NDK의 JNI 에서 std 라이브러리 사용하기

 

-1-

아래 사진과 같이 path 등록해준다.

${env_var:ANDROID_NDK} <- 부분은 매크로 부분이니 매크로가 설정 되지 않았으면 ndk 설치 경로를 적어주면된다.

위 사진에 보면 "Application.mk" 파일이 보이는데 이와 파일 내용을 아래와 같이 작성해준다.

또 Android.mk 파일은 기존 쓰던데로 설정해 주면된다.

 

-- Application.mk -------------------------------------------------------------- FILE

APP_PLATFORM := android-9

 

APP_OPTIM := release

APP_ABI := armeabi armeabi-v7a

APP_STL := stlport_static

 

#APP_OPTIM := debug

#APP_ABI := armeabi

I'm using eclipse to develop an android app that also uses the ndk. I vectors in my app and I've done the necessary stuff to get them by including

APP_STL := stlport_static

 

In my Application.mk

Everything is working fine it compiles and runs but Eclipse keeps giving me errors when I use the vectors

std::vector<int> blah

for example creates an error. If I delete the error and keep going it compiles and runs fine.

 

I've added ${NDKROOT}/sources/cxx-stl/gnu-libstdc++/include

 

In my project config under C++ General -> Paths and Symbols -> include

It resolves #include <vector> fine (before I added the path above I had an error for this) but I still get errors using the vectors.

How can I get eclipse to stop giving me errors for this?

EDIT:

example error: Symbol 'vector' could not be resolved

EDIT 2:

I tried to add

using namespace std;

and then using vector blah and that causes a different error:

Invalid template arguments

Yes, that's it. I've tried to add the same with the same result. However, if you add stl_port headers It will do the trick. Of course it is not necessary to change as it works only in eclipse indexes. It will be usefull until you are going to use something that exists in gnu-libstdc++ and doesn't exist stl-port.

I am suing eclipse indigo rc2.

I added following line in Android.mk

LOCAL_C_INCLUDES += ${NDKROOT}/sources/cxx-stl/stlport/stlport

and Added following line in Application.mk

APP_STL := stlport_static

then automatically my ndk stlport path added in

Properties -> C++ General -> Paths and Symbols -> include

good luck! ^^
