Question

Not familiar with c++, can someone help me add cmd to the myStr array and pass it to the main() function, here is what I have so far:

JNIEXPORT void JNICALL Java_my_package_JNIActivity_callCmdLine(
    JNIEnv *env, jobject obj, jstring cmd)
{
    const char *nativeString = env->GetStringUTFChars(cmd, 0);
    env->ReleaseStringUTFChars(cmd, nativeString);

    char * myStr [] = {"v", nativeString};

    //int main(int argc, char *argv[])
    main(1, myStr); 
}

Well, don’t release it before you’re finished with it.

char * nativeString;

{    const char * _nativeString = env->GetStringUTFChars(cmd, 0);
     nativeString = strdup (_nativeString);
     env->ReleaseStringUTFChars(cmd, _nativeString);
}

char * myStr [] = {"v", nativeString};
main(1, myStr); 

free (nativeString);
