I want to become an entrepreneur, which language suits my purpose?

First and foremost, i would like to say that i am already learning HTML and css. I realize that these are not programming languages, but one of the first things i want to do this year is learn to write up my own website from scratch. After that, i would like to launch it.

I want to develop android apps, as well as learn a proper programming language that would make me valuable to employers, so when the tough times come, i have a plan of action, as well as something that would be feasible for me to learn. I realize that android apps are coded with java, but would this be something that i could learn as my first programming language? I want to learn anything that will give me a source of income, as well as give me the ability to create my own.

I thank anyone that takes the time to guide me, as well as clarify me if i am misguided in any way.
