I think what you want is to use AccountManager

To find out what type the google account is, use something like:

AuthenticatorDescription[] types = mAccountManager.getAuthenticatorTypes(); //
for (AuthenticatorDescription type : types) {
  Log.d("account types", type.type);
}

Then do something like

AccountManager mAccountManager = AccountManager.get(context);
Account[] mAccounts = AccountManager.get(context).getAccountsByType("com.google");
// Choose which account to use if there are multiple google accounts registered, save to Account mAccount
AccountManagerFuture response = mAccountManager.getAuthToken(mAccount, type, options, activity, mCallback, mHandler); // define callback and handler yourself for where to return

When the user reaches mCallback in your mHandler, the login process is done. The usual google login dialogue will be used if the user is not already logged in to his/her Google account.

Try it out for yourself and let me know if it helped you!
