为什么我的警报没有响？ （机器人）

Question

我的闹钟在特定时间或根本没有响应（我已尝试将其设置为当前时间的一分钟）。我确保setAlarm()因为日志Log.d("asas", "adasd");关闭而关闭。我不知道有什么问题，如果你知道我怎么解决这个问题，请告诉我。感谢

public void setAlarm(){
    AlarmManager alarmMgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(this, DrawOverAppsService.class);
    PendingIntent alarmIntent = PendingIntent.getActivity(MainActivity.this, 123, intent, 0);
    if(sp.getBoolean("startChecked",false) == true) {
        Log.d("asas", "adasd");
        java.util.Calendar calendar = java.util.Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.set(java.util.Calendar.HOUR_OF_DAY, 19);
        alarmMgr.setRepeating(AlarmManager.RTC,
                calendar.getTimeInMillis(),
                AlarmManager.INTERVAL_DAY, alarmIntent);
    }
    if(sp.getBoolean("startChecked",false) == false) {
        Log.d("asdasd","asdasdasd");
        alarmMgr.cancel(alarmIntent);
    }
}

将PendingIntent alarmIntent = PendingIntent.getActivity(MainActivity.this, 0, intent, 0);更改为PendingIntent alarmIntent = PendingIntent.getService(MainActivity.this, 0, intent, 0);
