Android Question B4XPage

[Sergey_New]

I started using B4XPage and ran into a problem creating an application folder on my phone.

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
    rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)
    Wait For B4XPage_PermissionResult(permission As String, Result As Boolean)
    Log(Result)
    File.MakeDir(File.DirRootExternal, "test")
End Sub

There is permission in the manifest.
The folder was not created.

What is your TargetSDK in manifest?
Private app or for Google play?

What is your TargetSDK in manifest?

<uses-sdk android:minSdkVersion="14" android:targetSdkVersion="29"/>

Private app

Try setting it to 26.
Anyway the problem it's not related to B4XPages.

Try lowering to 26

I tried it, the folder appeared. It’s strange, it works on B4A on version 29. What needs to be done so as not to downgrade the version?

You can try adding this to Manifest

SetApplicationAttribute(android:requestLegacyExternalStorage, true)

Here you can see all the limits and changes that Google added version by version

Thanks, it works with version 29, but no higher.
