[Anonymous]

I am doing a project in android. I made a app in which a floatingActionButton is not working when clicked. Its showing App keeps stopping. When i click the button the setOnClickListener works and the desired page is shown but then a dialog box appears that says " APP keeps stopping".

Github project link: https://github.com/Xander1540/Xold[enter link description here]1

Here the floatingActionButton named sellFab when triggered works but then the app stops responding.
