01
Android APK analysis
Review the manifest, Java and Kotlin code, native modules, permissions, storage, network traffic, WebView usage, and component calls to trace behavior and identify risks.
Android APK / SDK / Desktop apps
Reverse Engineering
Understand how an Android APK, mobile SDK, or desktop application works. I trace module boundaries, key calls, and data flows to identify security, compatibility, and engineering risks.

What the review covers
02
Mobile SDK analysis
Trace initialization, public APIs, dependencies, data flow, threading, and performance to identify integration risks, privacy boundaries, and version compatibility issues.
03
Desktop application analysis
Review Windows, macOS, and Linux installers, binaries, module resources, local configuration, interprocess communication, network protocols, and key application flows.
02 / Deliverables
Findings you can verify
A clear explanation of the application's purpose, architecture, main technologies, and most important findings.
The main modules, third-party components, native libraries, and how they depend on one another.
Startup, initialization, key calls, local storage, and network paths, with diagrams where they help.
Code locations, configuration, call chains, or observed behavior behind each finding, with verified facts and open questions called out separately.
Security, compatibility, performance, and engineering risks ranked by impact, with practical follow-up steps.
What the analysis covered, the limits of the available tools and evidence, and what needs a runtime environment or an additional sample.
03 / Process
Start with the question you need answered
01
Describe the request
Share the analysis target, platform, issue, and the specific question you want the review to answer.
02
Agree on scope
Define the depth of the review, deliverables, estimated timeline, and the scope of static and runtime verification.
03
Analyze and verify
Collect evidence, reconstruct the relevant flow, cross-check findings, and flag discoveries that could affect the scope.
04
Review the findings
Walk through the report, evidence, and limitations so you can choose the next fix or verification step.
04 / Case study
Tracing a public SDK through verifiable evidence
Independent technical research · 2026-11-02
Tracing Android SDK event and attribution flows
This study examined the officially released RangersAppLog Lite-cn 6.17.13 artifact, tracing event entry points, local storage and batch sending, plus the client flows for deep links and deferred attribution.
- 01Verify the artifact
Check Maven provenance, version, checksums, Manifest and dependencies.
- 02Trace the calls
Follow AppLog through the instance, event queue, SQLite and batch sender.
- 03Cross-check the output
Compare JADX and CFR, using javap to review decompilation problem areas.
- 04Index the evidence
Document versions, main flow diagrams, evidence and open verification tasks.
The questions
How do events enter the queue, reach local storage and get sent? Which requests and callbacks belong to the attribution client, and which decisions happen on the server?
A key research decision
The released AAR and the official open-source reference have different versions. Their provenance was recorded separately and the relevant flows were cross-checked.
The result
The study linked the main static call paths to traceable code evidence, recording confirmed paths, inferences and areas that require a running environment.
Relevant engineering experience
Work on mobile ad SDK integration, performance, stability and production diagnosis informs which entry points and data flows to inspect first. View the engineering background.
Verification scopeThis is static research on a public artifact. Actual device collection, request payloads and server attribution outcomes still require dynamic verification.
