Unable to create a folder in android 11. Tried using DocumentDir & SDCardApplicationDir in place of MainBundleDir as well but of no use. It is important to create a folder as we are storing a list of messages which are being sent by the admin so that the app remains accessible even if the mobile data is switched off.

Answer 1

Android 11+ needs the permission MANAGE_EXTERNAL_STORAGE alongside with WRITE_EXTERNAL_STORAGE for any file management to work as itended.

Don't forget to add <uses-permission android:name="android.permission.ACCESS_MEDIA_LOCATION" /> and android:requestLegacyExternalStorage="true" on your manifest.xml file
