1) Download and install the APK. Depending on the device you are using, you will need to install the APK using omp postfix if you have multi-core device. If you have a single-core Android device, or you're having problems with omp version, you'll need to use noomp to install it.
2) Install the latest Xash3D Android ( Download here from GitHub )
3) Copy cstrike and valve folders from your Steam CS1.6 installation to the xash folder on your SDCard
4) Run CS16Client and have fun!
Important Note: Delete any PAK files with name starting with "touch" or "vgui" in cstrike folder.
