Public methods

ignoringNonFatalErrors

public TestPlayerRunHelper.ExoPlayerRunResult ignoringNonFatalErrors()

Returns a new instance where the untilXXX(...) methods ignore non-fatal errors.

A fatal error is defined as an error that is passed to onPlayerError and results in the player transitioning to STATE_IDLE. A non-fatal error is defined as an error that is passed to any other callback (e.g. onLoadError).

untilBackgroundThreadCondition

public void untilBackgroundThreadCondition(
    Supplier<Boolean> backgroundThreadCondition
)

Runs tasks of the main Looper until the specified condition becomes true independent of a message on the main Looper.

This method is useful for cases where the condition may change outside of a main message, for example because it's checking a volatile variable or shared synchronized state that is updated on a background thread, or because checking the condition itself may cause it to become true.

This method ensures the condition is checked within artificially created main messages. When using a androidx.media3.test.utils.FakeClock, this guarantees the remainder of the test method is not executed in parallel with other background thread messages.

Parameters
Supplier<Boolean> backgroundThreadCondition

The condition to wait for.

Throws
androidx.media3.common.PlaybackException

If a playback error occurs.

java.lang.IllegalStateException

If non-fatal playback errors occur, and aren't ignored (the non-fatal exceptions will be attached with addSuppressed).

java.util.concurrent.TimeoutException

If the default timeout is exceeded.

untilPendingCommandsAreFullyHandled

public void untilPendingCommandsAreFullyHandled()

Runs tasks of the main Looper until the player completely handled all previously issued commands on the internal playback thread.

Both fatal and non-fatal errors are always ignored.

untilPlayerError

public ExoPlaybackException untilPlayerError()

Runs tasks of the main Looper until a player error occurs.

Non-fatal errors are always ignored.

untilPosition

public void untilPosition(int mediaItemIndex, long positionMs)

Runs tasks of the main Looper until playback reaches the specified position or an error occurs.

The playback thread is automatically blocked from making further progress after reaching this position and will only be unblocked by other run()/play().untilXXX(...) method chains, custom runMainLooperUntil conditions, or an explicit unblockThreadsWaitingForProgressOnCurrentLooper on the main thread.

Throws
androidx.media3.common.PlaybackException

If a playback error occurs.

java.lang.IllegalStateException

If non-fatal playback errors occur, and aren't ignored (the non-fatal exceptions will be attached with addSuppressed).

java.util.concurrent.TimeoutException

If the default timeout is exceeded.

untilSleepingForOffloadBecomes

public void untilSleepingForOffloadBecomes(boolean expectedSleepingForOffload)

Runs tasks of the main Looper until isSleepingForOffload matches the expected value, or an error occurs.

Throws
androidx.media3.common.PlaybackException

If a playback error occurs.

java.lang.IllegalStateException

If non-fatal playback errors occur, and aren't ignored (the non-fatal exceptions will be attached with addSuppressed).

java.util.concurrent.TimeoutException

If the default timeout is exceeded.

untilStartOfMediaItem

public void untilStartOfMediaItem(int mediaItemIndex)

Runs tasks of the main Looper until playback reaches the specified media item or a playback error occurs.

The playback thread is automatically blocked from making further progress after reaching the media item and will only be unblocked by other run()/play().untilXXX(...) method chains, custom runMainLooperUntil conditions, or an explicit unblockThreadsWaitingForProgressOnCurrentLooper on the main thread.

Parameters
int mediaItemIndex

The index of the media item.

Throws
androidx.media3.common.PlaybackException

If a playback error occurs.

java.lang.IllegalStateException

If non-fatal playback errors occur, and aren't ignored (the non-fatal exceptions will be attached with addSuppressed).

java.util.concurrent.TimeoutException

If the default timeout is exceeded.
