Android Version

I had created a simple project with mysql connectivity. But i am new to ionic when i build and run my app in android old version it works perfect but in latest version it doesnt show database.

Do you connect to database through internet?

Yah connected it working in the android version below 8

From android 9 non-secure connections not allowed by default. You can add cleartextTrafficPermitted="true" property to android manifest file.
For next time use chrome inspector, it show this error in console.
