Hello EDMT, I know I am troubling you with my problem, but I have found a very strange thing in my problem. When I click on img_detail of other snacks, it does not crash. But when I click img_detail of Pizza, the app crashes. I check it in Pasta, but it works fine, but Add On does not expand. What could be the issue?
Hello EDMT, I checked your videos again and again, but I still cannot find the issue. Could you please tell me how to resolve step by step?
Hello EDMT, I have a problem. The app is crashing when I click on the img_detail. The error is
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.game.adarsh.myrestaurant.Model.User.getUserPhone()' on a null object reference

Please help me.
Sir see iin min 38:36 in medium + addon cost 32 and large cost 28 is bug 🙁
Hi again. After watching tutorials 7-8-9 again and again and re-doing them all over again I still get the same errors:

The error only appears when I click on PIZZA DETAILS and it is caused from the ADDON which can not load and it crashes the app
This time I used a saved file from completed and working tutorial 6 and wrote all the code again to make sure I didn't do anything wrong… but I still have the error
If anyone can send me here the working code from his files… I would really appreciate it… or someone tell me what code to add and where… even better if you can send me a picture of it
Thank you
