我正在尝试创建和Android应用程序，可以使用主卡api通过信用卡支付。我按照本教程 - ＆gt;＆gt; https://developer.mastercard.com/portal/pages/viewpage.action?pageId=14876685但是它说没有找到网址。
这是我使用的代码：
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
((Button) findViewById(R.id.submit)).setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Context context = getApplicationContext();
String endPoint = "https://api.mastercard.com/payments/v1/purchase?Format=XML";
EditText cardNumberInput = (EditText) findViewById(R.id.cardNumberInput);
EditText expirationMonthInput = (EditText) findViewById(R.id.expirationMonthInput);
EditText expirationYearInput = (EditText) findViewById(R.id.expirationYearInput);
EditText cvvInput = (EditText) findViewById(R.id.cvvInput);
EditText cardHolderNameInput = (EditText) findViewById(R.id.cardHolderNameInput);
EditText amountInput = (EditText) findViewById(R.id.amountInput);
final double amount = Float.valueOf(amountInput.getText().toString());
final String currency = "USD";
final String companyId = "ComID";
final String companyPassword = "ComPass";
final String messageId = "001";
final String settlementId = "011";
final String cardHolderName = cardHolderNameInput.getText().toString();
final String accountNumber = cardNumberInput.getText().toString();
final String expiryMonth = expirationMonthInput.getText().toString();
final String expiryYear = expirationYearInput.getText().toString();
final String securityCode = cvvInput.getText().toString();
try {
// Send data
URL url = new URL(endPoint);
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
conn.setDoInput(true);
OutputStreamWriter request = new OutputStreamWriter(conn.getOutputStream());
// Create the XML to post
request.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
request.append("<PurchaseRequest>");
request.append("<MerchantIdentity>");
request.append("<CompanyId>");
request.append(companyId);
request.append("</CompanyId>");
request.append("<CompanyPassword>");
request.append(companyPassword);
request.append("</CompanyPassword>");
request.append("</MerchantIdentity>");
request.append("<Reference>");
request.append("<MessageId>");
request.append(messageId);
request.append("</MessageId>");
request.append("<SettlementId>");
request.append(settlementId);
request.append("</SettlementId>");
request.append("</Reference>");
request.append("<Amount>");
request.append("<Currency>");
request.append(currency);
request.append("</Currency>");
request.append("<Value>");
request.append(Double.toString(amount));
request.append("</Value>");
request.append("</Amount>");
request.append("<FundingCard>");
request.append("<CardholderName>");
request.append(cardHolderName);
request.append("</CardholderName>");
request.append("<AccountNumber>");
request.append(accountNumber);
request.append("</AccountNumber>");
request.append("<ExpiryMonth>");
request.append(expiryMonth);
request.append("</ExpiryMonth>");
request.append("<ExpiryYear>");
request.append(expiryYear);
request.append("</ExpiryYear>");
request.append("<SecurityCode>");
request.append(securityCode);
request.append("</SecurityCode>");
request.append("</FundingCard>");
request.append("</PurchaseRequest>");
request.flush();
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse(conn.getInputStream());
Node transactionResponseNode = doc.getElementsByTagName("TransactionResponse").item(0);
// Test for approval.
String response = transactionResponseNode.getNodeValue().trim().toUpperCase();
Log.d("**********Response", ""+response);
if (response.equals("APPROVED") == true) {
request.close();
String text = "The payment processed successfully. PHP" + amountInput.getText().toString()
+ " was charged to the account.";
Toast toast = Toast.makeText(context, text, Toast.LENGTH_LONG);
toast.show();
} else if (response.equals("DECLINED")) {
String text = "The payment was declined.";
Toast toast = Toast.makeText(context, text, Toast.LENGTH_LONG);
toast.show();
} else if (response.equals("ERROR")) {
String text = "Error Processing Payment.";
Toast toast = Toast.makeText(context, text, Toast.LENGTH_LONG);
toast.show();
}
} catch (MalformedURLException e) {
String text = "Error";
Toast toast = Toast.makeText(context, ""+e, Toast.LENGTH_LONG);
toast.show();
} catch (IOException e) {
String text = "Error";
Toast toast = Toast.makeText(context, ""+e, Toast.LENGTH_LONG);
toast.show();
} catch (ParserConfigurationException e) {
String text = "Error";
Toast toast = Toast.makeText(context, ""+e, Toast.LENGTH_LONG);
toast.show();
} catch (SAXException e) {
String text = "Error";
Toast toast = Toast.makeText(context, ""+e, Toast.LENGTH_LONG);
toast.show();
}
}
});
}
}
任何想法都会对我有所帮助。感谢。
这就是log cat所说的：

- 在UI线程上执行 UI工作，在非UI线程上非UI工作总是更好，但是Android's Honeycomb版本为法律。
- 使用后台主题进行网络通话。
- 使用Thread进行网络调用，然后使用Handler将数据放在用户界面上，或者使用所谓的无痛线程< / strong>在Android中，AsyncTask。
