Do you want to monitor/control your BOINC android devices via BOINCtasks, like you do with all your other machines? Years ago, there used to be a 3rd party boinc client for android, that would allow remote RPC, but that stopped working with a later version of android and was never updated. Now you can do it again. And it's from the same people that created BOINCtasks.

It's working like a champ for me. My android device is listed right there along with all my other win/linux/osx machines. There is also a setting that allows you to choose from several different versions of the boinc client. Sweet.

Note: to get this to work for me, I had to turn off secure password for the client. I am behind a NAT router, so not concerned. I assume this will be working in the non-beta release of the client.
