Public methods
pauseRecording
public void pauseRecording ()
Pause TV program recording in the current recording session. Recording is expected to pause immediately when this method is called. If recording has not yet started in the current recording session, this method does nothing.
In pause status, the application can tune during recording. To continue recording,
please call TvRecordingClient.resumeRecording() to resume instead of
TvRecordingClient.startRecording(Uri). Application can stop
the recording with TvRecordingClient.stopRecording() in recording pause status.
If the pause request cannot be fulfilled, the recording session will respond by calling
RecordingCallback.onError(int).
pauseRecording
public void pauseRecording (Bundle params)
Pause TV program recording in the current recording session. Recording is expected to pause immediately when this method is called. If recording has not yet started in the current recording session, this method does nothing.
In pause status, the application can tune during recording. To continue recording,
please call TvRecordingClient.resumeRecording() to resume instead of
TvRecordingClient.startRecording(Uri). Application can stop
the recording with TvRecordingClient.stopRecording() in recording pause status.
If the pause request cannot be fulfilled, the recording session will respond by calling
RecordingCallback.onError(int).
| Parameters | |
|---|---|
params |
Bundle: Domain-specific data for this request.
This value cannot be null. |
release
public void release ()
Releases the resources in the current recording session immediately. This may be called at any time, however if the session is already released, it does nothing.
resumeRecording
public void resumeRecording ()
Resume TV program recording only in recording pause status in the current recording session. Recording is expected to resume immediately when this method is called. If recording has not yet paused in the current recording session, this method does nothing.
When record is resumed, the recording is continue and can not re-tune. Application can
stop the recording with TvRecordingClient.stopRecording() after record resumed.
If the pause request cannot be fulfilled, the recording session will respond by calling
RecordingCallback.onError(int).
resumeRecording
public void resumeRecording (Bundle params)
Resume TV program recording only in recording pause status in the current recording session. Recording is expected to resume immediately when this method is called. If recording has not yet paused in the current recording session, this method does nothing.
When record is resumed, the recording is continues and can not re-tune. Application can
stop the recording with TvRecordingClient.stopRecording() after record resumed.
If the resume request cannot be fulfilled, the recording session will respond by calling
RecordingCallback.onError(int).
| Parameters | |
|---|---|
params |
Bundle: Domain-specific data for this request.
This value cannot be null. |
sendAppPrivateCommand
public void sendAppPrivateCommand (String action, Bundle data)
Sends a private command to the underlying TV input. This can be used to provide domain-specific features that are only known between certain clients and their TV inputs.
| Parameters | |
|---|---|
action |
String: The name of the private command to send. 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: An optional bundle to send with the command. |
setTvInteractiveAppView
public void setTvInteractiveAppView (TvInteractiveAppView view, String recordingId)
Sets the related TvInteractiveAppView instance so the interactive app service can be
notified for recording events.
| Parameters | |
|---|---|
view |
TvInteractiveAppView: The related TvInteractiveAppView instance that is linked to this TV
recording client. null to unlink the view. |
recordingId |
String: The ID of the recording which is assigned by the TV application.
null if and only if the TvInteractiveAppView parameter is
null. |
| Throws | |
|---|---|
IllegalArgumentException |
when recording ID is null and the
TvInteractiveAppView is not null; or when recording
ID is not null and the TvInteractiveAppView is
null. |
startRecording
public void startRecording (Uri programUri, Bundle params)
Starts TV program recording in the current recording session. Recording is expected to start immediately when this method is called. If the current recording session has not yet tuned to any channel, this method throws an exception.
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 recording session will respond by calling RecordingCallback.onError(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 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. |
| Throws | |
|---|---|
IllegalStateException |
If tune(String, Uri) request hasn't been handled yet or during
pause. |
startRecording
public void startRecording (Uri programUri)
Starts TV program recording in the current recording session. Recording is expected to start immediately when this method is called. If the current recording session has not yet tuned to any channel, this method throws an exception.
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 recording session will respond by calling RecordingCallback.onError(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. |
| Throws | |
|---|---|
IllegalStateException |
If tune(String, Uri) request hasn't been handled yet or during
pause. |
stopRecording
public void stopRecording ()
Stops TV program recording in the current recording session. Recording is expected to stop immediately when this method is called. If recording has not yet started in the current recording session, this method does nothing.
The recording session is expected to create a new data entry in the
TvContract.RecordedPrograms table that describes the newly
recorded program and pass the URI to that entry through to
RecordingCallback.onRecordingStopped(Uri).
If the stop request cannot be fulfilled, the recording session will respond by calling
RecordingCallback.onError(int).
tune
public void tune (String inputId, Uri channelUri, Bundle params)
Tunes to a given channel for TV program recording. The first tune request will create a new recording session for the corresponding TV input and establish a connection between the application and the session. If recording has already started in the current recording session, this method throws an exception. This can be used to provide domain-specific features that are only known between certain client and their TV inputs.
The application may call this method before starting or after stopping recording, but not during recording.
The recording session will respond by calling
RecordingCallback.onTuned(Uri) if the tune request was fulfilled, or
RecordingCallback.onError(int) otherwise.
| Parameters | |
|---|---|
inputId |
String: The ID of the TV input for the given channel. |
channelUri |
Uri: The URI of a channel. |
params |
Bundle: Domain-specific data for this tune request. Keys must be a scoped

|---|---|
IllegalStateException |
If recording is already started. |
tune
public void tune (String inputId, Uri channelUri)
Tunes to a given channel for TV program recording. The first tune request will create a new recording session for the corresponding TV input and establish a connection between the application and the session. If recording has already started in the current recording session, this method throws an exception.

The recording session will respond by calling
RecordingCallback.onTuned(Uri) if the tune request was fulfilled, or
RecordingCallback.onError(int) otherwise.
