Could this be adapted to our Kobo Android ?

Probably we can, but not without changes. It looks like it is wrapper for Nook system library we don't have.
What we have is libepd.so library and after decompilation of Tolino software I have found first usage of it. The app in the attachments shows how to do full area refresh from your app. If you want to write your app and have nice, smart refreshes and always clean display - you can use it
We can also modify existing apps (like Moon+ Reader) and add needed calls to improve image quality (through decompiling, adding needed calls in smali). It's not s-f. It's doable. Someone did it for AlReader (you can find it on lesen.net Tolino forum, modified version is installed in my image posted here). It's easier for open source apps, of course. Generally it's fantastic that we can improve user experience on Kobo (and Tolino, hehe) devices. I'm now certain that Android is the best OS for Kobo readers
If you look closer into ScreenHelper class, there are screen refresh methods like A2, DU, GC16_PARTIAL, GC16_FULL etc. so we have the same update modes like Nook. A2 is for fast and no ghosting 1-bit black&white displays. We can turn on this mode for games and movies (but additional dithering implementation would be very desirable).
Have a good fun!
