Unity调用安卓重启应用

AndroidStudio里

    public void doRestart(int Ntime)
    {
         Log.d("Unity", "========restart "+Ntime);

        Intent restartIntent = getPackageManager()
                .getLaunchIntentForPackage(getPackageName() );
        PendingIntent intent = PendingIntent.getActivity(this, 0,restartIntent,0);
        AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        manager.set(AlarmManager.RTC, System.currentTimeMillis()+Ntime, intent);
        finish();
        android.os.Process.killProcess(android.os.Process.myPid());
    }

unity中的调用

  public static void Restart(int delay)
  {
    AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    AndroidJavaObject mainActivity = jc.GetStatic("currentActivity");
    mainActivity.Call("doRestart", delay);
    jc.Dispose();
    mainActivity.Dispose();
  }
