Intranet access from native android build

Hello guys,
i am new to ionic I have some knowledge in creataing application using rest API api available in remote server but
It is possible to create intranet crud application, the API available in server system , API accessed via particular iP, everything works fine when I produce ionic serve but after build my phone is connected to the same intranet but data not shown why?

Did you remote debug the problem on the device already?
Follow these instructions here to debug the problem in Safari dev tools: https://ionic.zone/debug/remote-debug-your-app#ios
Follow these instructions here to debug the problem in Chrome dev tools: https://ionic.zone/debug/remote-debug-your-app#android
Look at the console and network tabs for errors.

Tnx for the quickest replay sir but I have a doubt after converting to apk does console works

Yes, see the links I posted. It explains how to access it.
