How to find Gmail account associated with Android Market?

Question

I know how to find accounts (which will include gmail email ids of user) and how to filter gmail account.

AccountManager am = AccountManager.get(context);
        Account[] accounts = am.getAccounts();
        ArrayList<String> googleAccounts = new ArrayList<String>();
        for (Account ac : accounts) {
            String acname = ac.name;
            String actype = ac.type;
            //add only google accounts
            if(ac.type.equals("com.google")) {
                googleAccounts.add(ac.name);
            }
            Log.d(TAG, "accountInfo: " + acname + ":" + actype);
        }
        return googleAccounts;

What I wish to know is how to find the gmail account associated with Android Market? If you will try to delete a gmail account from Android phone you will get this message

but if you try to delete a gmail account associated with Android Market you will get the following message (if you press remove account in the earlier message).

Thanks for the help.

Solution 1

The dialog

is caused by the implementation of AbstractAccountAuthenticator#getAccountRemovalAllowed in the Google account authenticator.

Since calling implementations of AbstractAccountAuthenticator directly is prevented by the system-only permission android.permission.ACCOUNT_MANAGER you're going to have a hard time finding this out on your own.

Solution 2

From what I have found, the first google account added in the device is the primary google address which is associated with android market. Also, we get google accounts in the order it was added in the device. So, accounts[0] will be the first email-Id added.

String marketAssociatedEmailId = "";
Account[] accounts = AccountManager.get(context).getAccountsByType("com.google");
if(accounts.length > 0) {
  marketAssociatedEmailId = accounts[0].name;
}

Again, I am not sure about this. You have to test it yourself with various scenarios.
