Apk for ionic app, build from ionic package is not hitting any external APIs

I created an APK file from ionic package (used command - ionic package build android in the terminal ), but the APK is not working in mobile device as there is no hit going to external APIs and there are no logs on the server. But when i am trying the same using chrome debugger (used command - ionic serve in the terminal ) i am getting success response from same APIs and logs are also as expected.

Not sure what is the issue.
