cocos2d接安卓facebook插件（已测cocos-x 3.7 3.8版本）

1  控制台创建新工程：

　　a 控制台 进入cocos2d文件夹下面，如cocos2d-x-3.7.1，执行setup.py，未设置NDK SDK ANT 路径的设置路径，需要改路径的 explore 命令改路径，source 命令保存

　　b new 一个工程，我的是js工程，cocos new -p com.xxxxx.aiw -l js ~/workspace/test,一顿等待，在用户名下的workspace里出现了新的工程文件夹

2 没facebook的注册新账号，我注册时候要上传身份照片，不是美帝没身份证么，还查户口啊，果断借了个同事账号，账号下新建一个app，得到AppID，下面开启安卓开发选项，此时需要KeyHashs，具体看http://www.cnblogs.com/pengyingh/articles/4759575.html

3 具体参考 http://www.cocos.com/doc/article/index?type=cocos2d-x&url=/doc/cocos-docs-master/manual/framework/cocos2d-js/catalog/../../html5/facebook-sdk/facebook-sdk-on-android/zh.md

　　为增加代入感，复述一遍

　　a 在frameworks/runtime-src/proj.android/res/values/strings.xml添加app name和app id：

　　b 在frameworks/runtime-src/proj.android/AndroidManifest.xml添加以下代码片段：

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id" />

<activity android:name="com.facebook.LoginActivity" />
<provider android:authorities="com.facebook.app.NativeAppCallContentProvider1450063488603945"
          android:name="com.facebook.NativeAppCallContentProvider"
          android:exported="true"/>

　　c 在frameworks/runtime-src/proj.android/jni/Android.mk中添加Plugin-x链接库：

LOCAL_WHOLE_STATIC_LIBRARIES += jsb_pluginx_static
$(call import-module,cocos2d-x/plugin/jsbindings)

　　ps：改成

$(call import-module,plugin/jsbindings) 否则找不到路径
pps:如果还不行一定是添加顺序问题

LOCAL_WHOLE_STATIC_LIBRARIES += jsb_pluginx_static
LOCAL_EXPORT_CFLAGS := -DCOCOS2D_DEBUG= -DCOCOS2D_JAVASCRIPT

include $(BUILD_SHARED_LIBRARY)

$(call import-module, scripting/js-bindings/proj.android)
$(call import-module, plugin/jsbindings)

要这样，我会说谎？

为啥这样改？看下面。。。

/tools/cocos2d-console/plugins/project_compile/build_android.py

self.ndk_module_paths = cfg['ndk_module_path']

这里ndk_module_path就是build_cfg.json里面的参数

"ndk_module_path" :[
        "../../cocos2d-x",
        "../../cocos2d-x/cocos",
        "../../cocos2d-x/external"
    ],

def do_ndk_build(self, ndk_build_param, build_mode, compile_obj):
        cocos.Logging.info(MultiLanguage.get_string('COMPILE_INFO_NDK_MODE', build_mode))
        ndk_root = cocos.check_environment_variable('NDK_ROOT')

        toolchain_version = self.get_toolchain_version(ndk_root, compile_obj)

        if self.use_studio:
            ndk_work_dir = os.path.join(self.app_android_root, 'app')
        else:
            ndk_work_dir = self.app_android_root
        reload(sys)
        sys.setdefaultencoding('utf8')
        ndk_path = cocos.CMDRunner.convert_path_to_cmd(os.path.join(ndk_root, "ndk-build"))

        module_paths = []
        for cfg_path in self.ndk_module_paths:
            if cfg_path.find("${ENGINE_ROOT}") >= :
                cocos_root = cocos.check_environment_variable("COCOS_X_ROOT")
                module_paths.append(cfg_path.replace("${ENGINE_ROOT}", cocos_root))
            elif cfg_path.find("${COCOS_FRAMEWORKS}") >= :
                cocos_frameworks = cocos.check_environment_variable("COCOS_FRAMEWORKS")
                module_paths.append(cfg_path.replace("${COCOS_FRAMEWORKS}", cocos_frameworks))
            else:
                module_paths.append(os.path.join(self.app_android_root, cfg_path))
#打印一下

#hhahahah1:~AIW/frameworks/runtime-src/proj.android/../../cocos2d-x    安卓工程文件夹的爷爷文件夹下的cocos2d-x

#hhahahah1:~AIW/frameworks/runtime-src/proj.android/../../cocos2d-x/cocos   安卓工程文件夹的爷爷文件夹下的cocos2d-x下的cocos文件夹

