How to apply in real time the change of appcelerator application

I'm new builder of appcelerator studio, so I'm building a simple app and I test it throught my Android device, so if I try to build the code, running (in debug mode) on my device, this works, but if I try to change the code for examle:

I have write a wrong description:

$.label.text="Okkk"

and I change when the debug is running in this:

$.label.text="OK"

to see this change I must stop running debug, rebuild the application.

This is the best way or there is another mode then if I change the code, it in real time are rebuilding in my device?

Solution

Before you build an app, Click on 'Enable Liveview' icon from the Studio top toolbar. This will do the magic for you.
