Diffusing Changes in your APK
summary
Tool Diffuse compares two APKs and produces file-level diffs with compressed and uncompressed sizes, per-Dex counts for methods types fields and strings, and resource config diffs. It identifies concrete surprises: upgrading a codegen dependency removes ~900 strings and saves ~75 KB, bumping minSdk 23→24 signature change drops a signing scheme and lets R8 remove two backported types, recompressing ARSC can save ~134 KB transfer but add ~201 KB install cost. Supports APK AAB AAR JAR and emits lint-like alerts.
