Installation of Native Libraries

An Android .apk file can contain native libraries for one or more architectures. Historically, all native libraries for the target device are extracted at .apk installation time. This would result in two copies of native libraries on the target device: a set of native libraries which are stored compressed within the .apk, and a separate set of native libraries on the Android target filesystem.

Starting with Android v6.0 (API-23), Android added an ability for
