Ali Pay

First way(Not Recommend, and its partner rsa private key export in the client , it is very dangerous!)

        //step 1 create config for ali pay
        AliPayAPI.Config config = new AliPayAPI.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 ali
        AliPayReq aliPayReq = new AliPayReq.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 pay
        PayAPI.getInstance().sendPayRequest(aliPayReq);

        // set the ali pay callback
        //aliPayReq.setOnAliPayListener(new OnAliPayListener);

Second way(Highly Recommend)

        //step 1 create raw ali pay order info
        String rawAliOrderInfo = new AliPayReq2.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 info
        String signAliOrderInfo = getSignAliOrderInfoFromServer(rawAliOrderInfo);

        //step 3 step 3 send the request for ali pay
        AliPayReq2 aliPayReq = new AliPayReq2.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);
