Allows access to the list of accounts in the Accounts Service. Note: 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 'GET_ACCOUNTS' permission to read information about that account. On Android 5.1 and lower, all apps need 'GET_ACCOUNTS' permission to read information about any account.
Allows an app to create windows using the type TYPE_APPLICATION_OVERLAY, shown on top of all other apps. Very few apps should use this permission; these windows are intended for system-level interaction with the user. Note: If the app targets API level 23 or higher, the app user must explicitly grant this permission to the app through a permission management screen. The app requests the user's approval by sending an intent with action ACTION_MANAGE_OVERLAY_PERMISSION. The app can check whether it has this authorization by calling android.provider.Settings#canDrawOverlays Settings.canDrawOverlays()
