How easy it is to earn from android game development?

Question

I have heard that one can easily earn at last ₹ 30000 per month. And how long it takes to learn android for a beginner. And Is it necessary to learn whole java or just little bit knowledge is enough.

Answer 1

what matters is just knowledge and experience....you should know thay flappy bird was developed in just three days....ref.Wikipedia

Answer 2

For game development, just the basics won't be enough.

Answer 3

You have to find the hole in the markt or something people really should like (which is not easy). Like flappy bird, it was a very simple game and it became very popular.
I heard that making games isn't that easy, so if you want to make a really good game than you have to be really good at making it to.
