PermissionRequest

Kotlin |Java

public abstract class PermissionRequest
extends Object

java.lang.Object
↳	android.webkit.PermissionRequest

This class defines a permission request and is used when web content requests access to protected resources. The permission request related events are delivered via WebChromeClient.onPermissionRequest and WebChromeClient.onPermissionRequestCanceled. Either grant() or deny() must be called in UI thread to respond to the request. New protected resources whose names are not defined here may be requested in future versions of WebView, even when running on an older Android release. To avoid unintentionally granting requests for new permissions, you should pass the specific permissions you intend to grant to grant(), and avoid writing code like this example:

 permissionRequest.grant(permissionRequest.getResources())  // This is wrong!!!

See the WebView's release notes for information about new protected resources.

Constants

RESOURCE_AUDIO_CAPTURE

Added in API level 21

public static final String RESOURCE_AUDIO_CAPTURE

Resource belongs to audio capture device, like microphone.

Constant Value: "android.webkit.resource.AUDIO_CAPTURE"

RESOURCE_MIDI_SYSEX

Added in API level 23

public static final String RESOURCE_MIDI_SYSEX

Resource will allow sysex messages to be sent to or received from MIDI devices. These messages are privileged operations, e.g. modifying sound libraries and sampling data, or even updating the MIDI device's firmware. Permission may be requested for this resource in API levels 21 and above, if the Android device has been updated to WebView 45 or above.

Constant Value: "android.webkit.resource.MIDI_SYSEX"

RESOURCE_PROTECTED_MEDIA_ID

Added in API level 21

public static final String RESOURCE_PROTECTED_MEDIA_ID

Resource belongs to protected media identifier. After the user grants this resource, the origin can use EME APIs to generate the license requests.

Constant Value: "android.webkit.resource.PROTECTED_MEDIA_ID"

RESOURCE_VIDEO_CAPTURE

Added in API level 21

public static final String RESOURCE_VIDEO_CAPTURE

Resource belongs to video capture device, like camera.

Constant Value: "android.webkit.resource.VIDEO_CAPTURE"
