Hi Sven, you are right. I want to display two activities from different apps on the screen simultaneously. I know it can't run more than one activity at the same time, but I want to achieve this. I have some ideas: 1. Change the scale of application into smaller size. 2. Modify the framework to activate another activity from another application. However, I am not sure how much effort should I pay on the second step. Would you have some ideas to share with me?
