class TestPlayerRunHelper

Helper methods to block the calling thread until the provided ExoPlayer instance reaches a particular state.

This class has two usage modes:

  • Fluent method chaining, e.g. run(player).ignoringNonFatalErrors().untilState(STATE_ENDED).
  • Single method call, e.g. runUntilPlaybackState(player, STATE_ENDED).

New usages should prefer the fluent method chaining, and new functionality will only be added to this form. The older single methods will be kept for backwards compatibility.

Summary

Nested types

An ExoPlayer specific subclass of PlayerRunResult, giving access to conditions that only make sense for the ExoPlayer interface.

Intermediate type that allows callers to run the main Looper until certain conditions are met.

Public functions

play

java-static fun play(player: ExoPlayer!): TestPlayerRunHelper.ExoPlayerRunResult!

Entry point for a fluent "start playback and wait for condition X" assertion.

Callers can use the returned ExoPlayerRunResult to run the main Looper until certain conditions are met.

This is the same as run but ensures play is called before waiting in subsequent untilXXX(...) methods.

play

java-static fun play(player: Player!): TestPlayerRunHelper.PlayerRunResult!

Entry point for a fluent "start playback and wait for condition X" assertion.

Callers can use the returned PlayerRunResult to run the main Looper until certain conditions are met.

This is the same as run but ensures play is called before waiting in subsequent untilXXX(...) methods.

playUntilPosition

java-static fun playUntilPosition(player: ExoPlayer!, mediaItemIndex: Int, positionMs: Long): Unit

Calls play then runs tasks of the main Looper until the player 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 runUntil/playUntil... methods, custom runMainLooperUntil conditions or an explicit unblockThreadsWaitingForProgressOnCurrentLooper on the main thread.

If a checked exception occurs it will be thrown wrapped in an IllegalStateException.

New usages should prefer run and untilPosition.

Parameters
player: ExoPlayer!

The Player.
mediaItemIndex: Int

The index of the media item.
positionMs: Long

The position within the media item, in milliseconds.
Throws
java.util.concurrent.TimeoutException

If the default timeout is exceeded.

playUntilStartOfMediaItem

java-static fun playUntilStartOfMediaItem(player: ExoPlayer!, mediaItemIndex: Int): Unit

Calls play then runs tasks of the main Looper until the player 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 runUntil/playUntil... methods, custom runMainLooperUntil conditions or an explicit unblockThreadsWaitingForProgressOnCurrentLooper on the main thread.

If a checked exception occurs it will be thrown wrapped in an IllegalStateException.

New usages should prefer run and untilStartOfMediaItem.

Parameters
player: ExoPlayer!

The Player.
