Android学习——在线支付
在线支付
使用Ping++实现在线支付
Ping++是为移动应用量身打造的下一代支付系统，开发者不需要编写冗长的代码，应付复杂的入网申请流程，简单几步就可以是你的移动应用福ode支付功能，从而更专注于开发应用本身。
官网：http://pingxx.com
支付渠道：
- 微信支付、微信扫码支付、微信红包、微信企业付款
- 支付宝支付、支付宝扫码支付
- 银联手机支付
- 京东支付
- 百度钱包
- 易宝支付
- Apple Pay
开发文档：https://www.pingxx.com/docs/overview/index
SDK下载：https://www.pingxx.com/docs/downloads
注意：使用Ping++实现在线支付需要验证企业信息
导入 Ping++ SDK，支持在线导入和下载 SDK 导入两种方式
客户端配置在线导入方式
- 在项目中的 build.gradle 中添加 bintray 仓库地址
allprojects {
repositories {
// ...其他仓库地址...
jcenter()
// 添加下面的 bintray 仓库地址
maven {
url "https://dl.bintray.com/pingxx/maven"
}
}
}- 在 module 中 的 build.gradle 中设置
dependencies {
implementation 'com.pingxx:pingpp-android:2.2.2' // (Ping++ 标准版 SDK) 必须添加
implementation 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:+' // 使用微信支付时添加,具体版本参考微信官方文档
implementation 'com.pingxx:pingpp-android-alipay:2.2.0' // 使用支付宝时添加
implementation 'com.pingxx:pingpp-android-upacp:2.2.0' // 使用银联支付时添加
implementation 'com.pingxx:pingpp-qpay:2.1.19' // 使用QQ钱包时添加
implementation 'com.pingxx:pingpp-cmbwallet:2.1.19' // 使用招行一网通时添加
implementation 'com.pingxx:pingpp-ccbpay:2.1.19' // 使用建行支付时添加
implementation 'com.pingxx:pingpp-android-cmpay:2.2.2' // 使用和包支付时添加
