"ant release" with ANDROID_SDK_PLATFORM set fails

Trying to generate a release that fully includes android support fails.

$ ANDROID_SDK_PLATFORM=<parentdir-of-android.jar>
$ export ANDROID_SDK_PLATFORM
$ ant release
... failures compiling android/topology/...

and these jars aren't built:
target/android/android/topology/lib/edgent.android.topology.jar
target/android/android/hardware/lib/edgent.android.hardware.jar

android/topology/build.xml is missing the edgent.api.oplet.jar in the classpath (presumably missing since some other refactoring happened)

classes in android/

have imports lacking the "org.apache" prefix (missing since the quarks->org.apache.edgent rename)
