    Intent openMainActivity=new Intent("com.example.darshanms.MAINACTIVITY");

                    startActivity(openMainActivity);

                }

            }

        };

        timer.start();


    }

    @Override

    protected void onPause() {

        super.onPause();

        mp.release();

        finish();

    }

}

我试着在小应用程序中播放音乐。我的Android设备可以产生输出，但不能播放音乐。

尝试切换这一行：

mp=MediaPlayer.create(splash.this, R.raw.splashsound);

mp.reset();

mp.start();

使用：

mp=MediaPlayer.create(this, R.raw.splashsound);
mp.prepare();
mp.start();
