How to install forex robot in MT4 on android

Ok guys, the time is finally here! I have finally decided to buy a forex robot but I don't know how to install it on MT4. Yes, it came with some instructions but they are not clear enough. Has anyone done this before? I would appreciate some guidance.

Get the robot file, save the folder on your system, open MT4, go to navigator and select the robot file, let it install, then click on the smiley symbol on your toolbar to enable the robot to start trading.
