“重新启动接收器"无法在android系统上运行[Xamarin.Android] [英] “Rebooting receiver” not working android [Xamarin.Android]

问题描述

我正在尝试使用以下代码实现广播接收器，该广播接收器在设备重新启动后会广播，但无法正常工作(设备重新启动后应该向我敬酒)

I am trying to implement a broadcast receiver that gets the broadcast when the device has been rebooted, but is not working (it is supposed to send me a toast when the device has rebooted) with the following code:

广播接收器:

    [BroadcastReceiver]
    public class RebootReceiver : BroadcastReceiver
    {
        public override void OnReceive(Context context, Intent intent)
        {
            if (Intent.ActionBootCompleted.Equals(intent.Action))
            {
                Toast.MakeText(
                    context,
                    "Your app has been rebooted!",
                    ToastLength.Long).Show();
            }
        }
    }

Manifest.xml

Manifest.xml

<receiver android:name=".RebootReceiver">
        <intent-filter>
          <action android:name="android.intent.action.BOOT_COMPLETED"></action>
        </intent-filter>
      </receiver>

清单中的权限

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>

希望有帮助，谢谢

我已经解决了这个问题，@FreakyAli的答案实际上也有助于获得解决方案

I have solved the problem, the answer of @FreakyAli has also helped in fact of getting the solution

创建服务:

[Service(Name = "com.companyname.app.RebootService")]
    public class RebootService : Service
    {
        public override void OnCreate()
        {
            base.OnCreate();
        }

        public override IBinder OnBind(Intent intent)
        {
            return null;
        }
        public override StartCommandResult OnStartCommand(Intent intent, StartCommandFlags flags, int startId)
        {
            Toast.MakeText(this, "Service STARTED!", ToastLength.Long).Show();
            return StartCommandResult.Sticky;
        }

        public override void OnDestroy()
        {
            base.OnDestroy();

            Toast.MakeText(this, "Service STOPED", ToastLength.Long).Show();
        }
    }
}

创建BroadcastReciver:

Create BroadcastReciver:

 [BroadcastReceiver(Enabled =true, Name ="com.companyname.Sortex.RebootReceiver")]
        [IntentFilter(new[] { Intent.ActionBootCompleted })]
        public class RebootReceiver : BroadcastReceiver
        {
            public override void OnReceive(Context context, Intent intent)
            {
            }
        }

在AndroidManifest.xml中注册服务和BroadcastReceiver

register Service and BroadcastReceiver on AndroidManifest.xml

<service android:name="com.companyname.app.RebootService"/>
<receiver android:name="com.companyname.app.RebootReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
    </intent-filter>
</receiver>

在广播接收器的OnReceive方法上调用服务:

Call the service on the OnReceive method of the Broadcast receiver:

Intent serviceIntent = new Intent(context, typeof(RebootService));
context.StartService(serviceIntent);
