There's no Android version, nor are there plans for one.
This and the Raspberry Pi are similar in that people keep thinking it ought to work, but the hardware is just too underpowered. By the time you get enough hardware capability to make it work, you're also running an operating system on that hardware that OBS already supports.
People have tried it on the Raspberry Pi before, including myself - download the source code and build it on the Pi - and the results are always the same. The new Pi 5, that few people have yet, is a huge jump in performance, so it might be different, but its real-world test hasn't happened yet.
