Context : The context of the application |
Public methods
notifyError
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 , or TvInputManager.RECORDING_ERROR_RESOURCE_BUSY |
notifyRecordingStopped
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
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
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
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
public abstract void onRelease ()
Called when the application requests to release all the resources held by this recording session.
onResumeRecording
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
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
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
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
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
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. |
