**For arm64-v8a architecture so**
1. modify the Application.mk to the target architecture (arm64-v8a)
2. modify the Android.mk to build the matched source file
3. build hijack tool and example, push them into your device just like above
4. install /instruments/example/arm64_test_apk/app-debug.apk or write your own test apk, if you write your own test apk, remember to modify the "my_init" function to hook your own function in the example
5. other steps and information just follow the original Tutorial
