I need some help with my android app.
My app uses a php file to connect to MySQL database and do some CRUD operations. It was working fine on all mobile phones but suddenely it stoped working on some phones. After searching for the problem reasons I noticed that all phones not working updated to android 9 and I tested my app on new phones with android 9 and the same problem found.
My app is connecting to php file and MySQL database on wampserver on my lap.
I have updated android studio build tools to android 9.
Any suggestions to solve this problem?
