thanks Erel but when I ran "pdfgen" I mean this one "[B4X] PDF Generator - B4X Cross Platform - Class 100% B4X Code" B4A gave me an error according to this message :

My guess is that you are not using latest version of B4A with latest version of Android SDK. Carefully follow these instructions: https://www.b4x.com/b4a.html
