Android Question Make folder - Android 11

See
android.jar / targetSdkVersion / minSdkVersion | B4X Programming Forum
You need a manifest entry to use it when targeting SDK 29. It will not work at all under SDK 30.

Dear friends,

I am trying (Android 11, SDK 29/30):

B4X:

        Dim rperr As RuntimePermissions
        rperr.CheckAndRequest(rperr.PERMISSION_WRITE_EXTERNAL_STORAGE)
        wait for Activity_PermissionResult(permission As String, result As Boolean)

        Dim FileDirr As String
        FileDirr = starter.rp.GetSafeDirDefaultExternal("")
        File.MakeDir(FileDirr,"xxx1")
        File.MakeDir(FileDirr,"/yyy2")
        File.MakeDir(File.DirRootExternal ,  "/zzz3")
        File.MakeDir(File.DirRootExternal ,  "xzzz4")
        File.MakeDir(File.DirInternal ,  "xyxy5")
        File.MakeDir(File.DirInternal ,  "/zxyxy6")

but then I have no folder in sd card and I have no folder in mobile,
please, where I am doing mistake?

In manifest I am trying it with:

B4X:

AddManifestText(<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="18"/>)

and without this row. But same result..

Please for advice,
Thank you

Click to expand...

you should use the "ExternalStorage" class from May 2021 for this.

Agraham, Filippo, thank you very much

Wow, I was thinking of creating an app that would add custom notification sound files to the device so that they will appear in "My Sounds" sound picker for use in notifications of other apps on the device.

But it would require creating the folder \media\audio\notifications if it didn't already exist and then creating files in that folder.

I wonder how that would be possible with TargetSDK=30
