The built JAR file provided in the root of this enlistment embeds instead of references Google's android-support-v4 library (as opposed to the earlier released android-binding-v30-0.52.jar which does not). This difference makes it difficult to build a project that references both the android-bindings JAR and the app compat library (com.android.support:appcompat-v7) due to duplicate errors raised during DEX-ing. BTW, I noticed that the ".fatjar" file under androidbindingv30 does attempt to exclude android-support-v4:
excludes=<jar|android-support-v4.jar>;<jar|annotations.jar>
but for some reason this didn't seem to stick...
Could you update the published binary to not include the external bits?
