In the ecosystem of Android reverse engineering, the resources.arsc file is a critical component of any APK (Android Package Kit). This compiled binary file contains the application’s resource table—a map linking resource IDs (e.g., 0x7F01002B) to actual resource names, types, and values (strings, dimensions, colors, layouts, etc.).
