Object Interaction between Dual window Applications
If the application can be run as a Split window in Dual window mode, object interactions between the two Split windows will be a very useful feature for users. One typical example of object interactions is the drag-and-drop operation to move objects. This feature can be implemented in your application, i.e., you can implement dragging something from one Split window and dropping it into the other Split window. This can be developed using Android APIs in the same way as the drag-and-drop operation for an Activity.
This section explains how to implement the drag-and-drop operation between two Split windows in Dual window mode for LG smartphones. For drag-and-drop operation, implement the drag operation on the sender side, and implement the drop operation on the receiver side.
