Cannot create AWS-SNS GCM account, showing invalid credentials message

Question

I have looked for resources on this particular problem with little luck so far so I thought I would try here.

I am attempting to create an Amazon Web Service Simple Notification Service app in the AWS-SNS console using GCM. I have created the APNS app for the iOS version with no troubles, however, when attempting to create the GCM version I receive the error: "The credentials you entered are invalid. Please enter valid credentials and try again."

In the Google APIs - API Access dashboard I have created both a key for server app and a key for android app. Below are a few screenshots to illustrate the problem.

Any suggestions as to what the problem may be or any instructional documentation recommendations would be tremendously appreciated.

Answer 1

Amazon documentation is very old and not accurate anymore.

When you created your Application and the Credentials on Google Developers Console, from the left menu on Google developer console select:

APIs & auth -> APIs -> Google Cloud Messaging for Android -> Enable API

Answer 2

More on what Rohan has said, it would be on Google's end rather than Amazon's.

Delete the Server API Key in the Google API Console, and create a new one, allowing all IP addresses. Add the new key in AWS SNS, and you should be good to go!
