Question

我正在使用AlarmManager的服务，每30分钟触发一次我的服务接收器＆＃34;用于调度通知。为了测试的目的，我已经降低了这个间隔。我的应用程序和它的服务运行完全正常并且能够提供Notifications.However在重新启动后我的服务突然停止并且消息被传递说＆＃34; App停止工作＆＃34;。

我写过这段代码的灵感源自here，here以及其他许多SO问题，过去12小时内一直试图解决这个问题。我怀疑问题出现在RebootReceiver或我的清单中。但是代码很简单，适用于其他人。

我的App Manifest：

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="Namaz_Pro.Namaz_Pro" android:versionCode="1" android:versionName="1.0" android:installLocation="preferExternal">
    <uses-sdk android:minSdkVersion="17" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <application android:label="Namaz Pro">

        <receiver android:name=".ServiceReceiver" />
        <receiver android:name=".NotificationPublisher" />
    <receiver android:name=".RebootReceiver"
              android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
      <intent-filter>
        <category android:name="android.intent.category.DEFAULT" />
       <action android:name="android.intent.action.BOOT_COMPLETED" />
      <action android:name="android.intent.action.QUICKBOOT_POWERON"/>
      </intent-filter>
    </receiver>
    <service android:name=".NotificationService"/>
    </application>
</manifest>

我的RebootReceiver：

[BroadcastReceiver]
    class RebootReceiver : BroadcastReceiver
    {
        public override void OnReceive(Context context, Intent intent)
        {
            if ("android.intent.action.BOOT_COMPLETED".Equals(intent.Action))
            {

                Intent startServiceIntent = new Intent(context, typeof(NotificationService));
                context.StartService(startServiceIntent);
            }

        }
    }

我的服务：

[Service]
    class NotificationService : Android.App.Service
    {



        public override StartCommandResult OnStartCommand(Intent intent, [GeneratedEnum] StartCommandFlags flags, int startId)
        {



            var alarmIntent = new Intent(this, typeof(ServiceReceiver));
            var pending = PendingIntent.GetBroadcast(this, 1234567, alarmIntent, PendingIntentFlags.UpdateCurrent);

            var alarmManager = GetSystemService(AlarmService) as AlarmManager;
            alarmManager.SetRepeating(AlarmType.RtcWakeup, App_Code.helperMethods.CurrentTimeMillis() + 10000, 60000 , pending);


            return StartCommandResult.NotSticky;
        }
        public override void OnDestroy()
        {
            base.OnDestroy();

            //Log.Debug(TAG, "Simple Service Destroyed at {0}.", DateTime.UtcNow);
        }



        public override IBinder OnBind(Intent intent)
        {

            return null;
        }
    }

我的服务接收者：

[BroadcastReceiver]
public class ServiceReceiver : BroadcastReceiver
{
        notificationHelper.setUpNotifications(Android.App.Application.Context);

    }
}

Xamarin.Android服务在重启时没有重启＆＃34; App Stopped＆＃34;信息
