'Cannot read property 'listRegistrationsByTag' of undefined' from Microsoft.WindowsAzure.MobileServices.Push.RegisterAsync

This is a Xamarin.Forms app running on Android, based on the Azure getting started Mobile App example.
I'm trying to register a device's id for notification services. Originally I was getting unauthorized, so I relaxed authorization settings on the backend. Now I am getting this error and cannot find a reason why.
I checked and double checked that notification hub has the correct Firebase details that align with the app and cannot see what the problem is here, any help appreciated.

John,
If you set WEBSITE_PUSH_ENABLED=false in your appsettings, does the problem go away?
Can you check your Mobile App's app settings?
Specifically, I am looking for the existence of the app setting "MS_NotificationHubName". If that app setting doesn't exist, you need to add it, with the name of your notification hub.

There is a bug in the Azure App Service Push blade right now. A fix is being rolled out. In the interim, instead of using RegisterAsync(), use the method described in the book http://aka.ms/zumobook - chapter 5.

How to integrate push services from AWS Mobile Hub sample project in an existing android project?

I have created an android sample project using AWS Mobile Hub with User Sign-In and Push Notifications services.
I've downloaded the project and opened it through Android Studio, in order to take the necessary files for push notifications from the sample project and to integrate it in my existing Android app.
I thought it would be simple, but then I found out this huge files branch:
It is difficult to understand what files I do need and what files I don't need. Could you please help me to figure out what do I need to import into my existing project in order to integrate Push Notifications in my app?

You should copy the contents of MySampleApp/app/src/main/java/com/amazonaws verbatim into your new project and Also parts of AndroidManifest.xml and build.gradle and Application.java.
For a complete instruction, I would recommend that you go through Mobile Hub Console > Project Name > Build > Select Android > On Left side go to develop > Use as an Example.
You will find all the instructions you need for your android project

The "PushListenerService" class is basically a useful example class where the magic happens. So keep every file that support that class. The
private static void generateNotification(Context context, final String message)
is what displays the notification message.
Another important note is how to get the user's device endpoint value. This can be gotten using the "PushManager" class.
String endpoint = pushManager.getEndpointArn();
The endpoint ARN of a device help you send direct notification to that device.
PublishRequest publishRequest = new PublishRequest();
publishRequest.setMessage(message);
publishRequest.setSubject(subject);
publishRequest.withTargetArn(endpoint); //This can also be a "topic" ARN
snsClient.publish(publishRequest);
Pretty nice job done by the guys at AWS. Big thanks to them! :D
There is no easy way out. Just take your time and go through all the code in the classes that relate to the AWS service you want to implement. Good luck!
Btw, make sure your app is not open on the test device when you send a notification to it or else you won't see a notification since your app is already running. I notice this is a default behaviour.

Push notification from Mixpanel dashboard to Android Cordova app

I am successfully sending Push Notifications from the Mixpanel Dashboard to a Cordova app on both iOS and Android devices, using phonegap-plugin-push.
However, the title and body values entered in the default fields only appear on iOS devices.
For the notification to appear on Android devices, I currently need to include a custom payload in Mixpanels "Custom Data":
{
"title":"Title for Android only",
"body":"Content for Android only"
}
This is an error prone step for any non-technical using Mixpanel to send notifications.
Does someone know an easier way to do this?

The short answer here is that Cordova/Phonegap and similar third party frameworks are not 100% optimized for Mixpanel functionality (although they work pretty great), and as such you'll need to generate separate push notifications for both iOS and Android in your Mixpanel project.
Providing context, all iOS pushes regardless of app deliver a JSON payload to APN using the same keys to deliver their messages (alert, badge, sound). However, the keys that Android apps process for incoming GCM pushes are entirely dependent on how the GCM receiver is established, and therein lies the problem here.
Mixpanel's Android SDK initializes pushes and uses a GCM receiver that is specific to Mixpanel messages, and fully expects its custom keys (mp_message, mp_title) in order to render the notification. The webapp reformats the message input to meet these key requirements (http://bit.ly/1OGgU1y)
However, the Phonegap GCM receiver expects different keys as you've noticed. I'd recommend referring to the phonegap github page in order to get more context into the expected push format and behavior (looks like they expect "title" and "message" as the keys): http://bit.ly/1KDScye
Unfortunately, what this means is that the Android app is not optimized to receive the default, web-app generated Mixpanel pushes, although your iOS one is. Mixpanel's SDKs are intended to maximize capabilities for that platform, and it isn't guaranteed that Cordova or similar JS frameworks will translate 100%.
So to conclude - Creating a message in the Mixpanel push editor will send to iOS, but for Android you'll need to use the custom JSON payload in a separate notification, including keys that the phonegap GCM receiver is compatible with.

