IOS Clone to Android App

I have developed an iOS App and would need this app cloned as an Android Version. I have the full iOS source code and also the base Android source code which the app is based upon. All the app needs to do is prompt a login screen which passes the user login credentials into a WebView and saves the credentials so that the app auto logs the user in each time they open the app in future.

I need this completed quickly. I can provide the source codes upon request

Thanks
Nathan
