There are better ways of handling this. The purpose of an Intent is to atomically request that an action is performed (and optionally retrieve the result of that action), not to continue a discussion with the activity throughout it's continued lifetime.
There are a number of ways to do what you want, if both the calling and callee activities are in the same app (just a startActivity() type call), you could use shared preferences: http://www.androidcompetencycenter.com/2009/01/android-basics-managing-activity-states-part-ii/ If the activities are in different apps, you should use a content provider to handle the IPC: http://developer.android.com/intl/de/guide/topics/providers/content-providers.html Either approach will allow you to share the state data between your activities.
