Method Detail

-

onLoadCompleted

void onLoadCompleted​([T](Loader.Callback.html "type parameter in Loader.Callback")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](Loader.Callback.html "type parameter in Loader.Callback")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](Loader.LoadErrorAction.html "class in com.google.android.exoplayer2.upstream")onLoadError​([T](Loader.Callback.html "type parameter in Loader.Callback")loadable,
                                   long elapsedRealtimeMs,
                                   long loadDurationMs,[IOException](https://developer.android.com/reference/java/io/IOException.html "class or interface in java.io")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).
