hello .
when i build proxybinder.cpp to libmyso.so i have got an error :
android_runtime/AndroidRuntime.h: No such file or directory

then i install NDK patch https://github.com/boyliang/ndk-patch

i copy the ndk-patch to $NDK_PATH/platforms/android-8/arch-arm
and add APP_PLATFORM := android-8 in Application.mk

the compiler error disappear but has link error :

it likes the libs for ndk_patch has not loaded . how can fix it . ?

请教一下 我注入的时候都是不成功的 我把log打印出来 显示 Ptrace dlopen fail. undefined symbol: sendmmsg，这个是什么问题呢。
