Berkeley released Android version of BOINC 7.2.39 which now supports x86 processors. Since more devices and virtual machines may start using Android as a platform, it would be nice to have a working app.
AMD will be adding ARM processors to Opterons http://www.amd.com/us/press-releases/Pages/amd-to-accelerate-2014jan28.aspx in servers soon that will also support 64bit. It is only a matter of time before there is a 64 bit version of Android. Many may find this as an attractive option over other Linux installs. BOINC updates much easier in Android and can do so automatically.
I currently have Android 4.2 in a VM for testing and can confirm BOINC installed just fine as intended.
