Android target for a _transitive closure_ library aar

One of my work projects is an Android library with a substantial JNI footprint, designed for inclusion in third-party Android apps. I'd love to be able to specify it as a single bazel target (say for an aar, which seems to be what the Android people want us to generate these days) that depends on my android_library and cc_library.

My current planned stopgap is to build an android_binary and then take the .jar and .so out of the target for redistribution. Improvements and suggestions welcome.
