I want to develop an application which does payment processing through authorize.net
But everytime I get unknown error.
First I fill all the textboxes and use these values on a button click event.
My code is:
txtAmount=Double.parseDouble(Amount.getText().toString());
txtFName = FName.getText().toString();
txtLName=LName.getText().toString();
txtAddress=Address.getText().toString();
txtCity=City.getText().toString();
txtState=State.getText().toString();
txtzipcode=zipcode.getText().toString();
txtEmail=Email.getText().toString();
txtCreditCard=CreditCard.getText().toString();
txtCVV2=CVV2.getText().toString();
drpMonth=selectedmonth;
drpYear=selectedyear;
date= drpMonth.concat(drpYear);
try {
URL post_url = new URL("https://test.authorize.net/gateway/transact.dll");
Hashtable post_values = new Hashtable();
// the API Login ID and Transaction Key must be replaced with valid values
post_values.put ("x_login", "8SX5gkJb46g");
post_values.put ("x_tran_key", "8Wx295Gr4hd9Y5kd");
post_values.put ("x_version", "3.1");
post_values.put ("x_delim_data", "TRUE");
post_values.put ("x_delim_char", "|");
post_values.put ("x_relay_response", "FALSE");
post_values.put ("x_type", "AUTH_CAPTURE");
post_values.put ("x_method", "CC");
post_values.put ("x_card_num", txtCreditCard);
post_values.put ("x_exp_date", date);
post_values.put ("x_amount", txtAmount);
post_values.put ("x_description", "Sample Transaction");
post_values.put ("x_first_name",txtFName);
post_values.put ("x_last_name",txtLName);
post_values.put ("x_address", txtAddress);
post_values.put ("x_city", txtCity);
post_values.put ("x_state",txtState);
post_values.put ("x_zip", txtzipcode);
post_values.put ("x_email", txtEmail);
// Additional fields can be added here as outlined in the AIM integration
// guide at: http://developer.authorize.net
// This section takes the input fields and converts them to the proper format
// for an http post. For example: "x_login=username&x_tran_key=a1B2c3D4"
StringBuffer post_string = new StringBuffer();
Enumeration keys = post_values.keys();
while( keys.hasMoreElements() ) {
String key = URLEncoder.encode(keys.nextElement().toString(),"UTF-8");
String value = URLEncoder.encode(post_values.get(key).toString(),"UTF-8");
post_string.append(key + "=" + value + "&");
}
// Open a URLConnection to the specified post url
URLConnection connection = post_url.openConnection();
connection.setDoOutput(true);
connection.setUseCaches(false);
// this line is not necessarily required but fixes a bug with some servers
connection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
// submit the post_string and close the connection
DataOutputStream requestObject = new DataOutputStream(connection.getOutputStream());
requestObject.write(post_string.toString().getBytes());
requestObject.flush();
requestObject.close();
// process and read the gateway response
BufferedReader rawResponse = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
String responseData = rawResponse.readLine();
rawResponse.close(); // no more data
// split the response into an array
String [] responses = responseData.split("|");
// The results are output to the screen in the form of an html numbered list.
for(Iterator iter=Arrays.asList(responses).iterator(); iter.hasNext();) {
result="\n"+ iter.next() +" ";
tv.setText(result);
//out.println("<LI>" + iter.next() + " </LI>");
}
setContentView(tv);
} catch(Exception e) {
tv.setText(e.getMessage());
setContentView(tv);
}
Can anyone help me?
through setContentView I am showing my splited result and I get only unknown error exception. No other description is shown. Is my method wrong or there is any other method to implement payment processing ?
Thanks for your code :) I got new idea form your code to implement authorize.net in android I have no idea what you faced error but when I tried to use post url for integration I faced one error and I have added "x_market_type" in my code and I got the result
post_values.put ("x_market_type", "2");
If you need any help than post comment. :)

Recommend you use the HTTPClient instead as shown in this example How do I make an http request using cookies on Android?
From what I can see in your code:
- This section will given an extra & at the end
while( keys.hasMoreElements() ) { String key = URLEncoder.encode(keys.nextElement().toString(),"UTF-8"); String value = URLEncoder.encode(post_values.get(key).toString(),"UTF-8"); post_string.append(key + "=" + value + "&");}
- You read only a single line of what has been returned by the server. Even though the content might be placed in one line, the HTTP headers will span several lines
String responseData = rawResponse.readLine();
- You use the default user-agent request header which may not be accepted by the server
If you want to try fixing your current code, I recommend you debug it or throw in some log statements (which you can view with for example the aLogCat application)
