在我的应用程序中有几个短(不到1秒(的声音。因此MediaPlayer根据图表(https://developer.android.com/images/mediaplayer_state_diagram.gif(。
我想再播放一遍。它工作得很好，直到几次最小化和恢复应用程序-然后没有声音，在logCat中，我可以看到错误：
start called in state 0, mPlayer(0x90279300)
E/MediaPlayer: error (-38, 0)
E/MediaPlayer: Error (-38,0)
在活动类的顶部是媒体播放器定义的(所有声音(，如下所示：
private MediaPlayer mpStart;
以及在onCreate:中
mpStart = MediaPlayer.create(this, R.raw.gong);
播放声音时使用：
mpStart.start();
在其他一些功能中。。。
由于在最小化应用程序过程中出现问题，我再次尝试在onResume 中添加
mpStart = MediaPlayer.create(this, R.raw.gong);
但这于事无补。
开始前我已测试添加mpStart.pause((或stop((和prepare((，但问题仍然存在。
我正在使用API 23
事实是，您在任何时候都不会停止媒体播放器。
在你的点击监听器结构中，你的代码是
1.停止播放((；2.mpStart=MediaPlayer.create(PlayaudioActivity.this，(此处为您的音频原始文件(；3.mpStart.start((；
下面是stopPlaying((函数。
private void stopPlaying() {
if (mpStart!= null) {
mpStart.stop();
mpStart.release();
mpStart= null;
}
}
所以我把每个start((都改为：
if (mpStop != null) {
mpStop.stop();
mpStop.release();
mpStop = null;
}
mpStop = MediaPlayer.create(kontext, R.raw.zvukovy_signal_konec);
mpStop.start();
我已经对这个应用程序进行了大量的最小化和阿根宁恢复测试，不幸的是，一段时间后它再次停止播放声音。
这里有一个更长的日志，有几次播放声音的尝试：
