touch through translucent app
===

I have searched around and found how to create a translucent background for my android app, but so far I haven't seen anything answering how to interact with what's behind it (the home screen for example).  

For anyone who needs to know, here is what helped me make the app view translucent:

How would one go about allowing the user to interact with what's behind the translucent app?  A good example of an app that allows this is the "Transparent Screen" Android app:

Any help is much appreciated!
