android：媒体播放器 – 在状态8中调用暂停

我在我的应用程序中使用媒体播放器发出一些简短的声音.虽然我的应用程序中没有发现任何问题/崩溃,但我可以看到以下一些错误消息..请帮我解决此问题.

03-23 22:53:16.229: E/MediaPlayer(19185): pause called in state 8

您可以使用简单的if-check来处理暂停.试试这个：

MediaPlayer mp = MediaPlayer.create(this, Uri.parse(Environment.getExternalStorageDirectory().getPath()+ "/Music/jaihind.mp3"));
if(mp.isPlaying()) {
    mp.pause();
} else {
    mp.start();
}

注意：

mp = MediaPlayer.create(...);

已经准备好返回的MediaPlayer,因此您无法再次调用prepare(或其变体)(并且也不需要onPreparedListener).
