每个U3D程序都要面临着接入第三方SDK的问题，之前接入的原生微信登录那套，这两天公司因为某种原因放弃了，准备接入Share SDK 的登录 和分享。

关于如何去Share官网注册，和去对应平台获取生产对应的秘钥。可以先阅读下这篇文章Unity 之MOB >ShareSDK流程详解 - 简书。(里面已经详细介绍了接入前的准备工作流程)

我写这篇文章是怕我以后一忙，自己忘记，毕竟这块技术含量很低，就是注意下配置的几个地方，如果是高手请忽略此文章。 不啰嗦，进入正题。

首先说下去官网下载画unity的继承 SDK,这里MOB 做的就是傻瓜式接入，这里贴上下载地址 免费SDK下载_第>三方SDK接口_Mob移动开发者平台

下载后的文件夹里找到ShareSDk.unitypackage,这个资源包含了所需要的安卓资源和ios资源，这样小白也就可以不用去关心资源摆放的问题。只需要关心接下来的几个配置的步骤，之后的版本虽有变化，但差别不大。

首先,在Scene中新建一个空物体，并挂上SDK提供的 ShareSDK脚本，填入ShareSDk 的App Key 和App Secret。打开折叠的Dev info修改里面，所需要的平台秘钥，最后挂上ShareSDKManager,这个是要我自己写的。

接着，是修改 AndrondManifest 配置表，将package=后面的包名换成自己项目的

最下面填入shareSDK的秘钥,这个配置表就修改好了

再来是导出对应包名的jar包，这个可以联系客服获取，然后客服给我返回了一个工具 PackUnity放到ta导给我的jar包列表里，让我以后可以自己修改包名。导好的jar包放到../Android/ShareSDK/libs文件夹下

我摘取了demo脚本里需要的代码部分放到ShareSDKManager

贴上代ShareSDKManager代码码
