android 微信登录与分享

android微信登录与分享这两个功能是很常用的，尤其是现在微信用户日益剧增，qq虽然很经典但是感觉大多数用来办公 每个写android的小伙伴估计都会写到这个功能，我也是很久没有写android了，这相当于是在毕业之后工作上面第一次写安卓  
程序，不管会不会，就是写。总会有办法解决问题的。

一、若要想深究其原理请查看官方文档 [https://open.weixin.qq.com/cgi-bin/showdocument?action=dir\_list&t=resource/res\_list&verify=1&id=open1419317851&token=3b00b7ce045a5330c4ff3325aef6d4bd19687bc9&lang=zh\_CN][https_open.weixin.qq.com_cgi-bin_showdocument_action_dir_list_t_resource_res_list_verify_1_id_open1419317851_token_3b00b7ce045a5330c4ff3325aef6d4bd19687bc9_lang_zh_CN]

二、准备工作

1、目前移动应用上微信登录只提供原生的登录方式，需要用户安装微信客户端才能配合使用。
    
    2、对于Android应用，建议总是显示微信登录按钮，当用户手机没有安装微信客户端时，请引导用户下载安装微信客户端。
    
    3、对于iOS应用，考虑到iOS应用商店审核指南中的相关规定，建议开发者接入微信登录时，先检测用户手机是否已安装微信客户端（使用sdk中isWXAppInstalled函数 ），对未安装的用户隐藏微信登录按钮，只提供其他登录方式（比如手机号注册登录、游客登录等）。

三、授权流程说明

1. 第三方发起微信授权登录请求，微信用户允许授权第三方应用后，微信会拉起应用或重定向到第三方网站，并且带上授权临时票据code参数；
    
    2. 通过code参数加上AppID和AppSecret等，通过API换取access_token；
    
    3. 通过access_token进行接口调用，获取用户基本数据资源或帮助用户实现基本操作。

四、集成流程和代码，感觉看了上面和官网的的流程也没有什么感觉，下面直接开始走流程  
  
（1）微信开放平台上账号中心申请成为开发者  
![SouthEast][]  
（2）在管理中心，创建一个应用，官网填写一个域名，需要注意的就是应用签名，应用签名也不需要此时就填写，或者随便填写一个，后面再用android studio打包生成apk安装在桌面然后在用工具GenSignature获取，虽然在程序里面不用，但是在微信里面是对应用签名作了校验，如果不对会在微信登录时候回调返回-6,应用包名需要与程序里面的包名一样，也就是与清单文件第二行的包名package一致，应用下载地址可不填  
![SouthEast 1][]  
（3）android studio作为开发工具，代码目录结构如图所示,JavaScriptUtil类多画进去了。  
![SouthEast 2][]  
（4）build.gradle

// 微信sdk
        compile 'com.tencent.mm.opensdk:wechat-sdk-android-with-mta:+'
    //google Gson
       compile group: 'com.google.code.gson', name: 'gson', version: '2.8.0'

（5）AnfroidMainfest.xml

<activity android:name=".wxapi.WXEntryActivity"
                android:exported="true">
            </activity>

(6)WXEntryActivity类，在com.iwiteks. PalamarToutism包下面新建wxapi包并新建WXEntryActivity类，注意名字和包名必须是wxapi和WXEntryActivity。
