Diffuse

Diffuse is a tool for diffing APKs, AABs, AARs, and JARs in a way that aims to provide both a high-level view of what changes along with important detailed output.

It is meant to be used on small changes, such as those that occur in a single PR or git SHA. Here is an example of updating the Dagger library in the SDK Search app:

$ diffuse diff sdk-search-release-1.apk sdk-search-release-2.apk

OLD: sdk-search-release-1.apk (signature: V2)
NEW: sdk-search-release-2.apk (signature: V2)
