White screen on cordova run android -l

Does anyone knows why I get white screen when using this comand in terminal:
ionic cordova run android -l

When i run that comand with ionic installation like this:
ionic start myApp super --type=ionic-angular
then my aplication starts OK.

But when I run it with comand: ionic cordova run android -l in my emulator with version installed like this:
ionic start myApp
then it shows a white screen…
