Question

我在我的Android应用程序中使用SoundPool。在SoundPool中传递以下参数。

spool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);

有时它会在调整音量时在android Rooted设备中发出此异常。

这是我用来播放声音的课程。我在初始化Music_Manager类时调用getInstance()方法＆＃39;实例并在该类中使用该实例中的方法。

public class Music_Manager {

    private SoundPool spool;
    Context mcontext;
    int s1, s2, s3;

    static Music_Manager instance;

    public static Music_Manager getInstance() {
        if (instance == null) {
            instance = new Music_Manager();
        }
        return instance;
    }

    Music_Manager() {
        try {


            spool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);

            s1 = spool.load(mcontext, R.raw.s1, 1);
            s2 = spool.load(mcontext, R.raw.s2, 1);
            s3 = spool.load(mcontext, R.raw.s3, 1);
        }catch (UnsatisfiedLinkError e) {
            // TODO: handle exception
        } 
        catch (Exception e) {
            // TODO: handle exception
        }
    }


    public void playS1() {
        try {
            spool.play(s1, 100, 100, 1, 0, 1);
        } catch (Exception e) {
            // TODO: handle exception
        }
    }

    public void playS2() {
        try {
            spool.play(s2, 100, 100, 1, 0, 1);
        } catch (Exception e) {
            // TODO: handle exception
        }
    }

    public void playS3() {
        try {
            spool.play(s3, 100, 100, 1, 0, 1);
        } catch (Exception e) {
            // TODO: handle exception
        }
    }


    public void release() {

        try
        {
            if (spool != null)
                spool.release();
            }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }

}
