In a previous thread I ended up solving a File.ListFiles problem under API 29 by adding
to my manifest editor.
Erel's recommendation, as stated in https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/ , is
B4X:
SetApplicationAttribute(android:requestLegacyExternalStorage, true)

So what's the best way to handle downloaded files that arrive in the /Download folder (via emails, Google Drive downloads, etc) in API 30, which at some point we'll be forced to use? API 30 will not recognize "requestLegacyExternalStorage." As I encountered in my previous thread, not having that manifest option will cause non-media files (like KML files) to be invisible in File.ListFiles. How then would we access those files so that we could move them to File.DirInternal or RuntimePermissions.GetSafeDirDefaultExternal?It will not work with targetSdkVersion=30. Avoid using File.DirRootExternal. Either use File.DirInternal or RuntimePermissions.GetSafeDirDefaultExternal.
