Hello!

Currently, I became interested in TEE research and development. After small investigation, I found out your product: OP-TEE. After reading about it, there is a thing that still bothers me: is it possible to create an application which uses OP-TEE and distribute in via Google Play?

For OP-TEE you typically create a pair of binaries, one binary running on non-secure side (plain Linux environment) and one binary (Trusted Application) running on the secure side.

Google Play hosts applications running in non-secure world, so I'd believe that distributing the non-secure side of your feature using Google Play is something you can do. But for the secure side, it's not that easy, since it's usually the OEM that decide what to install and is allowed to run on the secure side on their devices.
