Account access permissions

Hello.
I am developing NextcloudServices app. Recently one of users have experinced issue with logging-in via SingleSignOn(issue #22) on older Android version. So I have added permissions connected with accounts:

    <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.READ_SYNC_SETTINGS" />
    <uses-permission android:name="android.permission.WRITE_SYNC_SETTINGS" />
    <uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />
    <uses-permission android:name="android.permission.USE_CREDENTIALS" />

But still in the emulator(AOSP 7.1.1) app shows the error about permissions. In the log following error is displayed whenever authentication is attempted:

2021-10-05 14:34:41.220 2512-2512/com.polar.nextcloudservices E/com.nextcloud.android.sso.AccountImporter: Permission not granted yet!

Reproduce the authentication attempt on the AOSP 7.1.1 emulator and start from the AccountImporter log message, checking how the listed account permissions are evaluated. Done means the permission error no longer appears and SingleSignOn authentication succeeds on the affected Android version.
