Android Question Make folder - Android 11

[petr4ppc]

Dear friends,

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

        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:

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

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.

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

ExternalStorage - Access SD cards and USB sticks

Before we start: External storage means a real sd card or a connected mass storage USB device. This class can also be used to access the secondary storage (File.DirRootExternal). This becomes relevant with newer versions of Android that restrict direct access. It has nothing to do with runtime...

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
