Could somebody help me out with this..

Its like this if you want to invoke Application2 from Application1 then you have to add one more intent filter in the Application2, you have to define an action in Application2 Manifest like
<action android:name="com.app2.intent.action.INVOKE_APP2"/>

and then define intent in your Application1 as

Intent i=new Intent("com.app2.intent.action.INVOKE_APP2");
startActivity(i);

This does the job of invoking your application
