"""Removes the resources from a resource APK for incremental deployment.
The reason this utility exists is that the only way we can build a binary
AndroidManifest.xml is by invoking aapt, which builds a whole resource .apk.
Thus, in order to build the AndroidManifest.xml for an incremental .apk, we
invoke aapt, then extract AndroidManifest.xml from its output.
