BUG: Connect IQ Oauth2 Authorisation malforming URLs in Android Connect IQ store app

When making a call via the connect IQ API (Authentication.makeOAuthRequest)

The Android Connect IQ store app is malforming the request

It should be sending a request to the default browser as

https://requesturl?parameter1=xxx&parameter2=yyy

 . but instead it is sending the request as 

https://requesturl&parameter1=xxx&parameter2=yyy 

In other words it is not forming the query string properly from the parameters passed to the Connect IQ API

The iOS Android Connect IQ Store app handles it correctly
