Most efficient way to develop without browser?

I am working on a mobile app that uses the native maps, therefore, I can’t troubleshoot from the browser. I was wondering if there is a quicker way to develop because right now I have to make a small change in my code and then wait 2 minutes for the emulator to open. Is there a way to have the emulator auto update or anything?


(He is referring to the --livereload option)
