在
MediaPlayer.setDataSource（“”）；调用 MediaPlayer.prepare() 出现 IllegalStateException 异常
现在只需把
MediaPlayer设置一个监听事件，
mMediaPlayer.reset();mMediaPlayer.setDataSource(scenicDetailResult.getSoftyuyinurl());mMediaPlayer.setOnPreparedListener(newMediaPlayer.OnPreparedListener() {@Overridepublic voidonPrepared(MediaPlayer mp) {progressBar2.setVisibility(View.INVISIBLE);bt.setVisibility(View.VISIBLE); Log.e("songwinter","is prepare finished"); setmMediaPlayer(); }});mMediaPlayer.prepareAsync();
