About

Goal of this project is to use Android Binder at Linux desktop environment. The most of source code was come from Android Source Repositories(Android 14). But, the source code was modified slightly for Linux dekstop.

Prerequisites to build & run

3. libselinux and libsepol must be installed. http://userspace.selinuxproject.org/
4. 'libc++' and 'fmt' must be installed too.
5. CMake is used as a build system.
