我正在使用以下代码在特定日期设置警报。

我应该在 android 清单中添加什么以保持警报功能，即使在关闭电源和关闭再打开之后也是如此？

    Calendar cal = Calendar.getInstance(TimeZone.getDefault(), Locale.getDefault());
   //cal.add(Calendar.SECOND, 10);

      cal.set(Calendar.DATE,19);  //1-31
    cal.set(Calendar.MONTH,Calendar.DECEMBER);  //first month is 0!!! January is zero!!!
   cal.set(Calendar.YEAR,2012);//year...

    cal.set(Calendar.HOUR_OF_DAY, 16);  //HOUR
    cal.set(Calendar.MINUTE, 39);       //MIN
     cal.set(Calendar.SECOND, 10);       //SEC


       // Create a new PendingIntent and add it to the AlarmManager
    Intent intent = new Intent(MainActivity.this, alarmAct.class);
     PendingIntent pendingIntent = PendingIntent.getService(MainActivity.this, 0,intent, 0);

     //or if you start an Activity
      //PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0,intent, 0);

         AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
      am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

我已将此添加到清单中：

          <service android:name=".MyAlarmService" />

有人知道怎么用RTC_WAKEUP吗？

您需要做的是注册一个BroadcastReceiver使用该操作的

<action android:name="android.intent.action.BOOT_COMPLETED" />

在那个接收器中，您开始备份警报和您需要的任何服务
