, no receiver is registered -- the function simply returns the sticky Intent that matches filter. In the case of multiple matches, the same rules as described above apply.

See BroadcastReceiver for more information on Intent broadcasts.

As of Build.VERSION_CODES.UPSIDE_DOWN_CAKE, the system can place context-registered broadcasts in a queue while the app is in the cached state. When the app leaves the cached state, such as returning to the foreground, the system delivers any queued broadcasts. Multiple instances of certain broadcasts might be merged into one broadcast.

As of Build.VERSION_CODES.ICE_CREAM_SANDWICH, receivers registered with this method will correctly respect the Intent.setPackage(String) specified for an Intent being broadcast. Prior to that, it would be ignored and delivered to all matching registered receivers. Be careful if using this for security.

For apps targeting Build.VERSION_CODES.UPSIDE_DOWN_CAKE, either RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED must be specified if the receiver is not being registered for system broadcasts or a SecurityException will be thrown. See registerReceiver(android.content.BroadcastReceiver, android.content.IntentFilter, int) to register a receiver with flags.

Note: this method cannot be called from a BroadcastReceiver component; that is, from a BroadcastReceiver that is declared in an application's manifest. It is okay, however, to call this method from another BroadcastReceiver that has itself been registered at run time with registerReceiver(BroadcastReceiver, IntentFilter), since the lifetime of such a registered BroadcastReceiver is tied to the object that registered it.

Parameters
receiver BroadcastReceiver: This value may be null.

filter IntentFilter: Selects the Intent broadcasts to be received.

Returns
Intent The first sticky intent found that matches filter, or null if there are none.

sendBroadcast

Added in API level 1
public void sendBroadcast (Intent intent)

Broadcast the given intent to all interested BroadcastReceivers. This call is asynchronous; it returns immediately, and you will continue executing while the receivers are run. No results are propagated from receivers and receivers can not abort the broadcast. If you want to allow receivers to propagate results or abort the broadcast, you must send an ordered broadcast using sendOrderedBroadcast(android.content.Intent, java.lang.String).

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
intent Intent: The Intent to broadcast; all receivers matching this Intent will receive the broadcast.

sendOrderedBroadcast

Added in API level 1
public void sendOrderedBroadcast (Intent intent, 
                String receiverPermission)

Broadcast the given intent to all interested BroadcastReceivers, delivering them one at a time to allow more preferred receivers to consume the broadcast before it is delivered to less preferred receivers. This call is asynchronous; it returns immediately, and you will continue executing while the receivers are run.

See BroadcastReceiver for more information on Intent broadcasts.

Parameters
intent Intent: The Intent to broadcast; all receivers matching this Intent will receive the broadcast.

receiverPermission String: This value may be null.

unregisterReceiver

Added in API level 1
public void unregisterReceiver (BroadcastReceiver receiver)

Unregister a previously registered BroadcastReceiver. All filters that have been registered for this BroadcastReceiver will be removed.

Parameters
receiver BroadcastReceiver: The BroadcastReceiver to unregister.
