3. Initiate payment

3.1 WeChat Payment

JPay.getIntance(mContext).toPay(JPay.PayMode.WXPAY, payParameters, new JPay.JPayListener() {
            @Override
            public void onPaySuccess() {
                Toast.makeText(mContext, "Successful Payment", Toast.LENGTH_SHORT).show()
            }

            @Override
            public void onPayError(int error_code, String message) {
                Toast.makeText(mContext, "Payment Failed>"+error_code+" "+ message, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onPayCancel() {
                Toast.makeText(mContext, "Payment Cancelled", Toast.LENGTH_SHORT).show();
            }
        });

payParameters are in JSON string format as follows:

{
  "appId": "",
  "partnerId": "",
  "prepayId": "",
  "sign": "",
  "nonceStr" : "",
  "timeStamp": ""
}

perhaps

JPay.getIntance(mContext).toWxPay(appId, partnerId, prepayId, nonceStr, timeStamp, sign, new JPay.JPayListener() {
            @Override
            public void onPaySuccess() {
                Toast.makeText(mContext, "Successful Payment", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onPayError(int error_code, String message) {
                Toast.makeText(mContext, "Payment Failed>"+error_code+" "+ message, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onPayCancel() {
                Toast.makeText(mContext, "Payment Cancelled", Toast.LENGTH_SHORT).show();
            }
        });

3.2 Alipay Payment

JPay.getIntance(mContext).toPay(JPay.PayMode.ALIPAY, orderInfo, new JPay.JPayListener() {
            @Override
            public void onPaySuccess() {
                Toast.makeText(mContext, "Successful Payment", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onPayError(int error_code, String message) {
                Toast.makeText(mContext, "Payment Failed>"+error_code+" "+ message, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onPayCancel() {
                Toast.makeText(mContext, "Payment Cancelled", Toast.LENGTH_SHORT).show();
            }
        });

perhaps

Alipay.getInstance(mContext).startAliPay(orderInfo, new JPay.JPayListener() {
            @Override
            public void onPaySuccess() {

            }

            @Override
            public void onPayError(int error_code, String message) {

            }

            @Override
            public void onPayCancel() {

            }
        });

Modify the application Id of build.gradle in the application to the package name of the application
Modify the default signature key when testing

Copy the key into the project's root directory (app) and modify the buildTypes configuration as follows

 signingConfigs {
        release {
            storeFile file("wxkey")
            storePassword '123456'
