This guide demonstrates how to locate a target .so library’s base address on Android, compute the offset of a native method, and use the ShadowHook framework to hook the function, replacing its implementation with a stub that always returns true, complete with CMake setup and Java loading steps.
This article details three memory‑saving techniques—reducing default thread stack size, releasing a 130 MB WebView reservation, and shrinking the ART heap—implemented via system‑API hooking and the Patrons library, and evaluates their performance impact on 32‑bit Android devices.
This article explains the Android ANR workflow, analyzes the system's appNotResponding logic, and presents a robust monitoring strategy that captures SIGQUIT signals, validates true ANR events, and hooks trace writes to reliably detect and diagnose ANRs in mobile apps.
This article provides an in‑depth overview of the ELF file format, describing its headers, section and program tables, symbol structures, and demonstrates how to use this knowledge to locate and hook functions in Android native libraries such as libmedia.so.
This article explains the detailed ELF file format—including ELF header, section and program header tables, various section types, and a practical Android native hook example—helping developers understand and troubleshoot native binary loading and symbol resolution.
