This is great! I hope some of this work goes towards building a good free android sdk for debian. Last time I checked, the debian sdk was stuck on a really old android version, and the android rebuilds project relied on prebuilt compilers from google (hello ken thompson attack).

Speaking of, how do they deal with java dependencies? Last I checked gradle there was simply no way to tell it to build things from source, instead pulling hundreds of prebuilt java binaries, with native libraries and all.
