Ionic 2 runs on emulator but not in real device

I have install ionic 2 template application. On emulator application runs OK, but on actual device android 4.1.2 I see only white screen. I have try to debug app with ionic run android --consolelogs --livereload but i don't see any error.

Application should run on my real android 4.1.2 (LG-E440) device.

Steps to reproduce:

1. Follow instructions: http://ionicframework.com/docs/v2/getting-started/installation/
2. Take 4.1.2 Android and try to run application.
3. Application should show only white screen...
