Multi window feature in android

Question

Currently only sumsung is providing multi window feature. Why others vendors can't.?

Is there any hardware dependency.?

If I want to write multi window feature for my goggle nexus how can I start.? Any tutorial or link from where I can start.

Answer 1

If you will check out at SAMSUNG Developers packages are of two types :

Type 1 : Implemented in the Android API.

Type 2 : Implemented in the Android Framework.

You can see there MultiWindow is of package Type 2. This means for MultiWindow support SAMSUNG have heavily modified the Android Framework. So until and unless there is no vendor support you can not develope applications using MultiWindow feature for that vendor.
