Android微信登录是个坑（shareSDK）

第三方登录，只有微信是最麻烦的东西，之所以说麻烦是官方文档写的真的，网上的各种demo虽然能跑，但是却总有一些小问题注意不到。

首先，注册微信的开发者帐号，注意先生成Key文件，打包，然后再去获得微信需要的两个值。检查工具

微信包的位置，写法要严格

"com.jiuyuhulian.LiveRoom.wxapi.WXEntryActivity"
            android:theme="@android:style/Theme.Translucent.NoTitleBar"
            android:configChanges="keyboardHidden|orientation|screenSize"
            android:exported="true"
            android:screenOrientation="portrait"
        />

AndroidStudio的gradle虽然强大，但是也很难掌握，Asset文件夹，最好右键new->Folder->AssetFoleder去建立, 然后将ShareSDK的xml文件放进去。

代码就不贴了，可以去ShareSDK找最新的Demo, 切记不要拿Demo直接导入，有的版本很旧。
