支付宝支付流程图解
支付宝支付和微信支付区别:
支付流程：商户服务器需要将订单信息通过统一下单api到微信服务器请求预支付交易单
异步通知处理：通知频率不一样，如果异步通知的商户服务器没有给微信服务端有效反馈，微信服务端会以一定频率重发通知
（通知频率为15/15/30/180/1800/1800/1800/1800/3600，单位：秒）
支付结果校验：提供主动查询订单支付信息接口
支付宝：
网络请求方式:get
数据格式：json
签名算法：RSA(最难**的加密方式.)
支付流程：无需请求预支付交易单
异步通知处理:通知频率不一样，（通知频率为2m,10m,10m,1h,2h,6h,15h）
支付结果校验：不提供主动查询订单支付信息接口
支付宝开放平台:https://openhome.alipay.com/platform/home.htm下载SDK,这些活就是公司做;https://doc.open.alipay.com/doc2/detail.htm?treeId=54&articleId=104509&docType=1
//这是个调起支付宝的Demo，做了服务端和客户端的功能。但是开发中客户端请求后台是不需要做太多东西的，客户端只需要请求拿到支付宝完整的订单信息。然后直接调起支付宝即可。其他消息都是服务器做的。
微信：
网络请求:Post
数据格式：xml
签名算法：MD5

添加权限
<uses-permission Android:name="android.permission.INTERNET"/>
<uses-permissionandroid:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permissionandroid:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permissionandroid:name="android.permission.READ_PHONE_STATE" />
<uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE" />
添加混淆规则:在proguard-project.txt里添加以下相关规则：
-libraryjarslibs/alipaySDK-20150602.jar
-keep class com.alipay.android.app.IAlixPay{*;}
-keep class com.alipay.android.app.IAlixPay$Stub{*;}
-keep class com.alipay.android.app.IRemoteServiceCallback{*;}
-keep class com.alipay.android.app.IRemoteServiceCallback$Stub{*;}
-keep class com.alipay.sdk.app.PayTask{ public *;}
-keep class com.alipay.sdk.app.AuthTask{ public *;}
