    <!-- Allows access to the list of accounts in the Accounts Service.

    <p class="note"><strong>Note:</strong> Beginning with Android 6.0 (API level

    23), if an app shares the signature of the authenticator that manages an

    account, it does not need <code>"GET_ACCOUNTS"</code> permission to read

    information about that account. On Android 5.1 and lower, all apps need

    <code>"GET_ACCOUNTS"</code> permission to read information about any

    account.</p>
