1.首先找到自己所需功能的开发文档,通过文档进行
2.例如,查看条码支付文档,创建自己的应用;https://docs.open.alipay.com/194/106039
3.配置此应用的公私钥,以及签约功能(个人是不可以签约的);
4.我们也可以通过沙箱环境进行测试(遇到错误,可以通过技术文档或者沙箱环境的错误集锦);
https://sandbox.alipaydev.com/user/accountDetails.htm?currentBar=1
5.编写代码:
(1)可以直接使用支付宝的SDK(下载sdk,最好也下载源码,方便查看);
//获得初始化的AlipayClient
AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do", APPID, RSA_PRIVATE, "json", "gbk", ALIPAY_PUBLIC_KEY, "RSA2");
//创建API对应的request类
AlipayTradePayRequest request = new AlipayTradePayRequest();
request.setBizContent("{" +
" \"out_trade_no\":\"" + getOutTradeNo() + "\"," +
" \"scene\":\"bar_code\"," +
" \"auth_code\":\"" + authCode + "\"," +
" \"subject\":\"Iphone6 16G\"," +
" \"store_id\":\"NJ_001\"," +
" \"timeout_express\":\"2m\"," +
" \"total_amount\":\"0.01\"" +
" }"); //设置业务参数
Runnable payRunnable = new Runnable() {
@Override
public void run() {
try {
Log.e("www", "request = " + request.getApiVersion());
AlipayTradePayResponse response = alipayClient.execute(request);
Log.e("www", "response = " + response.getBody());
} catch (AlipayApiException e) {
e.printStackTrace();
}
}
};
Thread payThread = new Thread(payRunnable);
payThread.start();
(2)使用http请求,可以通过查看之前的demo项目作为参考,
boolean rsa = true;
//构造支付订单参数列表
Map<String, String> params = OrderInfoUtil2_0.buildOrderParamMap(APPID, rsa,authCode);
//构造支付订单参数信息
String orderParam = OrderInfoUtil2_0.buildOrderParam(params);
Log.e("www", "orderParam = " + orderParam);
//对支付参数信息进行签名
String sign = OrderInfoUtil2_0.getSign(params, RSA_PRIVATE, rsa);
//订单信息
final String orderInfo = orderParam + "&" + sign;
Log.e("www", "orderInfo = " + orderInfo);
AlipayApi alipayApi = new AlipayApi(this, orderInfo);
alipayApi.getOkttpResponse();
alipayApi.setOnHttpResponseListener(new AlipayApi.OnHttpResponseListener() {
@Override
public void onHttpResponseListener(String response) {
parseGson(response);
}
});

添加权限

解决办法:

Google官方出的分包方案,采用MultiDex支持库
1,配置Modle的building.gradle,开启MultiDex
android {
defaultConfig {
multiDexEnabled true
}
}
dependencies{
compile'com.android.support:multidex:1.0.0'
}
2,配置应用
方法1:在AndroidManifest.xml的application中声明
android.support.multidex.MultiDexApplication;
package="com.example.android.multidex.myapplication">
...
android:name="android.support.multidex.MultiDexApplication">
...
方法2:让你自己的Application类继承MultiDexApplication
方法3:让你自己的Application类重写attachBaseContext
方法,
@Override
protected voidattachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
