Identify the backend first
The IL2CPP documentation explains the ahead-of-time conversion path. Inspect package contents and build metadata where available instead of assuming all C# code remains as readable managed assemblies.
| Material | What it may reveal |
|---|---|
| Android DEX | Java/Kotlin wrapper and plugin code |
| Managed assemblies | Compiled managed logic when present |
| IL2CPP/native libraries | Native compiled application/runtime material |
| Assets and serialized data | Packaged content, often transformed |
JADX is useful for Android DEX, not a universal Unity C# project recovery tool.
Account for stripping and optimization
Managed stripping can remove unreachable code. Native compilation and optimization further change source-level structure.
Original comments, editor-only scripts, source asset files, scene authoring context and repository history may not be present in the distributed package.
Keep the purpose authorized
Analyze your own app, a permitted security review or another lawful scope. Do not bypass licensing, impersonate a publisher or redistribute extracted proprietary assets.
For source recovery, search backups, version control and CI artifacts first. They preserve information that compilation intentionally discards.
Record recoverability honestly
Distinguish an extracted texture, a decompiled managed method and an inferred native routine. Avoid calling the collection “the original project” unless it actually contains the original maintained source and configuration.
Use APKLint as an inventory aid
The Unity APK Analyzer can help identify engine-related files, backend clues and native architecture entries. It does not convert arbitrary IL2CPP output into a complete editable Unity project. Use its findings to choose an authorized analysis path and state the missing material explicitly.
