Constructors

public Builder(Context context)

Creates a builder.

Use ExoPlayer.Builder, ExoPlayer.Builder or ExoPlayer.Builder instead, if you intend to provide a custom RenderersFactory, ExtractorsFactory or DefaultMediaSourceFactory. This is to ensure that ProGuard or R8 can remove ExoPlayer's DefaultRenderersFactory, DefaultExtractorsFactory and DefaultMediaSourceFactory from the APK.

The builder uses the following default values:

RenderersFactory: DefaultRenderersFactory
TrackSelector: DefaultTrackSelector
: DefaultMediaSourceFactory
LoadControl: DefaultLoadControl
BandwidthMeter: DefaultBandwidthMeter.getSingletonInstance(Context)
LivePlaybackSpeedControl: DefaultLivePlaybackSpeedControl
: The associated with the current thread, or the of the application's main thread if the current thread doesn't have a
AnalyticsCollector: AnalyticsCollector with Clock.DEFAULT
PriorityTaskManager: null (not used)
AudioAttributes: AudioAttributes.DEFAULT, not handling audio focus
: C.WAKE_MODE_NONE
handleAudioBecomingNoisy: false
skipSilenceEnabled: false
: C.VIDEO_SCALING_MODE_DEFAULT
: C.VIDEO_CHANGE_FRAME_RATE_STRATEGY_ONLY_IF_SEAMLESS
useLazyPreparation: true
SeekParameters: SeekParameters.DEFAULT
seekBackIncrementMs: C.DEFAULT_SEEK_BACK_INCREMENT_MS
seekForwardIncrementMs: C.DEFAULT_SEEK_FORWARD_INCREMENT_MS
releaseTimeoutMs: ExoPlayer.DEFAULT_RELEASE_TIMEOUT_MS
detachSurfaceTimeoutMs: ExoPlayer.DEFAULT_DETACH_SURFACE_TIMEOUT_MS
pauseAtEndOfMediaItems: false
Clock: Clock.DEFAULT

Parameters:

context: A .

public Builder(Context context, RenderersFactory renderersFactory)
