java为什么应用程序中停止播放音频？

Question

我有一个程序，每次用户做动作时都会播放声音。但是过了一段时间，所有的音频都不起作用了

示例代码：

public void bPressed(View view) {
    MediaPlayer mp = MediaPlayer.create(activity.this, R.raw.audio);
    mp.start();
}

Answer 1

使用MediaPlayer后，需要使用mp.release();：

As an example, consider the problems that could happen if you forgot to release the MediaPlayer when your activity is stopped, but create a new one when the activity starts again. As you may know, when the user changes the screen orientation (or changes the device configuration in another way), the system handles that by restarting the activity (by default), so you might quickly consume all of the system resources as the user rotates the device back and forth between portrait and landscape, because at each orientation change, you create a new MediaPlayer that you never release. (For more information about runtime restarts, see Handling Runtime Changes.)

添加mp.release();例如在onStop()
