我为我的应用程序实现了ExoPlayer作为播放器。但是我无法找到如何捕获所有ExoPlayer错误以避免应用程序崩溃。我添加了以下监听器，但它没有捕获所有错误。
我必须使用DRM，它有时会因为某些问题而崩溃，但我之前无法设置监听器，因为播放器为NULL。
player = ExoPlayerFactory.newSimpleInstance(context, trackSelector, loadControl, drmSessionManager);
player.addListener(new ExoPlayer.EventListener() {
@Override
public void onTimelineChanged(Timeline timeline, Object manifest) {
}
@Override
public void onTracksChanged(TrackGroupArray trackGroups, TrackSelectionArray trackSelections) {
}
@Override
public void onLoadingChanged(boolean isLoading) {
}
@Override
public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
}
@Override
public void onPlayerError(ExoPlaybackException error) {
//Catch here, but app still crash on some errors!
}
@Override
public void onPositionDiscontinuity() {
}
});

感谢ExoPlayer支持的反馈，这应该涵盖所有问题。
@Override
public void onPlayerError(ExoPlaybackException error) {
switch (error.type) {
case ExoPlaybackException.TYPE_SOURCE:
Log.e(TAG, "TYPE_SOURCE: " + error.getSourceException().getMessage());
break;
case ExoPlaybackException.TYPE_RENDERER:
Log.e(TAG, "TYPE_RENDERER: " + error.getRendererException().getMessage());
break;
case ExoPlaybackException.TYPE_UNEXPECTED:
Log.e(TAG, "TYPE_UNEXPECTED: " + error.getUnexpectedException().getMessage());
break;
}
}

您可能会遇到如下这样的exoplayer错误：
this.player = new SimpleExoPlayer.Builder(PlayActivity.this).build();
player.addListener(new Player.EventListener() {
@Override
public void onPlayerError(ExoPlaybackException error) {
.....
}
});

对于 Kotlin 用户，语法有点不同（我在对象声明方面遇到了困难）：
// initialize and setup exo player
player = SimpleExoPlayer.Builder(applicationContext).build()
// setup error listener
player.addListener(object : Player.EventListener {
override fun onPlayerError(error: ExoPlaybackException) {
log.debug("ExoPlayer error, ${error.sourceException.message}")
}
})
