============================
.程式裡的APP key 要使用開發者後台所提供的.
.要使用app_signatures.apk將包名編譯成md5並且填入開發者後台當中.
.或是直接cmd line跑出來，在自己轉小寫

登入功能需要開通
前提:
要得到回傳訊息(不管發動態或是登入)
一定要在自己於微信後台註冊的package(自己的專案)下面
新增一個package 叫"wxapi"
然後在此package下面新增
"WXEntryActivity.java"並實作IWXAPIEventHandler則就可在onResp拿到回傳
注意:
package名稱(wxapi )跟java檔名稱(WXEntryActivity )一要要這樣叫
androidmenifest:
===========
分享動態功能
WXEntryActivity => SendToWXActivity
發送文字
.將app註冊到APP
.自訂TextView(EditText )
.自訂dialog(MMAlert)
.初始化一个 WXTextObject 对象(將要分享的文字放進去)
.初始化WXMediaMessage(WXTextObject放進去 )
.构造一个 Req(SendMessageToWX.Req)
.调用api接口发送数据到微信(api .sendReq(req) )
.WXEntryActivity 的onResp會顯示成功與否
其他發送訊息如程式sample所演示.
圖文同時的話目前找到用WXWebpageObject代替

在onResp回傳 =>BaseResp resp
做轉型
SendAuth.Resp sendResp = (SendAuth.Resp) resp;
取token
sendResp.token
// 官方文件寫錯(他寫code)，但實際上是 token
STEP1:user token to get access_token and openid
https://api.weixin.qq.com/sns/oauth2/access_token?appid=wxbff6de7ebe6c9498&secret=a50b0b62ae77557b289c487308aa9faa&code=0112342663e805e50dd7fbe001075d0L&grant_type=authorization_code
STEP2: use refresh_token
=>第一次可跳過，又或者你只需要取得一次用戶資訊，那也可跳過此步驟
https://api.weixin.qq.com/sns/oauth2/refresh_token?appid=wxbff6de7ebe6c9498&grant_type=refresh_token&refresh_token=OezXcEiiBSKSxW0eoylIeILPYvLIWkzXq-H0gG9o7k8Dt9ilr91flHHcPwl78kdLCCcgvEVqvNaksf3wpgyqlaIvgSqQwbgV9LnBvgafjJpdJa7R-XExsaMWDy_o7LpKMPkIGvnQsHpKY2_LP5z12g
STEP3: use access_token and openid get user info
