Ionic run is working but apk(after ionic build) is not working

My project is working fine when I run using command ionic cordova run --device android. And I generated apk for the same using command ionic cordova build android --prod. When I open app it’s showing blank page. I was trying to debug same using chrome devtools and found that none of the resources is getting loaded.

What does the console show?
What is the response to that request?
