Android Question Storage on Android 4.4

[Spright]

Hi I got a problem with getting this library to work on my old Kitkat tablet (a Huawei Mediapad).

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...

I use the External Storage Browser example and the example works on my Android 7.0 phone and everything newer but not on this 4.4 tablet, is there a way to get it to support older devices too? The example produce no error but nothing happens as you press the button?

In the log it prints out:

onActivtiyResult wi is null
Activtiy(main) Resume ""
Activtiy(main) Pause, Userclosed = "false"

ExternalStorage is supported by Android 5+. Android 4 devices are very old and rare. Better to ignore them.

You don´t need the class on such old Android.
Declare the permission in the Manifest, request permission for external storage (runtimepermissions) at runtime and access the files.

Thanks. I don't have money to get a new tablet also I love to develop on it so I'm trying to get the code to work on it.
I have never used external files without this class so I'm clueless on how to implement the details. I thought runtime-permissions needed Android 6 or higher.

Here, I got some help from the forum and solved it. I can't remember if I had to edited a few lines so should include the zip in case others have the same problem. It will give some red text I'm not sure why it gives such warnings but this code works in both 7.0 and 4.4 perfectly.

I don't have the red warnings available right now as text, but I will include a screenshot for as a quick reference.
