I have created a debug apk file and installed it on my phone. The app is installed successfully and opened. But the courses are not showing in apk file. But when I run 'ionic serve' the courses are showing. I have given the URL and app id in config.ts file. But in apk the courses are not showing. The homepage is coming blank.
I have created the apk using the command 'ionic cordova build --debug android' and also i tried to create from android studio. But both lead to the same issue.
