Integration

The SDK includes a maven repository - http://paynet-qa.clubber.me/reader/maven/ For Miura Shuttle model: Use TEST on emulators for events.

Setup maven

Android Maven repository can be found here. Add the repository to pom.xml:

<repository>
  id>reader-repo</id>
  <name>reader repo</name>
  <url>http://paynet-qa.clubber.me/reader/maven</url>
</repository>`

Setup gradle

Android Gradle repository can be found here. Add the following to repositories section:

 repositories {
...
   maven { url "https://jitpack.io" }
   maven { url "http://paynet-qa.clubber.me/reader/maven" }
...
 }

Add the following to dependencies:

dependencies {
...
  def readerVersion = // check the latest version :ref:`here<https://github.com/payneteasy/reader-example/wiki/Changelog>`
  compile 'com.payneteasy.android.reader:api:' + readerVersion
  compile ('com.payneteasy.android.reader:lib:' + readerVersion)

  compile 'com.payneteasy.android.reader.readers:readers-common-bluetooth:' + readerVersion
  compile ('com.payneteasy.android.reader.readers:readers-miura:' + readerVersion) {
      exclude group:'junit', module:'junit'
  }
...
}

For additional details, please refer to the complete Gradle example available here.

For Bluetooth Readers (Android)

Add the following to AndroidManifest.xml:

<uses-permission android:name="android.permission.BLUETOOTH"/>
   <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

For USB terminals (Android)

Add new file res/xml/device_filter.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>

  <!-- 0x1234 / 0x0101  PAX / S80 -->
  <usb-device vendor-id="4660" product-id="257" class="255" subclass="0" protocol="0"/>

  <!-- 0x11CA / 0x0219  VeriFone Inc / Trident USB Device 1.1 / bInterfaceClass = 10 CDC Data -->
  <usb-device vendor-id="4554" product-id="537" class="10" subclass="0" protocol="0"/>

</resources>

Add any activity element to AndroidManifest.xml:

<intent-filter>
      <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
  </intent-filter>
  <meta-data  android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" android:resource="@xml/device_filter" />`

Add to the activity:

public class MainActivity extends Activity {

   private final UsbPermissionResolver usbPermissionResolver = new UsbPermissionResolver();

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       ...
       usbPermissionResolver.checkPermission(getIntent(), this);
   }

   @Override
   protected void onNewIntent(Intent intent) {
       super.onNewIntent(intent);
       usbPermissionResolver.checkPermission(intent, this);
   }

   @Override
   protected void onDestroy() {
       super.onDestroy();
       usbPermissionResolver.unregister(this);
   }

   ...

   }

Note

Please see this commit for more information.

For Miura (Java)

Please see the example app-2 how to run and assemble the application for Miura Readers to run on JVM.

app-3-webstart shows how to run the application from a browser via Java WebStart:

Sample Code

Implement the IReaderPresenter interface:

@Override
  public ProcessingContinuation onCard(BankCard bankCard) {

      setStatus("onCard: %s", bankCard);

      return ProcessingContinuation.Builder
              .startSaleOnline()
              .processingBaseUrl  ( Config.SERVER_BASE_URL)
              .merchantLogin      ( Config.MERCHANT_LOGIN )
              .merchantControlKey ( Config.MERCHANT_KEY   )
              .merchantEndPointId ( Config.END_POINT_ID   )
              .orderDescription   ( "test description"    )
              .orderInvoiceNumber ( "invoice-"+System.currentTimeMillis())
              .orderMerchantData  ( "custom merchant data for a internal use")
              .customerPhone      ( "+7 499 918-64-41"    )
              .customerEmail      ( "info@payneteasy.com" )
              .customerCountry    ( "RUS"                 )
              .listener(new IProcessingStageListener() {
                  @Override
                  public void onStageChanged(ProcessingStageEvent aEvent) {
                      setStatus("processing: %s", aEvent);
                  }
              })
              .build();

  }

  @Override
  public void onReaderSerialNumber(String aKsn) {
      setStatus("onReaderSerialNumber: %s", aKsn);
  }

  @Override
  public void cardReaderStateChanged(CardReaderEvent cardReaderEvent) {
      setStatus("cardReaderStateChanged: %s", cardReaderEvent);
  }

  @Override
  public void onCardError(CardError cardError) {
      setStatus("onCardError: %s", cardError);
  }

  @Override
  public void onReaderNotSupported(CardReaderProblem aProblem) {
      setStatus("onReaderNotSupported: %s", aProblem);
  }

  @Override
  public void onAudioData(short[] shorts, int i) {
      // for visualization
  }

  @Override
  public ConfigurationContinuation onConfiguration() {
      return new ConfigurationContinuation.Builder()
              .configDir              ( new File(activity.getFilesDir(), "miura-config"))
              .configurationBaseUrl   ( Config.SERVER_CONFIG_URL  )
              .merchantLogin          ( Config.MERCHANT_LOGIN     )
              .merchantControlKey     ( Config.MERCHANT_KEY       )
              .merchantEndPointId     ( Config.END_POINT_ID       )
              .build();
  }

Note

Fill the Config.MERCHANT_LOGIN, Config.MERCHANT_KEY, Config.END_POINT_ID with your own values.

Starts the Reader Manager:

CardReaderInfo cardReader = CardReaderInfo.TEST;
BigDecimal amount = new BigDecimal(1);
String currency = "RUB";

SimpleCardReaderPresenter presenter = new SimpleCardReaderPresenter(this, statusView);
cardReaderManager = CardReaderFactory.findManager(this, cardReader, presenter, amount, currency, null);`

Deal with cardReaderManager:

ICardReaderManager.startSaleSession() starts a sale session
ICardReaderManager.stopSession() stops a session and releases resources
