Android Question It does not work: rp.CheckAndRequest(Starter.rp.PERMISSION_READ_EXTERNAL_STORAGE)

[jose sanjuan]

Can somebody help me?

The following code does not work with sdk 33:

       Dim rp As RuntimePermissions
       rp.CheckAndRequest(rp.PERMISSION_READ_EXTERNAL_STORAGE)
        Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
        If Result=False Then
            Exitapp
        End If

Returns false, does not request permission.

Google seems intent on dumbing down Android to the point of uselessnes to me. I think of my devices as little computers and I want a proper file system on them, not the limited tortuous things that Google offers and that I don't understand, ContentChooser, FileProvider, ... o_O I'm getting old...

See API changes here

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...
