Porting an SDL 2.0 game to Android

Question

I have a game written in C/C++ with SDL 2.0, I would like to port it to mobile platforms (specifically Android and maybe other platforms too). I read SDL has a native support for Android but the game itself is written for Windows at first, although no Windows-dependent libraries/code were used. As for Android, I only used the Java based SDK before and never integrated it with native code. Which changes (if any) do I have to make to the C/C++ so I could use it on Android platform? How exactly do I acually compile the whole thing to an APK? Is it possible to use Java and C/C++ for the application, I mean, the game's activity will be the native one but the other activities (menus, settings, etc) can be written with the regular Android Java SDK?

The Android README file in the SDL source release outlines most of what you need to know with regards to porting your SDL App to Android. There's also an example project for Eclipse that demonstrates you can modify to suit your needs.

The iOS README file is also useful, namely for the sections on events and input, as much of it carries over to the Android port.
