Google Account Sign in problem

Nobody has claimed this yet.

First of all thanks for your effort. I am using this source to create a browser app for my personal use.

When i compiled this source code and run it on my device, it prompts me to add a google account, when i tap on "Add an Account" it checks for account information but doesn't find my already attached google account, if i try to add the same account that i have already attached with the device, it gives error saying that this account already exists.

if i remove the attached gmail account from settings first, or If i add a different account, then the account is successfully added but this browser app still didn't get the account credentials and brought me back to same screen to add the account. Although account was added to device, visible in the settings screen and all other google apps were able to use added account.

Ideally like all other Google apps or any app with google signup enabled, this app should be able to fetch the attached gmail account and use it instead of asking user to add an account.

Any idea how can i fix this?

Start by reproducing the sign-in flow on an Android device with an existing Google account, then trace the account-addition and credential retrieval entry points. Done means the app recognizes an attached account, avoids treating it as a duplicate, and proceeds with that account's credentials.
