title: Android compile error using buildozer
body: <p>I am trying to compile an .apk (<a href="https://github.com/tshirtman/kivy_service_osc">this one</a>) using buildozer. But I keep getting the command failed message below. I've tried using a different python path, reinstalling buildozer, using different buildozer paths, compiling from Mac HD, compiling with sudo, a different cython version. None work.</p>
