1APP_ABI := x86
2APP_STL := c++_shared
APP_STL := c++_shared is to fix the following errors:
ld: error: undefined symbol: std::__ndk1::cout
To compile:
cd code/android_mk/hello
ndk-build
It will generate two directories in hello: libs and obj..
adb push libs/x86/foo /data/local
adb push libs/x86/libc++_shared.so /data/local
adb shell
cd /data/local
export LD_LIBRARY_PATH=.
./foo
