MediaPlayer出错: E/MediaPlayer: Error (1，-19) - Android

Question

我知道有一些类似的问题，但没有一个回答我的问题。当我单击一个按钮时，会调用媒体播放器，这会出现在日志中。

06-02 00:20:38.980 26035-26035/myapp.com.facadezpontos E/MediaPlayer-JNI: QCMediaPlayer mediaplayer NOT present
06-02 00:20:39.019 26035-26035/myapp.com.facadezpontos E/MediaPlayer: Should have subtitle controller already set
06-02 00:20:39.026 26035-26035/myapp.com.facadezpontos E/MediaPlayer: Should have subtitle controller already set

过了一段时间后，上面的消息被替换为波纹，媒体播放器提供的声音不再播放。

06-02 00:23:21.396 28749-28749/myapp.com.facadezpontos E/MediaPlayer: Error (1,-19)

这是MediaPlayer的代码

public void buttonClick(Context context, MediaPlayer mp){
        mp = MediaPlayer.create(context, R.raw.bubble_nice);
        mp.start();
    }
