Parse Push Notfications in MonoDroid

问题

So I'm using the Parse component from the Xamarin store in my MonoDroid app. So I was able to use the following code to store an object

ParseClient.Initialize ("appid", "windowskey");

var obj = new ParseObject("Note");
obj ["text"] = "Hello, world!  This is a Xamarin app using Parse!";
obj ["tags"] = new List<string> {"welcome", "xamarin", "parse"};
obj.SaveAsync ();

My real goal is to be able to do push notifications. Even though the above object stored, Parse did not register the device in the installations to be able to send push notifications. What else am I missing. Note: I'm doing this in the emulator but if i'm not mistaken it still should work.

@basit-zia, yes I did! I had to create a binding for the push library from the Java Parse SDK. I believe I was able to strip away all the libraries except for the necessary elements. I can't remember exactly what I did though.

Then in the Main Activity class, I put the following into the OnStart() method:

            // check for a notification
            if (Intent != null)
                try {
                string jsonString = Intent.Extras.GetString("com.parse.Data");
                PushObject jsonObj = JsonConvert.DeserializeObject<PushObject>(jsonString);

                if (jsonObj.alert != null) {
                    Toast.MakeText (BaseContext, jsonObj.alert, ToastLength.Long).Show ();
                }

                } catch (Exception e) {
                    Console.WriteLine ("JSONException: " + e.Message);
                }

And put the following into the OnCreate() method:

            Com.Parse.Parse.Initialize(this, "app id here"}, "client key here");
            PushService.SetDefaultPushCallback (this, this.Class);
            PushService.StartServiceIfRequired (this);
            ParseInstallation.CurrentInstallation.SaveInBackground ();
