Android openGL hook
hook头文件
#ifndef _GL_INTERFACETEST_H_#define _GL_INTERFACETEST_H_namespace android {void hook_eglSwapBuffers();}#endifhook实现
#include #include "egl_hook.h"namespace android {void hook_eglSwapBuffers() {ALOGD("hook successfully! eglSwapBuffer...");return;}} hook调用点
在eglApi.cpp内增加hook点
EGLBoolean eglSwapBuffers(EGLDisplay dpy, EGLSurface surface){hook_eglSwapBuffers(); return eglSwapBuffersWithDamageKHR(dpy, surface, NULL, 0);}makefile
Android.bp
cc_library_shared { name: "libEGL", defaults: ["egl_libs_defaults"], srcs: ["EGL/egl_hook.cpp", "EGL/egl_tls.cpp", "EGL/egl_cache.cpp", "EGL/egl_display.cpp", "EGL/egl_object.cpp", "EGL/egl.cpp", "EGL/eglApi.cpp", "EGL/Loader.cpp", ], shared_libs: [ "libvndksupport", "android.hardware.configstore@1.0", "android.hardware.configstore-utils", "libhidlbase", "libhidltransport", "libutils", ], static_libs: [ "libEGL_getProcAddress", "libEGL_blobCache", ], ldflags: ["-Wl,--exclude-libs=ALL"], export_include_dirs: ["EGL/include"],}其他
可以将hook封装成库调用
可以在hook库中新建线程实现某些吓死人的技术
