Thanks for such a great job . I tried the codes and it worked very well on my computer and on android virtual compiler where when I installed the app on my android phone it woked too but didnt submet the info to the Gsheet , I mean the submetting message shows up but the "Submetted" message didnt and as a result wasnt able to send them to gsheet . Can you help me to figure out the problem ?? Thanks in advanced !

I'll suggest you to print Http response so that you'll get know about response coming.

thanks for your response , but as ı still new at programming I would ask you to give m a hint for that

For step by step guide, please read article on it which is written by me. It's available on repository main page (README.md)