#hhahahah1:~AIW/frameworks/runtime-src/proj.android/../../cocos2d-x/external  安卓工程文件夹的爷爷文件夹下的cocos2d-x下的external文件夹

#好吧你赢了 end

        # delete template static and dynamic files
        obj_local_dir = os.path.join(ndk_work_dir, "obj", "local")
        if os.path.isdir(obj_local_dir):
            for abi_dir in os.listdir(obj_local_dir):
                static_file_path = os.path.join(ndk_work_dir, "obj", "local", abi_dir)
                if os.path.isdir(static_file_path):
                    self.remove_c_libs(static_file_path)

        # windows should use ";" to seperate module paths
        if cocos.os_is_win32():
            ndk_module_path = ';'.join(module_paths)
        else:
            ndk_module_path = ':'.join(module_paths)

        ndk_module_path= 'NDK_MODULE_PATH=' + ndk_module_path

        if ndk_build_param is None:
            ndk_build_cmd = '%s -C %s %s' % (ndk_path, ndk_work_dir, ndk_module_path)
        else:
            ndk_build_cmd = '%s -C %s %s %s' % (ndk_path, ndk_work_dir, ' '.join(ndk_build_param), ndk_module_path)

        ndk_build_cmd = '%s NDK_TOOLCHAIN_VERSION=%s' % (ndk_build_cmd, toolchain_version)

        if build_mode == 'debug':
            ndk_build_cmd = '%s NDK_DEBUG=1' % ndk_build_cmd

        self._run_cmd(ndk_build_cmd)

结束语：ndk_module_path中是不包含 cocos2d-x这个文件的父文件路径的，所以

$(call import-module,cocos2d-x/plugin/jsbindings) 找路径不到就正常啦   >  <
改改改

　  d 在frameworks/runtime-src/proj.android/jni/hellojavascript/main.cpp文件中添加以下代码片段:

#include "PluginJniHelper.h"
void cocos_android_app_init (JNIEnv* env, jobject thiz) {
    LOGD("cocos_android_app_init");
    AppDelegate *pAppDelegate = new AppDelegate();
    JavaVM* vm;
    env->GetJavaVM(&vm);
    PluginJniHelper::setJavaVM(vm);
}

　　e 在frameworks/runtime-src/Classes/AppDelegate.cpp中添加如下代码片段。注意：请留意插入代码的位置：

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
#include "jsb_cocos2dx_pluginx_auto.hpp"
#include "jsb_pluginx_extension_registration.h"
#endif

bool AppDelegate::applicationDidFinishLaunching()
{
    ScriptingCore* sc = ScriptingCore::getInstance();

    ...

    // Add these lines before sc->start()
    #if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS || CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
        sc->addRegisterCallback(register_all_pluginx_protocols);
        sc->addRegisterCallback(register_pluginx_js_extensions);
    #endif

    sc->start();    

    ...

    return true;
}

　　f 在frameworks/runtime-src/proj.android/build-cg.json文件的copy_resources添加如下代码片段：

{
    "from": "../../js-bindings/cocos2d-x/plugin/jsbindings/script",
    "to": ""
},
{
    "from": "../../js-bindings/cocos2d-x/plugin/protocols/proj.android/src",
    "to": "../src"
},
{
    "from": "../../js-bindings/cocos2d-x/plugin/plugins/facebook/proj.android/src",
    "to": "../src"
},
{
    "from": "../../js-bindings/cocos2d-x/plugin/plugins/facebook/proj.android/sdk",
    "to": "../libs"
}

from是相对于工程的目录，例如在我的工程目录下，就是 ~/workspace/projects/AIW/frameworks/runtime-src/proj.android ，../是工程爸爸所在目录   ../../工程爷爷目录 如此理解发现这里路径就不对了

改为

{
    "from": "../../cocos2d-x/plugin/jsbindings/script",
    "to": ""
},
{
    "from": "../../cocos2d-x/plugin/protocols/proj.android/src",
    "to": "../src"
},
{
    "from": "../../cocos2d-x/plugin/plugins/facebook/proj.android/src",
    "to": "../src"
},
{
    "from": "../../cocos2d-x/plugin/plugins/facebook/proj.android/sdk",
    "to": "../libs"
}

