abstract Unit	`registerCallback(callback: InCallService.VideoCall.Callback!)` Registers a callback to receive commands and state changes for video calls.
abstract Unit	`registerCallback(callback: InCallService.VideoCall.Callback!, handler: Handler!)` Registers a callback to receive commands and state changes for video calls.
abstract Unit	`requestCallDataUsage()` Issues a request to the `Connection.VideoProvider` to retrieve the cumulative data usage for the video component of the current call (in bytes).
abstract Unit	`requestCameraCapabilities()` Issues a request to the `Connection.VideoProvider` to retrieve the capabilities of the current camera.
abstract Unit	`sendSessionModifyRequest(requestProfile: VideoProfile!)` Issues a request to modify the properties of the current video session.
abstract Unit	`sendSessionModifyResponse(responseProfile: VideoProfile!)` Provides a response to a request to change the current call video session properties.
abstract Unit	`setCamera(cameraId: String!)` Sets the camera to be used for the outgoing video.
abstract Unit	`setDeviceOrientation(rotation: Int)` Sets the device orientation, in degrees.
abstract Unit	`setDisplaySurface(surface: Surface!)` Sets the surface to be used for displaying the video received from the remote device.
abstract Unit	`setPauseImage(uri: Uri!)` Provides the `Connection.VideoProvider` with the `Uri` of an image to be displayed to the peer device when the video signal is paused.
abstract Unit	`setPreviewSurface(surface: Surface!)` Sets the surface to be used for displaying a preview of what the user's camera is currently capturing.
abstract Unit	`setZoom(value: Float)` Sets the camera zoom ratio.
abstract Unit	`unregisterCallback(callback: InCallService.VideoCall.Callback!)` Clears the video call callback set via #registerCallback.

VideoCall

VideoCall()

Public methods

registerCallback

Added in API level 23

abstract fun registerCallback(callback: InCallService.VideoCall.Callback!): Unit

Registers a callback to receive commands and state changes for video calls.

Parameters
`callback`	InCallService.VideoCall.Callback!: The video call callback.

registerCallback

Added in API level 23

abstract fun registerCallback(
    callback: InCallService.VideoCall.Callback!, 
    handler: Handler!
): Unit

Registers a callback to receive commands and state changes for video calls.

Parameters
`callback`	InCallService.VideoCall.Callback!: The video call callback.
`handler`	Handler!: A handler which commands and status changes will be delivered to.

requestCallDataUsage

Added in API level 23

abstract fun requestCallDataUsage(): Unit

Issues a request to the Connection.VideoProvider to retrieve the cumulative data usage for the video component of the current call (in bytes). Data usage is reported to the caller via VideoCall.Callback#onCallDataUsageChanged.

Handled by Connection.VideoProvider#onRequestConnectionDataUsage().

requestCameraCapabilities

Added in API level 23

abstract fun requestCameraCapabilities(): Unit

Issues a request to the Connection.VideoProvider to retrieve the capabilities of the current camera. The current camera is selected using VideoCall#setCamera(String).

Camera capabilities are reported to the caller via VideoCall.Callback#onCameraCapabilitiesChanged(VideoProfile.CameraCapabilities).

Handled by Connection.VideoProvider#onRequestCameraCapabilities().

sendSessionModifyRequest

Added in API level 23

abstract fun sendSessionModifyRequest(requestProfile: VideoProfile!): Unit

Issues a request to modify the properties of the current video session.

Example scenarios include: requesting an audio-only call to be upgraded to a bi-directional video call, turning on or off the user's camera, sending a pause signal when the InCallService is no longer the foreground application.

Handled by Connection.VideoProvider#onSendSessionModifyRequest(VideoProfile, VideoProfile).

Parameters
`requestProfile`	VideoProfile!: The requested call video properties.

sendSessionModifyResponse

Added in API level 23

abstract fun sendSessionModifyResponse(responseProfile: VideoProfile!): Unit

Provides a response to a request to change the current call video session properties. This should be called in response to a request the InCallService has received via VideoCall.Callback#onSessionModifyRequestReceived.

Handled by Connection.VideoProvider#onSendSessionModifyResponse(VideoProfile).

Parameters
`responseProfile`	VideoProfile!: The response call video properties.

setCamera

Added in API level 23

abstract fun setCamera(cameraId: String!): Unit

Sets the camera to be used for the outgoing video.

Handled by Connection.VideoProvider#onSetCamera(String).

Parameters
`cameraId`	String!: The id of the camera (use ids as reported by `CameraManager#getCameraIdList()`).

setDeviceOrientation

Added in API level 23

abstract fun setDeviceOrientation(rotation: Int): Unit

Sets the device orientation, in degrees. Assumes that a standard portrait orientation of the device is 0 degrees.

Handled by Connection.VideoProvider#onSetDeviceOrientation(int).

Parameters
`rotation`	Int: The device orientation, in degrees.

setDisplaySurface

Added in API level 23

abstract fun setDisplaySurface(surface: Surface!): Unit

Sets the surface to be used for displaying the video received from the remote device.

Handled by Connection.VideoProvider#onSetDisplaySurface(Surface).

Parameters
`surface`	Surface!: The `Surface`.

setPauseImage

Added in API level 23

abstract fun setPauseImage(uri: Uri!): Unit

Provides the Connection.VideoProvider with the Uri of an image to be displayed to the peer device when the video signal is paused.

Handled by Connection.VideoProvider#onSetPauseImage(Uri).

Parameters
`uri`	Uri!: URI of image to display.

setPreviewSurface

Added in API level 23

abstract fun setPreviewSurface(surface: Surface!): Unit

Sets the surface to be used for displaying a preview of what the user's camera is currently capturing. When video transmission is enabled, this is the video signal which is sent to the remote device.

Handled by Connection.VideoProvider#onSetPreviewSurface(Surface).

Parameters
`surface`	Surface!: The `Surface`.

setZoom

Added in API level 23

abstract fun setZoom(value: Float): Unit

Sets the camera zoom ratio.

Handled by Connection.VideoProvider#onSetZoom(float).

Parameters
`value`	Float: The camera zoom ratio; for the current camera, should be a value in the range defined by `android.hardware.camera2.CameraCharacteristics#CONTROL_ZOOM_RATIO_RANGE`.

unregisterCallback

Added in API level 23

abstract fun unregisterCallback(callback: InCallService.VideoCall.Callback!): Unit

Clears the video call callback set via #registerCallback.

Parameters
`callback`	InCallService.VideoCall.Callback!: The video call callback to clear.
