Hello, Abdulizor, is like your zip file is not well packaged before uploading it. Content can not be unzipped without error. At moment, it is unusable! I will suggest:
You use line #6 on top of the code in the B4XMainPage module to repackage your files.
When you hover over the line with the Ctrl key pressed, the link is highlighted in blue.
Thank you for this nice work and interest to share in advance
