Right now I'm storing a SHA1 in a folder in /sdcard since that seems likely to work on non-rooted devices, but I haven't tested it. This cuts build times from 6.5 seconds to 1.5 seconds for me. You can save another 0.5sec by passing the --no_install flag to avoid the SHA1 check altogether if you're sure that nothing has changed.
