Help! my ionic Android app not rendering properly in emulators and real device

Good afternoon guys, have been facing this issue for some time now, though still a beginner/learner. Am currently developing a ionic application with visual 2015. Everything has been going on fine including the output (using ripple with google chrome). I then packed the app into a (.apk file) for testing on real android device, but to my surprise, the application displays a blank header with an empty content. I then decided to test it on genny motion emulator, the problem is the same as real device. The tabs together with content is empty. Don’t know the reason for this, please someone should put me through what might be the likely issue…Thanks in advance, below is the screenshot of the empty contentimage
