拥有共享元素动画以及自定义输入动画会导致活动泄漏.

知道可能是什么原因？

我为我的应用程序发出了一声简单的警报声.但问题是声音是在某些设备上播放的,而在其他设备上则没有.

示例代码如下:

public void audioPlayer() { // leshon tingull kur ka kolision //Armando 8/7/2013
        MediaPlayer beep_alert = MediaPlayer.create(Maps.this,R.raw.double_beep);
        try {
            beep_alert.start();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

没有显示错误,它只是不玩,例如nexus 4,但它可以播放nexus 7.

出了什么问题？

double_beep是一个mp3文件.
