Cut phone screen on two parts that do simultaneously two things

Question

Can i create a program which will cut phone screen on two parts.

Those two screen will do simultaneously two things, for example to watch a clip and to read and write sms.

I think that: 1) i need to create a home luncher application first. How can I create a custom home-screen replacement application for Android?

2) Then i can start two fragment in my activity. http://developer.android.com/guide/components/fragments.html

3) Finaly i open app1 in first fragment and app 2 in second fragment. Can i do that, open an application in a fragment?

Any other ideas will be usefull.

Answer 1

I think you need a modified version of the Android ROM to be able to do this. With the standard ROM you can only have 1 application running in foreground at any given time.

Samsung has done something similar on the Galaxy Note by allowing you to watch video while doing other things.

If you don't want to change the ROM you could implement this on your own apps, but not on all the apps.
