The emulator appears, but the myApp app is not there. App does appear in iOS emulator.

consider using genymotion as your android emulator, this is better and faster. Once installed and a device of your choice has been setup use ionic run android as opposed to ionic emulate android

I’ve used this emulator successfully in building native apps, so what could be the problem? If I wanted to try another emulator without changing to Genymotion, how would I do it?
