Q:

How to add Facebook dependency in offline mode on Android Studio

I am trying to write a program that can make Facebook updates but i have issues adding the Facebook dependency.  I already have the sdk but couldn't add to my project because... 
even though i have tried adding the gradle.prperties file to the extracted Facebook folder as a comment suggested here
Next i tried adding as suggested on the Facebook official page but i hit this snag...
Now, because if the price of data where I'm from, I'd rather not go online since I already have the sdk locally so my question is how can i manually cache the sdk into my project? 
EDIT: For clarity, my question is HOW DO I ADD THE FACEBOOK SDK INTO MY PROJECT WITHOUT GOING ONLINE (i.e. OFFLINE BUILD)? 

A:

Download Facebook Android SDK 4.24.0 ARR it from here
Then,
In order to import a .aar library:

Add a .aar file in libs folder. 
Use "New Module" option under File menu. 
Import the .aar file. 
Build gradle and compile the project.
