Enclosing class:

Loader

public static interface Loader.Callback<T extends Loader.Loadable>

A callback to be notified of Loader events.

Method Summary

Modifier and Type	Method and Description
void	onLoadCanceled(T loadable, long elapsedRealtimeMs, long loadDurationMs, boolean released) Called when a load has been canceled.
void	onLoadCompleted(T loadable, long elapsedRealtimeMs, long loadDurationMs) Called when a load has completed.
Loader.LoadErrorAction	onLoadError(T loadable, long elapsedRealtimeMs, long loadDurationMs, java.io.IOException error, int errorCount) Called when a load encounters an error.

Method Detail

onLoadCompleted

void onLoadCompleted(T loadable,
                     long elapsedRealtimeMs,
                     long loadDurationMs)

Called when a load has completed.

Note: There is guaranteed to be a memory barrier between Loader.Loadable.load() exiting and this callback being called.

Parameters:

loadable - The loadable whose load has completed.

elapsedRealtimeMs - SystemClock.elapsedRealtime() when the load ended.

loadDurationMs - The duration in milliseconds of the load since Loader.startLoading(T, com.google.android.exoplayer2.upstream.Loader.Callback<T>, int) was called.

onLoadCanceled

void onLoadCanceled(T loadable,
                    long elapsedRealtimeMs,
                    long loadDurationMs,
                    boolean released)

Called when a load has been canceled.

Note: If the Loader has not been released then there is guaranteed to be a memory barrier between Loader.Loadable.load() exiting and this callback being called. If the Loader has been released then this callback may be called before Loader.Loadable.load() exits.

Parameters:

loadable - The loadable whose load has been canceled.

elapsedRealtimeMs - SystemClock.elapsedRealtime() when the load was canceled.

loadDurationMs - The duration in milliseconds of the load since Loader.startLoading(T, com.google.android.exoplayer2.upstream.Loader.Callback<T>, int) was called up to the point at which it was canceled.

released - True if the load was canceled because the Loader was released. False otherwise.

onLoadError

Loader.LoadErrorAction onLoadError(T loadable,
                                   long elapsedRealtimeMs,
                                   long loadDurationMs,
                                   java.io.IOException error,
                                   int errorCount)

Called when a load encounters an error.

Note: There is guaranteed to be a memory barrier between Loader.Loadable.load() exiting and this callback being called.

Parameters:

loadable - The loadable whose load has encountered an error.

elapsedRealtimeMs - SystemClock.elapsedRealtime() when the error occurred.

loadDurationMs - The duration in milliseconds of the load since Loader.startLoading(T, com.google.android.exoplayer2.upstream.Loader.Callback<T>, int) was called up to the point at which the error occurred.

error - The load error.

errorCount - The number of errors this load has encountered, including this one.

Returns:

The desired error handling action. One of Loader.RETRY, Loader.RETRY_RESET_ERROR_COUNT, Loader.DONT_RETRY, Loader.DONT_RETRY_FATAL or a retry action created by Loader.createRetryAction(boolean, long).
