A pay library for Android, and which support Wechat pay and Ali pay. And developer can easily use Wechat pay in two lines of code. And developer can easily use Ali pay in three lines of code.
add these code in the file build.gradle as follow:
dependencies {
//add pay library
compile 'io.github.mayubao:pay_library:1.0.1'
}<dependency>
<groupId>io.github.mayubao</groupId>
<artifactId>pay_library</artifactId>
<version>1.0.1</version>
<type>pom</type>
</dependency>//1.create request for wechat payWechatPayReqwechatPayReq = newWechatPayReq.Builder()
.with(this) //activity instance
.setAppId(appid) //wechat pay AppID
.setPartnerId(partnerid)//wechat pay partner id
.setPrepayId(prepayid)//pre pay id// .setPackageValue(wechatPayReq.get)//"Sign=WXPay"
.setNonceStr(noncestr)
.setTimeStamp(timestamp)//time stamp
.setSign(sign)//sign
.create();
//2. send the request with wechat payPayAPI.getInstance().sendPayRequest(wechatPayReq);
//set the callback for wechat pay//wechatPayReq.setOnWechatPayListener(new OnWechatPayListener);Notes：WechatPayReq have no method to set the money, because the money info is include in the parameter 'prepayid'.
First way(Not Recommend, and its partner rsa private key export in the client , it is very dangerous!)
//step 1 create config for ali payAliPayAPI.Configconfig = newAliPayAPI.Config.Builder()
.setRsaPrivate(rsa_private) // rsa private key from partner (pkcs8 format)
.setRsaPublic(rsa_public)//ali rsa public key
.setPartner(partner) //set partner
.setSeller(seller) //set partner seller accout
.create();
//step 2 create reqeust for aliAliPayReqaliPayReq = newAliPayReq.Builder()
.with(activity)//Activity instance
.apply(config)// the above custome config
.setOutTradeNo(outTradeNo)//set unique trade no
.setPrice(price)//set price
.setSubject(orderSubject)//set order subject
.setBody(orderBody)//set order detail
.setCallbackUrl(callbackUrl)//set callback for pay reqest
.create()//
.setOnAliPayListener(null);////step 3 send the request for ali payPayAPI.getInstance().sendPayRequest(aliPayReq);
// set the ali pay callback//aliPayReq.setOnAliPayListener(new OnAliPayListener);//step 1 create raw ali pay order infoStringrawAliOrderInfo = newAliPayReq2.AliOrderInfo()
.setPartner(partner) //set partner
.setSeller(seller) //set partner seller accout
.setOutTradeNo(outTradeNo) //set unique trade no
.setSubject(orderSubject) //set order subject
.setBody(orderBody) //set order detail
.setPrice(price) //set price
.setCallbackUrl(callbackUrl) //set callback for pay reqest
.createOrderInfo(); //create ali pay order info//step 2 get the signed ali pay order infoStringsignAliOrderInfo = getSignAliOrderInfoFromServer(rawAliOrderInfo);
//step 3 step 3 send the request for ali payAliPayReq2aliPayReq = newAliPayReq2.Builder()
.with(activity)//Activity instance
.setSignedAliPayOrderInfo(signAliOrderInfo)
.setRawAliPayOrderInfo(rawAliOrderInfo)//set the ali pay order info
.setSignedAliPayOrderInfo(signAliOrderInfo) //set the signed ali pay order info
.create()//
.setOnAliPayListener(null);//PayAPI.getInstance().sendPayRequest(aliPayReq);
//set the ali pay callback//aliPayReq.setOnAliPayListener(new OnAliPayListener);How to do ：
1.new folder named 'wxapi' under your project root package
2.and create class WXPayEntryActivity under the wxapi
3.implements IWXAPIEventHandler interface
The sample as follow：
importandroid.app.Activity;
importandroid.app.AlertDialog;
importandroid.content.Intent;
importandroid.os.Bundle;
importandroid.util.Log;
importandroid.widget.Toast;
importcom.tencent.mm.sdk.constants.ConstantsAPI;
importcom.tencent.mm.sdk.modelbase.BaseReq;
importcom.tencent.mm.sdk.modelbase.BaseResp;
importcom.tencent.mm.sdk.openapi.IWXAPI;
importcom.tencent.mm.sdk.openapi.IWXAPIEventHandler;
importcom.tencent.mm.sdk.openapi.WXAPIFactory;
publicclassWXPayEntryActivityextendsActivityimplementsIWXAPIEventHandler{
privatestaticfinalStringTAG = "MicroMsg.SDKSample.WXPayEntryActivity";
privateIWXAPIapi;
//TODO need to replace your APP_IDprivateStringAPP_ID = "wx0xxxxxxxxx"; //need to replace your APP_ID@OverridepublicvoidonCreate(BundlesavedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.pay_result);api = WXAPIFactory.createWXAPI(this, APP_ID);
api.handleIntent(getIntent(), this);
}
@OverrideprotectedvoidonNewIntent(Intentintent) {
super.onNewIntent(intent);
setIntent(intent);
api.handleIntent(intent, this);
}
@OverridepublicvoidonReq(BaseReqreq) {
}
@OverridepublicvoidonResp(BaseRespresp) {
Log.d(TAG, "onPayFinish, errCode = " + resp.errCode);
if (resp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) {
// AlertDialog.Builder builder = new AlertDialog.Builder(this);// builder.setTitle(R.string.app_tip);// builder.setMessage(getString(R.string.pay_result_callback_msg, String.valueOf(resp.errCode)));// builder.show();//send the wechat pay broadcast receiver，and you should the define wechat pay broadcast receive Intentintent = newIntent();
intent.setAction(WeChatPayReceiver.ACTION_PAY_RESULT);
intent.putExtra("result", resp.errCode);
sendBroadcast(intent);
finish();
}
}
