I saw many people asking for a Tutorial about writing their own Remote Administration Tool, so I now introduce you in a basic kind of RAT. This program is not for real use, but for learning how you could write this kind of tool. It will be basicly coded and not very refined.

First, I want to give credit to the author where I first found how to do this: Astr0baby's Blog. This article was dated, so I took the script on his page and reworked it to make it work today. (I also included the way to make it hide the cmd line popup.) Requirements
The Android lock screen interface is an integral part of our everyday use.
