Simple android App working on browser(ionic serve) but not on device and emulator

I followed the ionic starter and created a simple app.
When I am trying ionic serve app opens in browser and I am to see the home and list of items.
When I am trying ionic cordova build android , build get success and apk gets created inside platforms/android/… path.
After installing this apk on an android emulator or device, when I opens the app, it crashes and android shows Open again popup message.

I do not know what is the problem here. Please help.
