我需要AlarmReceiver在10秒后启动活动(例如).我需要在不运行应用程序的情况下激活它.但无论应用程序是否运行,AlarmReceiver都不会被调用.有什么建议？

Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 111, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

//alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() 
                                          //+ (10 * 1000), pendingIntent);
Toast.makeText(this, "Alarm set", Toast.LENGTH_LONG).show();
