Recently , i want to use cocos2d-x to write a cross-platform app , ios android .
But i want know " Can this lib be used to publish app to app store ?" first .
Hopetly to receive your anwser .

I found a bug in NDKHelper::HandleMessage.

CCObject *dataToPass = NDKHelper::GetCCObjectFromJson(methodParams);
dataToPass->retain();

dataToPass maybe is null.

I am not able to figure out how to add jansson and NDKHelper in CMakeLists. Any help on this will be appreciated.

HelloWorld::~HelloWorld()
{
// Remove the associated selector group from the global space,
// Because we are destroying this instance
string str = "HelloWorldSelectors";
char char_str = (char)str.c_str();
NDKHelper::RemoveSelectorsInGroup(char_str);
}

Hello,

Please, have a look at a commit in my fork of cocos2d-x:
vedi/cocos2d-x@28c0405

I've integrated your library to cocos2d-x. But it's not original library. I did some changes here:

• changed first letter of all the methods from upper to lower case (it better fits name conventions of cocos2d-x),
• renamed NDKCallbackNode (because it's confusing with nodes of cocos2d-x),
• fixed typo recIEve->recEIve in all the method,
• maybe something else, but actually I do not remember.

If you happy with these changes I can try to do a pull request to the original cocos2d-x repository, or you can do that by yourself.

Looking forward to your feedback.

Best regards,
Fedor Shubin

Cocos2d-x 3.0 some class deprecated， such as CCObject to Object:

EasyNDK/NDKHelper/NDKHelper.cpp:16:95: 'CCNode' is deprecated

NDKHelper/NDKHelper.cpp:45:1: 'CCObject' is deprecated

'CCDictionary' is deprecated

maybe you can change sdk to fix Cocos2d-x 3.0

This doesn't affect the EasyNDK, but is really annoying.

When I run the test project y got multiple console outputs like this:

Nov 19 18:46:30 iPad-de-Gonzalo SampleNDK[1128] : CGBitmapContextCreate: unsupported parameter combination: 8 integer bits/component; 32 bits/pixel; 3-component color space; kCGImageAlphaPremultipliedLast; 186 bytes/row.

Tested with:
Mac OS X 10.9 Mavericks / Xcode 5.0.1
iPad Mini wifi / iOS 7.0.2

I fix this issue upgrading the cocos2d-x library to current 2.2

What kind of license will you use on EasyNDK?

android 4.2 run , it will crash

This is not noted in documentation. If addChild was not called on the node, its methods will not be called.

This is mainly as a precaution. If the tutorials and sample code are followed exactly, this will not be an issue.

Hi,

I liked your library and it was so easy integrating it in my game.
I have successfully integrated the same and implemented couple of 3rd party SDKs both in iOS and Android using EasyNDK which was so fast and easy.

Wanted to ask if you are looking in to add the support for WP8 for calling C# methods in the same fashion with help of XAML.

Thank you for sharing such a good work with us.

I'm trying to pass an integer to the native method but I'm not sure how to do that with SendMessageWithParams. I keep getting weird values on the native side when I convert the NSObject to NSInteger.

Hello,

I am using Xcode 6.1 and cocos2dx v2.2
I Changed C++ dialect to C++11 for some of my needs but i got 4 EasyNDK errors

PS: Its working perfect for C++ Dialect "Compiler Default"
Can you hint me what is going wrong here
Thanks

EVENT_COME_TO_FOREGROUND is spelled incorrectly in jni\hellocpp\main.cpp

   in void NDKHelper::HandleMessage(json_t *methodName, json_t* methodParams)

  CCObject *dataToPass = NDKHelper::GetCCObjectFromJson(methodParams);
  //dataToPass retain count 1

  if (dataToPass != NULL)
          dataToPass->retain();
  //dataToPass retain count 2

        CCFiniteTimeAction* action = CCSequence::create(CCCallFuncND::create(target, sel, (void*)dataToPass), NULL);

        target->runAction(action);//without retain and release


  if (dataToPass != NULL)
          dataToPass->autorelease();
        //dataToPass retain count 2 autorelease_count 1

And When i get data in me method

   void  method(CCNode *sender, void *data){
   }

data have retain count 2 autorelease_count 1
Need remove one retain

Hi, i found a bug. When creating CCDictionary from JSON object we use autorelease object. And when parameters pass to Native equriment we get empty dictionary. So i added retatin when create CCDIctionary and release in every to_be_call function.

CCObject* NDKHelper::GetCCObjectFromJson(json_t *obj)
{
if (obj == NULL)
return NULL;

if (json_is_object(obj))
{
    CCDictionary *dictionary = CCDictionary::create();
    dictionary->retain();

.....

Log displayed issue:
{"calling_method_name":"getCoins","calling_method_params":{"coins":"0","gems":"0"}}
Ndk proceed key coins
Ndk proceed key gems
Ndk get dictionary with 2 keys
getCoins call
params count 0 //so we have empty dictionary
NULL string
NULL string

Hello,

First of all, thank you for your work :) It helped me a lot.

I made a repo that makes EasyNDK work better with the changes introduced in the latest version of Cocos2d-x. The code can be found here: https://github.com/alfonsocejudo/EasyNDK-for-cocos2dx3

Hello,
Hoping you are well.
I am not sure whether its an issue or not, but when removing selectors from group Xcode 4.5 throughs a warning of
Conversion of String Literal to Char * is Depreciated.

Rest Works like Magic
Thank You
