  • Xposed-Style Method Hook
  • Modify the inheritance relationship between classes at runtime
  • Modifies the class to which the object belongs at runtime
  • bypass Hidden API Policy

Darwin/Linux Platforms

  • Internal symbol resolver
  • Native Hook

IOS Restrictions

InlineHook on IOS is only usable in debug compile mode on non-jailbreak devices. Release compilation mode will not work properly.

To solve this problem,Whale will provide a new core named Binary Static Inline Hook.

Binary Static Inline Hook will open source in the near future.

For pcrel instruction, Whale will convert it to pc-independent instruction, If the Hook procedure have not convert instructions, please feedback to issue.

About Jit

Whale has a built-in Jit Engine, When you have more advanced Hook requirements, you can directly generate executable instructions in memory through the Jit. There is no longer the need to generate ugly hard code through tools as before.


We have pre-built binary versions of Android & IOS. You can find them in the built directory.

Whale uses CMake to build projects, so you need to install CMake on your system.


  1. If you need to use Java Hook please copy java folder to your project.

  2. Direct use of binary,You just copy the files under built/Android to src/main/jniLibs in your project.

  3. If you need to compile the source code, specify CMakeLists.txt in build.gradle:

externalNativeBuild {
  cmake {
      path "your/whale/path/CMakeLists.txt"


cd toolchain

cmake .. \
-DCMAKE_TOOLCHAIN_FILE=ios.toolchain.cmake \
-DIOS_ARCH=arm64 \

make -j4

Ohter platforms

cmake .
make -j4
