Android Question targetSdkVersion="33" and permissions

[peacemaker]

Hi, All

I have found that if targetSdkVersion is "33" - no PERMISSION_WRITE_EXTERNAL_STORAGE is shown in the app settings. And no request system dialog and Waiting For permission request is always with False result.
It's in B4xPages structure app, tested under Android 13 device and 2 emulators (Android 10).
B4A v.12.5, rp lib v.1.20.

Just changed into targetSdkVersion="32" - no problem with the dialog and app work.
Is it known ?

The external storage permission cannot be used since at least targetSdkVersion=31.

Other methods are available: https://www.b4x.com/android/forum/t...-folder-list-of-other-related-methods.129897/

I'm making a picture gallery app using SimpleMediaManager and any local available photos. Without this permission no files gotten.

Starting from targetSdkVersion=29 (Android 10) you cannot directly access the external storage. Maybe you previously used requestLegacyExternalStorage which works until targetSdkVersion=30.

requestLegacyExternalStorage

Never used... And how to make "my_own_gallery" to process my tons of pictures from whole the device?

SOLVED:

https://developer.android.com/reference/android/Manifest.permission
Note: Starting in API level 33, this permission has no effect. If your app accesses other apps' media files, request one or more of these permissions instead: READ_MEDIA_IMAGES, READ_MEDIA_VIDEO, READ_MEDIA_AUDIO. Learn more about the storage permissions that are associated with media files.
