White screen on Android


I do have the same problem since I began to learn Ionic: starting with a very simple app, with not even a modification inside after app creation, I’m not able to see the application under any android emulator, I always get a white screen.

Debug with chrome inspect is fine except an error with core.es5.js.map/android_asset/www/build GET failed net::ERR_FILE (Request URL:file:///android_asset/www/build/core.es5.js.map)

I can use whatever template, I always get the same white screen problem.

If I deploy my application ionic 2 on android, it is all white
