从 raw 播放音频时 avd 崩溃

Question

我最近一直在开发二十一点游戏，我一直让程序运行顺利，直到我开始将原始文件夹中的音频集成到我的项目中。现在，每次我运行应用程序时它都会崩溃。我一直在尝试解决这个问题大约一个星期，但没有成功。也许有人可以解决这个难题。这是我正在努力解决的代码块：

final Button redeal = (Button) findViewById(R.id.redeal);
redeal.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        MediaPlayer m = new MediaPlayer();
        m = MediaPlayer.create(getBaseContext(), R.raw.shuffle);
        String path = "android.resource://" + "/" + R.raw.shuffle;
        try {
             //m.setDataSource(context, Uri.parse(path));
            m.prepare();
            m.start();
            redeal.playSoundEffect(R.raw.shuffle);
            reDeal();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
});

这是我的日志：

关于如何让它发挥作用的任何想法？

Answer 1

在你的 onClick() 函数中试试这个代码：

MediaPlayer mp =MediaPlayer.create(YOUR_CLASS_NAME.this, R.raw.shuffle);
mp.start();
