Android: Can I use google ClientLogin for user registration?

Question

We are developing an app that has the option of user registration. Now we want to make this process as easy as possible for the user (to encourage registration), so we basically want the user to login with his google account and our server will simply store his google username (not his password). We are not accessing any google services with the app, but simply want to give an easy option to register and login. Is this something that other apps are doing? Does Google have a problem with that?

Answer 1

I really recommend you to use the AccountManager from Android you don't have any problems with storing the password on your severs if you use the Auth Token. And the biggest benefit is, that the user don't have to enter his email or password http://developer.android.com/reference/android/accounts/AccountManager.html

Look at the steps in the documentation

• Get all available accounts
• View them in a List
• Request a Auth Token
