Want to start reskin !!! Some informations needed !!

Hello everybody,
Well I'm very interested in making money from the internet , so it's at least 4 months that i'm searching a lot about it and reading about making money methods such as CPA , reskin , shopify eCommerce , programming as a freelance . I'm the first year in computer science engineering so i can make programs in C and python ( i don't mean complex programs but i've the basics ) ; also i can do scripts in bash .
Hence , i decided to start reskininig apps to make some profit and gain experience after that i want to start eCommerce. The main problem i has is that persons say that nowadays (march , 2018) there is no several benefits from reskin , however others say the opposite ; i just want to know the truth about that !!!
I saw that to begin in reskin you should learn Photoshop , how to use Android studio ; so i'm asking if there is any other skills.
My last request is if someone there is reskinning app , just to say how nowadays it's going , and how much profit can you get in how much time of hard working?
Thank you very much for your answers , i'll be glad to hear from You !!

This is exactly what I was researching today. It's too bad that I need a good knowledge of photoshop and I don't have time to learn it. I have gotten over 100 source codes.

Bro i think that the main problem is how reskining apps is doing nowadays , photoshop you can learn it by searching for free or paid formations in udemy/youtube ; have you started reskin yet or not ??

wtf is reskining, i thought you getting skin transplant

i'm talking serious hhh !!!!
