I am trying to implement an input plug-in for Xperia touch controls in one of my projects. The only way to get this input is through a NativeActivity, but I don't want to rewrite my entire project to use a NativeActivity. Instead, I would like to run the NativeActivity on top of the existing Activity (sending thorough touch and key events), without hiding the existing Activity. Is there a command that I could stick somewhere in the onCreate() or the Intent, or whatever that can achieve this? Let me know if you need a better explanation or some code to better describe what I'm after.
