In order to integrate XenMobile with the Google Play Store, a Public App Store you will need to configure your Google Play Credentials. Beside the user name and password, you will also need to enter the Device ID (Configure > Settings > More > Server > Google Play Credentials)
I went ahead entering the account credentials and Device ID supplied by the customer. While trying to save the Google Play configuration an error message appears “The Google logon request used a user name or password that is not recognized”.
