Android Question How can i get “All files access” or “Permanent and complete access to a folder” in android 10-11 (Scoped Storage)

[rasul.g]

Any sample please

Can all apps get "All files access"? (like apk files non-shared and out of play store?)

for access a folder should i use "ACTION_OPEN_DOCUMENT_TREE" ?

and after getting "All files access" or "Access to a external storage folder" can i use file address like this

File.Combine(File.DirRootExternal,"mySelectedfolderOrAppFolder/subfolder/file.zip")
SQL1.Initialize(File.DirRootExternal, "folder/backup.db")

or

File.ListFiles()
File.Copy()

and other File methods...?

what about android 10 ? should i use just android:requestLegacyExternalStorage="true" in manifest and its fine?


please any help. I'm not familiar with Java codes and I don't have Android 11 emulator

See targetSdkVersion 29 implications: https://www.b4x.com/android/forum/threads/android-jar-targetsdkversion-minsdkversion.87610/#content

The best solution is to avoid using File.DirRootExternal. Switch to RP.GetSafeDirDefaultExternal.
The other option is to set requestLegacyExternalStorage. This will work for now.
Eventually you will need to switch to ExternalStorage and let the user choose the folder.