If its help to anyone this is how I solved the problem
in phonegap-plugin-push
you need to modify two files
GCMIntentService.java
private String normalizeKey(String key) {
if (key.equals(BODY) || key.equals(ALERT) || key.equals(MP_MESSAGE) || key.equals(GCM_NOTIFICATION_BODY)) { // added MP_MESSAGE
PushConstants.java
public static final String MP_MESSAGE = "mp_message";

Rich push in Urbanairship in android

I am implementing Push Notification for Android in my project. I am implementing urbanairship GCM push Notification.While i gone through the urbanairship site, i camr to notice that under the messages tab, there is an option for "TEST RICH PUSH". I have already done tested simple push by sending push messages from "TEST PUSH" under the tab messsages. Now my question is in "TEST RICH PUSH", there are two new fields "USER" and "ALIAS". Is Rich push is used for sending push notification only to a particualar user currently using an App. or it has got any other purpose. Also please let me know how to enable "RICH PUSH" in their new website.(Earlier it is staright forward. Now i looked in their whole website, But i couldn't find a clue). Any help in this is highly appreciated.`
Thanks InAdvance

Rich Push is automatically apart of the Urban Airship library (at least since 3.0.0 version, probably before then as well but I'm not sure which version number). There are just a few things in code you have to do to get it up and started.
In your airshipconfig.properties file add the line "richPushEnabled = true" (without quotes).
In your manifest file add a service with the name "com.urbanairship.richpush.RichPushUpdateService" along with the PushService/PushWorkerService, etc.
And you should be good to go! If not let me know I may have forgotten something.
To send a push you have to use the curl command found here (Under Rich Push -> Rich Push broadcast): https://support.urbanairship.com/customer/portal/articles/1069013-helpful-curl-examples under audience instead of doing "all", spit out this value to the logs somewhere once UA is initialized: RichPushManager.shared().getRichPushUser().getId() (import com.urbanairship.richpush.*;) and make sure the MasterSecret parameter is NOT your api secret but the master secret found in your API keys on your UA developer dashboard.
I wrote everything out because Urban Airship's documentation DNE for android Rich Pushes, it's absolutely horrible. They have a sample project but that's it.

Push Messages for PhoneGap

I created an app for iPhone and Android using Phonegap.
Now I wanted to add push functionality which already works pretty good.
When a push message arrives on my iPhone I get a message on the homescreen. If I swipe it, iOS will open my application. - So far so good.
Now, within my PhoneGap app I need to check what that message actually says in order to open the correct view within my app via JavaScript.
I know there are quite some posts about this but I couldn't find some clear answers to these questions:
Does PhoneGap support push messages?
If yes, where is the documentation for that?
If not, which plugins/frameworks can be recommended? So far I found pushwoosh and Urbanair. Are they any good?
Regarding Pushwoosh, I noticed that I need some kind of pushwoosh ID - Why that?

By Pushwoosh ID you most probably mean Pushwoosh App Id or Application Code. It's an ID of your application in Pushwoosh Control Panel (current format is XXXXX-XXXXX). You will see it as soon as you add a new app in Pushwoosh.
There was quite an extensive blog post made by Holly Schinsky on easy PhoneGap integration with Pushwoosh
http://devgirl.org/2012/12/04/easy-phonegap-push-notifications-with-pushwoosh/
It should be very helpful for all PhoneGap developers aiming to integrate push notifications into their apps.

I found a really easy solution without using a framework.
I simply added the following code to the very end of the method didFinishLaunchingWithOptions (Right before the return statement):
if (launchOptions != nil)
{
NSDictionary* dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (dictionary != nil)
{
NSLog(#"Launched from push notification: %#", dictionary);
[self addMessageFromRemoteNotification:dictionary updateUI:NO];
}
}
Also, I added this new method to my AppDelegate.m which gets the payload from the push message:
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{
NSLog(#"Received notification: %#", userInfo);
[self addMessageFromRemoteNotification:userInfo updateUI:YES];
}
(The NSLog calls above will show you what's inside the push message)
As a last step, I added this listener to do what ever I want with the payload:
- (void)addMessageFromRemoteNotification:(NSDictionary*)userInfo updateUI:(BOOL)updateUI
{
// do what ever you want with userInfo
}
If you want to do an additional JavaScript call with this info, I recommend using:
[self.viewController.webView stringByEvaluatingJavaScriptFromString:#"callSomeJSFunction()"];
Of course you can also pass arguments as strings into that JS function if you want.
