Notification is received but not displayed using Parse Unity SDK + Android

I’m using Parse Unity SDK for Android.

I’ve managed to register the device successfully.

 void Start() {
    	//Parse Installation
    	if (ParseInstallation.CurrentInstallation != null && !string.IsNullOrEmpty(ParseInstallation.CurrentInstallation.DeviceToken))
    	{
    		Debug.Log("Device Token : " + ParseInstallation.CurrentInstallation.DeviceToken);
    	}
    	else
    	{
    		ParseInstallation installation = ParseInstallation.CurrentInstallation;
    		installation.Channels = new List<string> { Config.Instance.GetUserInfo().GetEmail() };
    		installation.SaveAsync().ContinueWith(t => {
    			if (t.IsFaulted || t.IsCanceled)
    			{
    				Debug.Log("Push subscription failed.");
    			}
    			else
    			{
    				Debug.Log("Push subscription success.");
    			}
    		});
    		
    		
    		//installation.
    	}
    }

Only to discover that the notification is “received” but not being displayed neither in the app nor in the notifications bar.

    I/GCM     ( 1285): GCM message com.ahmed.app 0:1433935471473270%3f8fc5dbf9fd7ecd
    I/ParsePushService( 7057): Push notification received. Payload: {"alert":"test","push_hash":"098f6bcd4621d373cade4e832627b4f6"}
    I/ParsePushService( 7057): Push notification is handled while the app is foregrounded.
    W/GCM-DMM ( 1285): broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE pkg=com.ahmed.app (has extras) }

Also, Unity does not receive the notification (see code)

   void Awake() {
    		ParsePush.ParsePushNotificationReceived += (sender, args) => {
    			#if UNITY_ANDROID
    			AndroidJavaClass parseUnityHelper = new AndroidJavaClass("com.parse.ParseUnityHelper");
    			AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    			AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
    
    			//Debugging the payload
    			Debug.Log("Calling Parse from Unity and Payload is : " + args.StringPayload);
    			
    			// Call default behavior.
    			parseUnityHelper.CallStatic("handleParsePushNotificationReceived", currentActivity, args.StringPayload);
    
    
    			#endif
    		};
    	}

This event doesn’t get triggered.

Here’s my AndroidManifest.xml

      </application>
   </manifest>

Any idea what’s the problem?

Rather than downloading the SDK manually, I’ve downloaded the Parse Push sample project and copied the files to my project.
Using the SDK 1.5.2 sample project, it works now.
