Example of calling android method from native code

blah.c

void Log(std::string s){

    JNIEnv *env;
    g_JavaVM->GetEnv((void**)&env, JNI_VERSION_1_6);

    jstring jstr1 = env->NewStringUTF(s.c_str());

    jclass clazz = env->FindClass("diff/strazzere/secret/method");
   // Later part is dalvik notation for parameters and return value, string param and void return value here
    jmethodID mid = env->GetStaticMethodID(clazz, "methodname", "(Ljava/lang/String;)V");

    jobject obj = env->CallStaticObjectMethod(clazz, mid, jstr1);
}

//In some initialization function with Environment variable

env->GetJavaVM(&g_JavaVM);
