I was trying to implement Samsung's MultiWindow support in an Android app, and I haven't been able to find the drag and drop feature between MultiWindows that was available in Samsung's S Pen SDK 2.3.
Latest SDK for Pen is 4.0.7 and for MultiWindow is 1.2.6: in both cases drag and drop support seems to have vanished - and previous SDK versions cannot be found anywhere.
So, is there any way to support drag and drop between MultiWindows or it is not possible now?
Samsung has not included the feature in the latest SDKs mostly due to performance issues that they may have noticed. I found a similar thread on the Developers Site:
I would suggest you to use Android's Drag&Drop listeners to implement the same which is pretty similar to how it was done in the older SDK's.
Hope this helps!
