In Eclipse ? Not Cocos Code IDE ? You will need some extra steps for eclipse, @joshua_astray could explain more details for you
Hello, @shadiho.
I just read your document, and all the steps you did are perfect. The only problem is in step 5.
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
sc->addRegisterCallback(register_all_pluginx_protocols);
sc->addRegisterCallback(register_pluginx_js_extensions);
#endif
these lines should be added before sc->start();. Sorry for lack of explaining in the document.

guys, I really appreciate your help, I fixed the issue and facebook login worked perfectly with me, I updated the step by step document and attach it again here, if you find this document useful, you can use it and published in any way.
The next step is integration with adMob, so I will try to do it alone and if I face any issue I will seek your help again 
(also I will prepare a document for the same)
facebook Integration Step by Step.zip (1004.5 KB)
We encourage you to post the document in a separated post directly, and you can post it in your blog or something if you want.
Google will help people find your solution.
