问题描述
我将 ExoPlayer 实现为我的应用程序的播放器.但我不知道如何捕获所有 ExoPlayer 错误以避免应用程序崩溃.我添加了以下侦听器，但它没有捕获所有错误.
I implemented ExoPlayer as player for my application. But I can´t find out how to catch all ExoPlayer errors to avoid app crash. I added following listener, but it doesn´t catch all errors.
我必须使用 DRM，它有时会因某些问题而崩溃，但我之前无法设置监听器，因为播放器为 NULL.
I have to use DRM and it sometimes crash on some problem with it, but I can´t set listener before, because player is 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() {
}
});
