Question

我已经尝试过第一次Azure推送通知，现在实施后，我会被onMessage接收。 OnMessage收到没有被击中。应用程序成功注册。我没有在AndroidManifest文件中做任何更改，我正在上传代码。下面几个设置： - 套餐名称： - pACKAGE_NAME

 [assembly: Permission(Name = "pACKAGE_NAME.permission.C2D_MESSAGE")] [assembly: UsesPermission(Name = "pACKAGE_NAME.permission.C2D_MESSAGE")] [assembly: UsesPermission(Name = "com.google.android.c2dm.permission.RECEIVE")] [assembly: UsesPermission(Name = "android.permission.GET_ACCOUNTS")] [assembly: UsesPermission(Name = "android.permission.INTERNET")] [assembly: UsesPermission(Name = "android.permission.WAKE_LOCK")]

我已经准备了一个带有通知中心的XAMARIN论坛示例APP。这是链接：https://1drv.ms/u/s!AuKd5Hvq8SOlo8Fukh4KcX6GtIoPmQ。

与您的代码比较，看看您是否遗漏了任何内容。此应用程序使用Xamarin.GooglePlayServices.Gcm软件包版本25.0.0（而不是最新版本：29.0.0.2）。

谢谢，
