Source code introduction: Through the call of code, we can overcome the disadvantage of not having our own server. First, we can test whether the code can run smoothly. It is absolutely different from the WeChat payment demo.

Source code effect:

Source code snippet:

 private String genProductArgs() {
        StringBuffer xml = new StringBuffer(); 
  
 try {
            String nonceStr = genNonceStr(); 
  
  
 xml.append( "" );
            List<namevaluepair> packageParams = new LinkedList<namevaluepair>();
            packageParams.add( new BasicNameValuePair( "appid" , Constants.APP_ID));
            packageParams.add( new BasicNameValuePair( "body" , "weixin" ));
            packageParams.add( new BasicNameValuePair( "mch_id" , Constants.MCH_ID));
            packageParams.add( new BasicNameValuePair( "nonce_str" , nonceStr));
            packageParams.add( new BasicNameValuePair( "notify_url" , "http://121.40.35.3/test" ));
            packageParams.add( new BasicNameValuePair( "out_trade_no" ,genOutTradNo()));
            packageParams.add( new BasicNameValuePair( "spbill_create_ip" , "127.0.0.1" ));
            packageParams.add( new BasicNameValuePair( "total_fee" , "1" ));
            packageParams.add( new BasicNameValuePair( "trade_type" , "APP" )); 
  
  
            String sign = genPackageSign(packageParams);
            packageParams.add( new BasicNameValuePair( "sign" , sign)); 
  
  
           String xmlstring =toXml(packageParams); 
  
 return xmlstring; 
  
        } catch (Exception e) {
            Log.e(TAG, "genProductArgs fail, ex = " + e.getMessage());
 return   null ;
