I need to split the Android screen into two parts and run 2 applications (app A and app B) simu开发者_JAVA百科ltaneously. App A will run on screen 1 and App B will run on screen 2. Both are visible to the users. I need to implement this thing in the Android Framework. I do not know much about the android framework and this is urgent and should be done on android 2.1 Is this possible, if yes please explain the procedure to achieve this.

Thanks in advance.

Implement Application A as a ActivityGroup and run Applicatoin B inside of it.
