So, I'm looking at cryptocurrencies again, and setup a miner for Magi, and thinking, "hey, this is a CPU coin thats supposed to be fair", I decided to take it to its logicial extreme, and see if I could get the miner to run under android (specifically my Nexus 5).
The answer?
Yup:

With some pain, I got the miner to compile against bionic and run non-rooted (currently you have to use adb to start the daemon, but writing a frontend shouldn't be hard).
Here's the device specs on CPU power:

I'm honestly not sure if this would be superuseful, but I won't mind building this into an actual APK. Figure tons of us have old Android phones that aren't in use anymore ...
