Unfortunately Soomla is the best out ATM.

Oh well, I will try to understand it. Seems that I have no choice :\

Thank you.

We are working hard to bring this to the community as fast as possible.

I am looking forward to it :p

As are we :D

I give up.

Have wasted the entire week studying soomla. Still could not work.

I am now looking for jniHelper usage...

Stay tuned to our social media for more updates

A small question here.

This is the implementation of JniHelper.cpp in cocos2d folder.

I stuck for two days but I just modified a single place and it could run iab successfully.

//JniHelper.cpp 

bool JniHelper::getStaticMethodInfo(JniMethodInfo &methodinfo,
                                        const char *className, 
                                        const char *methodName,
                                        const char *paramCode) {
        if ((nullptr == className) ||
            (nullptr == methodName) ||
            (nullptr == paramCode)) {
            return false;
        }

        JNIEnv *env = JniHelper::getEnv();
        if (!env) {
            LOGE("Failed to get JNIEnv");
            return false;
        }
            
        jclass classID = _getClassID(className);
        if (! classID) {
            LOGE("Failed to find class %s", className);
            env->ExceptionClear();
            return false;
        }
		
		jmethodID methodID = env->GetStaticMethodID(classID, methodName, paramCode);
		
        if (! methodID) {
            LOGE("Failed to find static method id of %s", methodName);
            env->ExceptionClear();
            return false;
        }
            
        methodinfo.classID = classID;
        methodinfo.env = env;
        methodinfo.methodID = methodID;
        return true;
    }

And I commented out the section.

if (! methodID) {
            LOGE("Failed to find static method id of %s", methodName);
            env->ExceptionClear();
            return false;
        }

Without returning false, I did access the iab system. But I do not know why.

Does it work now?

Yes, although I did not really buy anything with my real credit card, I could get the iab dialog now.

OK COOL
