添加警报管理器时遇到问题。
基本上，我正在尝试在特定时间添加警报，无论应用是在后台还是在前台，它都可以正常工作。但是问题是，当应用程序从后台删除或应用程序被杀死时，它不会触发。
我想触发警报，无论应用程序是否正在运行（关闭应用程序时都会出现。）>
我有点绝望。
这是我的代码：
public class AlarmReciver extends BroadcastReceiver { public AlarmReciver(){ super(); } @Override public void onReceive(Context context, Intent intent) { Log.d("called","called"); Toast.makeText(context, "Alarm received!", Toast.LENGTH_LONG).show(); //This will send a notification message and show notification in notification tray /* ComponentName comp = new ComponentName(context.getPackageName(), AlarmNotificationService.class.getName()); startWakefulService(context, (intent.setComponent(comp)));*/ try { ManageDatabase manageDatabase = new ManageDatabase(); // manageDatabase.setupdatabase(context); // For our recurring task, we'll just display a message // Toast.makeText(context, "Alarm received!", Toast.LENGTH_LONG).show(); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); String today_date=String.valueOf(calendar.get(Calendar.DAY_OF_MONTH))+"/"+String.valueOf((calendar.get(Calendar.MONTH)+1))+"/"+String.valueOf(calendar.get(Calendar.YEAR)); today_date= datetimeformat.getdate(today_date); String id = intent.getStringExtra("id").toString(); String pid = intent.getStringExtra("pid").toString(); manageDatabase.cancelallreminders_without_update(context); manageDatabase.setallactivatedalarm(context); manageDatabase.addtodaysidlist(id,today_date,context); // Enable a receiver /* ComponentName receiver = new ComponentName(context, AlarmReciver.class); PackageManager pm = context.getPackageManager(); pm.setComponentEnabledSetting(receiver, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);*/ Intent service1 = new Intent(context, Show_Reminder.class); service1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); service1.putExtra("id", id); service1.putExtra("pid", pid); context.startActivity(service1); Toast.makeText(context,"alarm is triggered...", Toast.LENGTH_LONG).show(); Log.d("alarm is","triggered"); }catch (Exception e) { Log.e("error",e.toString()); e.printStackTrace(); } } }清单文件：

关闭应用程序也会关闭所有警报。相反，您需要的是从后台服务设置警报。
