I have an old smartphone (Samsung Galaxy S2), unlocked, and I'm thinking of trying to write simple apps for it on my Fedora-24 laptop.
I'm fairly familiar with Java (and Eclipse) (Long ago I wrote a program modifying TeX web2c to output Java).
I haven't found a reasonably authoritative article on this, and would welcome advice and/or suggestions from anyone who has gone down this route.
I ran "dnf search android" and found quite a few appropriate sounding programs, but found it hard to tell how they would fit together.
I'd like to do it in as simple and standard a way as possible, eg not writing in C++ and using a program to translate that to Java. I've looked at a number of sites claiming to teach this topic, but none of the ones I have seen had concrete instructions of how to transfer Hallo World, say, to the phone and run it there. And all seemed to have their own special programs, eg I was just looking at one which said "Android Studio is the official IDE for Android development" but none of the others mentioned this program (or suite).
As I said, I would be very grateful for any knowledgeable adivice on this topic.
