Initialization

The method for initializing the Wepin Android PIN Pad Library is as follows.

import com.wepin.android.pinlib.WepinPin

Before creating an instance of WepinPin, please pass the app’s Activity Context, the app ID, and the app key assigned after app registration to the WepinPinParams object as shown below.

val wepinPinParams =  WepinPinParams(
            context = this,
            appId = "your-wepin-app-id",
            appKey = "your-wepin-app-key"
        )

Please create a WepinPin instance by passing the previously created WepinPinParams.

val wepinPin = WepinPin(wepinPinParams)

After creating the WepinPin instance, call the initialize method to complete the initialization.

val res = wepinPin.initialize(attributes)

parameters

atrributes <WepinPinAttributes>

• defualtLanguage <String> The default language setting for the PIN pad screen is 'en'. Currently supported languages are 'ko', 'en', and 'ja'.

Return value

CompletableFuture <Boolean> Returns true if successful, and false if it fails.

Example

Java

public class MainActivity extends ComponentActivity {
    private WepinLogin wepinLogin;
    private WepinPin wepinPin;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_example_main);

        initView();
        // Initialize Wepin Login Library 
        // ...

        // Initialize Wepin PIN Pad Library 
        WepinPinParams wepinPinParams = new WepinPinParams(
            this,
            "your-wepin-app-id",
            "your-wepin-app-key"
        );
        wepinPin = new WepinPin(wepinPinParams);
        
        WepinPinAttributes attributes = new WepinPinAttributes("en");
        CompletableFuture<InfResponse> res = wepinPin.initialize(attributes);
        if (res != null) {
            res.whenComplete((infResponse, error) -> {
                if (error == null) {
                    System.out.println(infResponse);
                } else {
                    System.out.println(error);
                }
            });
        }
        // ...
    }
}

Kotlin

class MainActivity : ComponentActivity() {
    private lateinit var wepinLogin: WepinLogin
    private lateinit var wepinPin: WepinPin
    override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

        setContentView(R.layout.activity_example_main)
    
        initView()
        // Initialize Wepin Login Libary 
        // ...
        
        // Initialize Wepin PIN Pad Libary 
        val wepinPinParams =  WepinPinParams(
            context = this,
            appId = 'your-wepin-app-id',
            appKey = 'your-wepin-app-key'
        )
        wepinPin = WepinPin(wepinPinParams)       
        var attributes = WepinPinAttributes("en")
        val res = wepinPin.initialize(attributes)
        res?.whenComplete { infResponse, error ->
          if (error == null) {
            println(infResponse)
          } else {
            println(error) 
          }
      }        
    // ...
}

isInitialized

You can use the isInitialized method to check if the WepinPin instance has been successfully initialized.

The return values are as follows

• <Boolean> Returns true if initialization was successful and false if it failed.

Example

Java

if(wepinPin.isInitialized()){
    // Success to initialize WepinPin
}

Kotlin

if(wepinPin.isInitialized()){
    // Success to initialize WepinPin
}

changeLanguage

wepinPin.changeLanguage("ko")

Changes the language displayed on the PIN pad screen. Currently, only 'ko', 'en', and 'ja' are supported.

Parameters

• language <String>

Return value

• CompletableFuture <Boolean> Returns true if successful and false if it fails.

Example

Java

wepinPin.changeLanguage("ko").whenComplete((res, err) -> {
    if (err == null) {
        System.out.println(res);
    } else {
        System.out.println(err);
    }
});

Kotlin

wepinPin.changeLanguage("ko").whenComplete{ res, err ->
    if (err == null) {
      println(res)
    } else {
      println(err)
    }
}