注：to 是 assets文件夹下，../是assets文件夹所在的目录

具体参看： build_android.py

路径 ~/cocos2d-x-3.7.1（根据每个人版本不同）/tools/cocos2d-console/plugins/project_compile/build_android.p

if self.use_studio:
            assets_dir = os.path.join(self.app_android_root, "app", "assets")
            project_name = None
            setting_file = os.path.join(self.app_android_root, 'settings.gradle')
            if os.path.isfile(setting_file):
                # get project name from settings.gradle
                f = open(setting_file)
                lines = f.readlines()
                f.close()

                pattern = r"project\(':(.*)'\)\.projectDir[ \t]*=[ \t]*new[ \t]*File\(settingsDir, 'app'\)"
                for line in lines:
                    line_str = line.strip()
                    match = re.match(pattern, line_str)
                    if match:
                        project_name = match.group()
                        break

            if project_name is None:
                # use default project name
                project_name = 'app'
            gen_apk_folder = os.path.join(self.app_android_root, 'app/build/outputs/apk')
        else:
            assets_dir = os.path.join(self.app_android_root, "assets")
            project_name = self._xml_attr(self.app_android_root, 'build.xml', 'project', 'name')
            gen_apk_folder = os.path.join(self.app_android_root, 'bin')

 # copy resources
        for cfg in res_files:
            cocos.copy_files_with_config(cfg, app_android_root, assets_dir)

cocos.py

~/cocos2d-x-3.7.1/tools/cocos2d-console/bin/cocos.py

def copy_files_with_config(config, src_root, dst_root):
    src_dir = config["from"]
    dst_dir = config["to"]

    src_dir = os.path.join(src_root, src_dir)
    dst_dir = os.path.join(dst_root, dst_dir)

    include_rules = None
    if "include" in config:
        include_rules = config["include"]
        include_rules = convert_rules(include_rules)

    exclude_rules = None
    if "exclude" in config:
        exclude_rules = config["exclude"]
        exclude_rules = convert_rules(exclude_rules)

    copy_files_with_rules(
        src_dir, src_dir, dst_dir, include_rules, exclude_rules)

　　　　g 在frameworks/runtime-src/proj.android/project.properties中添加如下代码片段：

android.library.reference.=../../cocos2d-x/plugin/plugins/facebook/proj.android/DependProject

注：如果此处路径添加错误　　　可能会有错误

　h 在frameworks/runtime-src/proj.android/src/org/cocos2dx/javascript/AppActivity.java中添加如下代码片段：

public class AppActivity extends Cocos2dxActivity {

    //...

        super.onSaveInstanceState(outState);
        FacebookWrapper.onSaveInstanceState(outState);
    }

    //...
}

proj.android就是我们的工程 * 100 说一百遍，src里面就是调用的java文件，copyResource正确，里面会出现plugin文件夹

前面第三条c点得作用很重要

LOCAL_WHOLE_STATIC_LIBRARIES += jsb_pluginx_static
$(call import-module, plugin/jsbindings)

plugin/jsbindings 下有一个Android.mk

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := jsb_pluginx_static

LOCAL_MODULE_FILENAME := libcocos2dxjsbpluginx

LOCAL_SRC_FILES := auto/jsb_cocos2dx_pluginx_auto.cpp \
                   manual/jsb_pluginx_basic_conversions.cpp \
                   manual/jsb_pluginx_extension_registration.cpp \
                   manual/jsb_pluginx_manual_callback.cpp \

                    $(LOCAL_PATH)/../protocols/include

LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/manual \

LOCAL_WHOLE_STATIC_LIBRARIES += PluginProtocolStatic

include $(BUILD_STATIC_LIBRARY)

$(call import-module,external/spidermonkey/prebuilt/android)
$(call import-module,.)
$(call import-module,plugin/protocols/proj.android/jni)

LOCAL_C_INCLUDES := ...

manual auto 等等引用，此时main.cpp中的    #include "PluginJniHelper.h" 再也不会找不到所在地了

4 打包:在工程下

cocos run -p android -j 4

-j参数指定使用多少个线程执行编译，官方的说法是可以加快编译速度。（可选项）

接个facebook费半管血，毁在平时没怎么学习android，话说一个游戏开发工具，教程也n久不更新，接个插件要使用者做这么多工作，真的好么？免费不是借口，我还是学习去吧。。

注意：1. 打包前需要修改 proj.android 目录下的 build_native.py  文件

resources_dir = os.path.join(app_android_root, "../../cocos2d-x/cocos/scripting/js-bindings/script") #pengyingh

cocos_root = os.path.join(project_root, "..", "..", "cocos2d-x") #pengyingh

2.如果build报错
