Following a visitor's comment, i've tried the Android port of Embla yesterday without much luck.
The engine is written and maintained by Folkert van Heusden and various builds of Embla reside in his HOMEPAGE.
The Android build is compiled by Aart Bik according to the website. It targets arm5 and installs fine.
However, despite many efforts by other users as well as myself, there are issues:
* Takes all threads or just one after importing into Chess for Android,
* Hangs during Fischer clock games with black, no move with white,
* Plays fine vs human player using fixed time per move, but only with black.
You may download Embla for Android HERE and try for yourself if you're patient enough. Any clue about the issues will be welcome.
