android - 如何捕获 ExoPlayer 的所有错误？

Question

我将 ExoPlayer 实现为我的应用程序的播放器。但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() {

    }
});

错误示例:

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;
        }
    }
