android - Pick an email using AccountPicker.newChooseAccountIntent

Question

I'm trying to let the user pick an Email account using the following code:

Intent intent = AccountPicker.newChooseAccountIntent(null, null, new String[]{"com.google"},
                            false, null, null, null, null);
                    startActivityForResult(intent, 23);

This code works great but if the user doesn't have a Gmail account but Yahoo, Hotmail, etc.. How can I show all Email accounts by changing the third parameter:

new String[]{"com.google"}

Thank you very much

Answer 1

According to the docs, the third parameter is allowableAccountTypes:

allowableAccountTypes

an optional string array of account types. These are used both to filter the shown accounts and to filter the list of account types that are shown when adding an account.

For IMAP accounts in Email app that type is being returned as "com.google.android.legacyimap" (please do not log accounts' details in production):

AccountManager accountManager = AccountManager.get(getApplicationContext());
Account[] accounts = accountManager.getAccountsByType(null);
for (Account account : accounts) {
    Log.d(TAG, "account: " + account.name + " : " + account.type);
}

That's using (add all account types you need to the array)

Intent intent = AccountPicker.newChooseAccountIntent(null, null,
        new String[] {"com.google", "com.google.android.legacyimap"},
        false, null, null, null, null);

is returning following on my device:

Please note that AccountPicker class is part of Google Play Services package, one could use AccountManager.newChooseAccountIntent() (added in API level 14) instead and get the same results.

Hope this helps.
