[Android] Apps can be tapjacked

-

Android security issue:
All views (e.g. GLSurfaceView) in the UnityPlayerActivity should have .setFilterTouchesWhenObscured(true) set, otherwise an attacker application can invisibly record all touch input to the Unity application without the user knowing.

How to reproduce:
1. Open QA attached project
2. Build to device
3. Start android studio project and run it
4. In the built app press start (It will launch the unity project)
5. Click on the droids on the app

Expected result: The input is registered on top layer
Actual result: The touches pass through the android “Toast” window, and go to the unity app

    You can find a lot of the well-detailed and well-written information about it at https://clipboardwindows10.com/ so let me know if you are glad of reading something like that. I would like to share all my best resources with you!

    Here is an explanation on tapjacking https://blog.devknox.io/tapjacking-android-prevent/

    It happened with me when I was trying to download this very old game Pocket Tanks from https://www.pockettanks.org I am not sure if the application that I download from their caused it or there were other miscellaneous apps in my phone.

    This was probably due screen overlays that were created. I am now trying to reproduce the same issue on Note 4.
