android - No permission to access this object error -

-

i trying upload files using firebase. code works fine on devices internal storage while trying on devices external storage(sd card) shows user not have permission access object. code: -13021 httpresult: 403 error.

my manifest file contains following permissions

<uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.access_wifi_state" /> <uses-permission android:name="android.permission.write_external_storage" /> <uses-permission android:name="android.permission.read_external_storage" />

the default security rules storage buckets require sign in firebase authentication. can use authentication method. @ minimum, must anonymous signin by:

you can set rules allow access -- including have not yet authenticated. but not recommended data not secure.

you need use request.auth in rules instead of auth.

see storageexception: storageexception has occurred. user not have permission access object.

also secure user data more idea.

i hope helps you.
