Playing an audio file with ExoPlayer a few seconds after calling .prepare()
I have a feature in my app that has to play one short audio file multiple times, and using the code below I'm preparing ExoPlayer to play the audio:
SimpleExoPlayer player;
private void readyExoPlayerRaw(int rawSound) {
player = ExoPlayerFactory.newSimpleInstance(this, new DefaultTrackSelector());
DataSpec dataSpec = new DataSpec(RawResourceDataSource.buildRawResourceUri(rawSound));
final RawResourceDataSource rawResourceDataSource = new RawResourceDataSource(this);
try {
rawResourceDataSource.open(dataSpec);
} catch (RawResourceDataSource.RawResourceDataSourceException e) {
e.printStackTrace();
}
MediaSource audioSource =
new ExtractorMediaSource.Factory(
new DefaultDataSourceFactory(this, "appName"))
.createMediaSource(rawResourceDataSource.getUri());
player.prepare(audioSource);
//player.setPlayWhenReady(true);
}
The problem is that the sound plays fine when I uncomment the last line (//player.setPlayWhenReady(true);), but since I'm playing the sound a few seconds after I run this method, this line of code wont work! I think because it waits for a callback from previous line (.prepare(...)) and when it's ready, it will then play. So I thought that maybe I should call start() or something like that on the player, but there's just no such method.
So I'm stuck with calling .prepare() each time I want to play the audio, but since it plays in very short intervals, calling prepare() causes an unsuitable delay.
So am I missing something? How can I play a prepared MediaSource without preparing it again?

I think you're on the right track!
setPlayWhenReady is how you pause and play the audio, but it'll only actually play when it's "ready" aka done preparing.
So you should only have to call your readyExoPlayerRaw once probably in onResume or onCreate. Then at the end of that method you can set playWhenReady(false) so that it doesn't start playing until you tell it to.
Then when you want to play the sound, do something like the following:
private void playSound() {
// Go to the beginning of the audio (in case it has played before)
player.seekTo(0);
// Tell it to play the sound
exoPlayer. setPlayWhenReady(true);
}
Let me know if that works.
