You can get APK here [1]. It will crash on the first launch, since
image file isn't there.  You need to copy RISC.img
to /sdcard/Android/data/com.riscoberon.emu/files (or similar data app
directory on external storage) and then it should work.

There are few issues with it:
- touching screen will result in left mouse button click
- connected mouse didn't quite work for me (middle button didn't do
  anything at all and right button crashed application)
- size of window is scaled down - even on tablet with 1024x600
  resolution, it is small
- would be nice to have smaller image (few megabytes?), so it could be
  distributed along with package

So it isn't fully usable/functional (to be honest you can't do much at
the moment), but it works with very minor changes.  I'm not sure if I
want to continue with this any further (this would require fiddling
with SDL2 APIs for touch screen and so on). Bellow I'm providing
instruction for building this emulator for Android.

Because spam filter doesn't seem to like messages with many links
(original message was rejected), you can find instructions for building
APK here [2] (including patch for emulator).
