Will adding code as library increase the size of the App

Question

I have an Android App named A. I create a new copy B with the same functionality but different package name. The difference between both the apps will be usage of different AD Network.

I divide my Code into different libraries and upload them to online repository, so that I can simply change the code in both the app by simply changing a single line in both the apps Gradel file.
Instead of manually changing the code for both the apps.

For Eg-

A has three features X,Y,Z

B has two features X,Y.

Now if there is some issue in X feature I will have to change the code for X in both A and B but if I plan to divide them into library I will have to change the code only once and update the A and B apps with the new libraries.

But will using this kind of setup will it increase the size of the app, OR will it be the same as if I use the code manually.

EDIT: Is there any other dis-advantage for adding code as library?

Hard to tell,but yes in general adding libraries to app increase the size of the app ofcourse, but in your case it's definitly a good apraoch in favour of code refactoring, and i don't see any inconveniences of using a library — Benkerroum Mohamed, Apr 02 '18 at 07:44
@B.M Thank you very much for the answer. But can you please tell the comparative ratio of increase in the size. — Rajesh K, Apr 02 '18 at 07:55
If it helps, AppCompat support library increase the size of the app by almost 1M ,but it contains a lot of drawables and ressources, — Benkerroum Mohamed, Apr 02 '18 at 08:17
@B.M Thanks. But is it possible that I add the AppCmpact library in my main app only and don't add it to the library? Also can you please post an answer for me to accept. — Rajesh K, Apr 02 '18 at 08:22
Yes it's actually better if you add it on the main app, since you won't need it on your library — Benkerroum Mohamed, Apr 02 '18 at 08:29
