/// 3 调起微信支付，(前提：微信已安装，且没有被应用回收，即正常人工可以使用)
/// 新建一个包wxapi,建一个类名为WXPayEntryActivity作为接受微信的支付结果(回调名必须是：
/// 你的包名+.wxapi.WXPayEntryActivity),添加如下代码到Mainfast里面就行了 exported = true
/// activity android:name=".wxapi.WXPayEntryActivity" android:exported="true" 实现onResp函数
/// 不过，最终结果以服务器的返回为准notify_url，App等待并轮询结果，接下来就是要为了做安全性设计，
/// 把一些重要的东西放到服务器生生成，这样是为防止客户端被反编译，建议GenPackageSign/genProductArgs方法在服务端生成
