Yudun goes beyond DEX. Resources, signing identity, repackaging checks, upgrades, and channel outputs stay in one delivery chain so a build does not pass installation only to fail its real release path.
Reduce the readable surface of critical code and sensitive resources with protection chosen for the business risk.
Validate signing identity, package integrity, and the server's approved-version policy together.
Test fresh install, in-place upgrade, channel modification, and final package identity on the APK that will ship.
This redacted static assessment reviewed the APK as a whole instead of using a single decompiler screenshot as the result.
Read the seven evidence pointsScope: The public result is a candidate-level static assessment; device runtime, performance, server receipts, and rollout still require validation.
Provide the original APK, signing and version plan, and any changes made by channel tooling.
Handle DEX, resources, Native containers, and integrity separately, then create a traceable candidate.
Check signing, upgrade, launch, and critical flows on the final channel output.
Clarifies the distinctions between current signature consistency, official publisher identity, overlay upgrades, channel artifacts, and server-side version policies, while defining governance gates for repackaging.
No. Resources, manifest data, native libraries, signing, and version upgrades also shape repackaging and release risk.
No. Installation only means the system accepted the package. It does not prove that signing identity, server version checks, or business integrity remain valid.
It depends on what the channel tooling changes. Fix one build order, then verify signing, resources, application launch, and upgrade behavior on every final output.
Record build source, version, signing certificate digest, file digest, and regression result, and let release tooling accept only that identity.
