Question

使用网络视频文件时，如何显示找不到错误？OnErrorListener无法正常工作。以下是onSurfaceTextureAvailable中的代码，当网络文件无法获取时，两者都没有反应。

try {

    mMediaPlayer = new MediaPlayer();
    mMediaPlayer.setDataSource(getApplicationContext(), Uri.parse(FILE_URL));
    mMediaPlayer.setSurface(surface);
    mMediaPlayer.setLooping(true);
    mMediaPlayer.prepareAsync();

    // Play video when the media source is ready for playback.
    mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mediaPlayer) {
            mediaPlayer.start();
            Context context = getApplicationContext();
            CharSequence text = "ok";
            int duration = Toast.LENGTH_SHORT;

            Toast toast = Toast.makeText(context, text, duration);
            toast.show();
        }
    });
    mMediaPlayer.setOnErrorListener(new MediaPlayer.OnErrorListener(){
        @Override
        public boolean onError(MediaPlayer mediaPlayer,int what,int extra){
            Context context = getApplicationContext();
            CharSequence text = "error";
            int duration = Toast.LENGTH_SHORT;

            Toast toast = Toast.makeText(context, text, duration);
            toast.show();
            return true;
        }
    });

} catch (IllegalArgumentException e) {
    Log.d(TAG, e.getMessage());
} catch (SecurityException e) {
    Log.d(TAG, e.getMessage());
} catch (IllegalStateException e) {
    Log.d(TAG, e.getMessage());
} catch (java.io.IOException e) {
    Log.d(TAG, e.getMessage());
}

你应该在将文件解析为uri之前检查文件。当文件不存在时，你可以给消息干杯。但如果视频源是网络，你可以在MediaPlayer.OnErrorListener中收到错误。
