Inherited methods

From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait(long timeoutMillis, int nanos) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait(long timeoutMillis) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait() Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public constructors

RecordingSession

Added in API level 24

public RecordingSession (Context context)

Creates a new RecordingSession.

Parameters
context	Context: The context of the application

Public methods

notifyError

Added in API level 24

public void notifyError (int error)

Informs the application that there is an error and this recording session is no longer able to start or continue recording. It may be called at any time after the recording session is created until onRelease() is called.

The application may release the current session upon receiving the error code through TvRecordingClient.RecordingCallback.onError(int). The session may call notifyRecordingStopped(android.net.Uri) if a partially recorded but still playable program is available, before calling this method.

Parameters
error	int: The error code. Should be one of the followings. TvInputManager.RECORDING_ERROR_UNKNOWN TvInputManager.RECORDING_ERROR_INSUFFICIENT_SPACE TvInputManager.RECORDING_ERROR_RESOURCE_BUSY Value is TvInputManager.RECORDING_ERROR_UNKNOWN, TvInputManager.RECORDING_ERROR_INSUFFICIENT_SPACE, or TvInputManager.RECORDING_ERROR_RESOURCE_BUSY

notifyRecordingStopped

Added in API level 24

public void notifyRecordingStopped (Uri recordedProgramUri)

Informs the application that this recording session has stopped recording and created a new data entry in the TvContract.RecordedPrograms table that describes the newly recorded program.

The recording session must call this method in response to onStopRecording(). The session may call it even before receiving a call to onStopRecording() if a partially recorded program is available when there is an error.

Parameters
recordedProgramUri	Uri: The URI of the newly recorded program.

notifyTuned

Added in API level 24

public void notifyTuned (Uri channelUri)

Informs the application that this recording session has been tuned to the given channel and is ready to start recording.

Upon receiving a call to onTune(android.net.Uri), the session is expected to tune to the passed channel and call this method to indicate that it is now available for immediate recording. When onStartRecording(android.net.Uri) is called, recording must start with minimal delay.

Parameters
channelUri	Uri: The URI of a channel.

onAppPrivateCommand

Added in API level 24

public void onAppPrivateCommand (String action, 
                Bundle data)

Processes a private command sent from the application to the TV input. This can be used to provide domain-specific features that are only known between certain TV inputs and their clients.

Parameters
action	String: Name of the command to be performed. This must be a scoped name, i.e. prefixed with a package name you own, so that different developers will not create conflicting commands. This value cannot be null.
data	Bundle: Any data to include with the command.

onPauseRecording

Added in API level 31

public void onPauseRecording (Bundle params)

Called when the application requests to pause TV program recording. Recording must pause immediately when this method is called. If the pause request cannot be fulfilled, the session must call notifyError(int).

Parameters
params	Bundle: Domain-specific data for recording request. This value cannot be null.

onRelease

Added in API level 24

public abstract void onRelease ()

Called when the application requests to release all the resources held by this recording session.

onResumeRecording

Added in API level 31

public void onResumeRecording (Bundle params)

Called when the application requests to resume TV program recording. Recording must resume immediately when this method is called. If the resume request cannot be fulfilled, the session must call notifyError(int).

Parameters
params	Bundle: Domain-specific data for recording request. This value cannot be null.

onStartRecording

Added in API level 30

public void onStartRecording (Uri programUri, 
                Bundle params)

Called when the application requests to start TV program recording. Recording must start immediately when this method is called.

The application may supply the URI for a TV program for filling in program specific data fields in the TvContract.RecordedPrograms table. A non-null programUri implies the started recording should be of that specific program, whereas null programUri does not impose such a requirement and the recording can span across multiple TV programs. In either case, the application must call TvRecordingClient.stopRecording() to stop the recording.

The session must call notifyError(int) if the start request cannot be fulfilled.

Parameters
programUri	Uri: The URI for the TV program to record, built by TvContract.buildProgramUri(long). Can be null.
params	Bundle: Domain-specific data for this tune request. Keys must be a scoped name, i.e. prefixed with a package name you own, so that different developers will not create conflicting keys. This value cannot be null.

onStartRecording

Added in API level 24

public abstract void onStartRecording (Uri programUri)

Called when the application requests to start TV program recording. Recording must start immediately when this method is called.

The application may supply the URI for a TV program for filling in program specific data fields in the TvContract.RecordedPrograms table. A non-null programUri implies the started recording should be of that specific program, whereas null programUri does not impose such a requirement and the recording can span across multiple TV programs. In either case, the application must call TvRecordingClient.stopRecording() to stop the recording.

The session must call notifyError(int) if the start request cannot be fulfilled.

Parameters
programUri	Uri: The URI for the TV program to record, built by TvContract.buildProgramUri(long). Can be null.

onStopRecording

Added in API level 24

public abstract void onStopRecording ()

Called when the application requests to stop TV program recording. Recording must stop immediately when this method is called.

The session must create a new data entry in the TvContract.RecordedPrograms table that describes the newly recorded program and call notifyRecordingStopped(android.net.Uri) with the URI to that entry. If the stop request cannot be fulfilled, the session must call notifyError(int).

onTune

Added in API level 24

public void onTune (Uri channelUri, 
                Bundle params)

Called when the application requests to tune to a given channel for TV program recording. Override this method in order to handle domain-specific features that are only known between certain TV inputs and their clients.

The application may call this method before starting or after stopping recording, but not during recording. The default implementation calls onTune(android.net.Uri).

The session must call notifyTuned(android.net.Uri) if the tune request was fulfilled, or notifyError(int) otherwise.

Parameters
channelUri	Uri: The URI of a channel.
params	Bundle: Domain-specific data for this tune request. Keys must be a scoped name, i.e. prefixed with a package name you own, so that different developers will not create conflicting keys.

onTune

Added in API level 24

public abstract void onTune (Uri channelUri)

Called when the application requests to tune to a given channel for TV program recording.

The application may call this method before starting or after stopping recording, but not during recording.

The session must call notifyTuned(android.net.Uri) if the tune request was fulfilled, or notifyError(int) otherwise.

Parameters
channelUri	Uri: The URI of a channel.
