Hi Michael, you certainly can't "modify the framework"... I mean, of course you can check out the sources of the Android framework and modify them but then your application would only run on devices where *your* version of the framework is installed. I don't think you want that.
What do you want to archive? Do you want to display two activities from different apps on the screen simultaneously? Or are the activities part of your application? If latter is the case, why don't you adjust your app so that it displays all the data you want on one activity?
