Pass data between android and air application

I have two applications say app1 and app2. App1 is a native android application and App2 is an android application build with adobe air. Now i am able to launch App2 from the App1 using the following intent

Intent i = Intent.parseUri("App2://arg1=value&secondArgument=someValue", Intent.URI_INTENT_SCHEME);

            i.addCategory(Intent.CATEGORY_BROWSABLE);

            i.setComponent(null);

            startActivity(i);

When the App2 is closed i want to send some data to App1 and go back to App1. So how can i do this in action script?

Could anyone suggest me a method to solve the problem?
