Kivy as a touch based UI library is very nice and the cross capability is awesome. Actually building production artifacts with buildozer is painful. Last time (admittedly 2 years ago) I did it I had to trick it into using a newer NDK because the play store required it but buildozer wasn't up to date enough to recognize the new NDK. Getting it to sign an apk was undocumented and required finding the right magical mailing list response. But I can't put all the blame on buildozer. They seem like they're actually trying to abstract away all the pain of building native apps for android.
