Xamarin.android 推送通知未到达

我正在使用Xamarin开发一个android应用程序，对于推送通知，我正在使用PushSharp。 我在应用程序未运行时（例如，重新启动后）接收推送通知时遇到一些问题。以下是服务代码：

[BroadcastReceiver(Permission=GCMConstants.PERMISSION_GCM_INTENTS)]
    [IntentFilter(new string[] { GCMConstants.INTENT_FROM_GCM_MESSAGE }, Categories = new string[] { "com.xxx" })]
    [IntentFilter(new string[] { GCMConstants.INTENT_FROM_GCM_REGISTRATION_CALLBACK }, Categories = new string[] { "com.xxx" })]
    [IntentFilter(new string[] { GCMConstants.INTENT_FROM_GCM_LIBRARY_RETRY }, Categories = new string[] { "com.xxx" })]
    [IntentFilter(new[] { Android.Content.Intent.ActionBootCompleted })]
    public class PushHandlerBroadcastReceiver : PushHandlerBroadcastReceiverBase<PushHandlerService>
    {
        //IMPORTANT: Change this to your own Sender ID!
        //The SENDER_ID is your Google API Console App Project ID.
        //  Be sure to get the right Project ID from your Google APIs Console.  It's not the named project ID that appears in the Overview,
        //  but instead the numeric project id in the url: eg: https://code.google.com/apis/console/?pli=1#project:785671162406:overview
        //  where 785671162406 is the project id, which is the SENDER_ID to use!
        public static string[] SENDER_IDS = new string[] {"1234"};

        public const string TAG = "PushSharp-GCM";
    }

我错过什么了吗？手机重新启动后，为什么服务没有启动。我应该在广播接收器里做些什么吗？我是否应该注册到服务构造函数中的推送通知（以处理应用程序尚未启动的情况）？

如果您的服务在重新启动时未启动，则可以向启动它的项目添加一个

广播接收器

：

[BroadcastReceiver]
[IntentFilter(new[] { Intent.ActionBootCompleted })]
public class MyBootReceiver : BroadcastReceiver
{
    public override void OnReceive(Context context, Intent intent)
    {
        MyNotificationService.RunIntentInService(context, intent);
        SetResult(Result.Ok, null, null);
    }
}

如果您使用的是

PushSharp

，您可能不需要将该过滤器添加到

PushHandlerBroadcastReceiverBase

实现中。

我尝试过，但它似乎忽略了这种类型的广播接收器。。。我正在努力找出原因…我昨天一整天都在处理通知，我尝试重新启动设备，但在使用intent筛选器时无法重现此问题。所以你一定是做错了什么，或者你让一个任务经理在杀东西。我会再给它一次机会，看看会发生什么。我试过了，但它不起作用：（我很沮丧。我只是没有得到完整的引导。）。

[Service] //Must use the service tag
    public class PushHandlerService : PushHandlerServiceBase
    {
        public PushHandlerService () : base (PushHandlerBroadcastReceiver.SENDER_IDS)
        {
        }

        protected override void OnRegistered (Context context, string registrationId)
        {
            ...
        }

        protected override void OnUnRegistered (Context context, string registrationId)
        {
            ...

        }

        protected override void OnMessage (Context context, Intent intent)
        {
            ...
        }

        protected override bool OnRecoverableError (Context context, string errorId)
        {
            ...
        }

        protected override void OnError (Context context, string errorId)
        {
            ...
        }

        void createNotification (string title, string desc, Intent intent)
        {
            ...
        }
    }

[BroadcastReceiver]
[IntentFilter(new[] { Intent.ActionBootCompleted })]
public class MyBootReceiver : BroadcastReceiver
{
    public override void OnReceive(Context context, Intent intent)
    {
        MyNotificationService.RunIntentInService(context, intent);
        SetResult(Result.Ok, null, null);
    }
}
