Guide for integrating Kvalifika SDK into a native Android project

Use Kvalifika SDK to easily integrate into a native Android project. Before integrating Kvalifika, it is recommended to follow the steps described in Integration Guide and Initial Setup.

Naming of the properties and functions might be slightly modified depending on the version.

Installation

Add the following to the project's main build.gradle file:

Kotlin

allprojects {
    repositories {
        // Existing repositories, like google() and jcenter()
        maven { url 'https://s3.eu-central-1.amazonaws.com/com.kvalifika.sdk' }
    }
}

Java

allprojects {
    repositories {
        // Existing repositories, like google() and jcenter()
        maven { url 'https://s3.eu-central-1.amazonaws.com/com.kvalifika.sdk' }
    }
}

Please use minSdkVersion 21 in your build.gradle (Module) file

To install Kvalifika Android SDK, add the following to build.gradle (Module) file:

Kotlin

dependencies {
  // Insert line below to include our client library as a dependency.
  implementation 'com.kvalifika:sdk:0.7.0'
}

Java

dependencies {
  // Insert line below to include our client library as a dependency.
  implementation 'com.kvalifika:sdk:0.7.0'
}

Initialize the SDK

import Kvalifika:

import com.kvalifika.sdk.KvalifikaSDK
import com.kvalifika.sdk.KvalifikaSDKLocale
import com.kvalifika.sdk.KvalifikaSDKCallback
import com.kvalifika.sdk.KvalifikaSDKError

After that, you need to initialize SDK with your appId and secretKey

appId is Application ID and secretKey is Application Secret Key, generated from Admin Panel. See Initial Setup for details.

Kotlin

class MainActivity : AppCompatActivity() {
	 private lateinit var sdk: KvalifikaSDK
 	 private val appId: String = "YOUR APP ID"

	 override fun onCreate(savedInstanceState: Bundle?) {
			super.onCreate(savedInstanceState)
			setContentView(R.layout.activity_main)

			sdk = KvalifikaSDK.Builder(this, appId)
					.locale(KvalifikaSDKLocale.EN)
					.build()
	 }
}

Java

public class MainActivity extends AppCompatActivity {
	private KvalifikaSDK sdk;

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

		String appId = "YOU APP ID";
		setContentView(R.layout.activity_main);

		sdk = new KvalifikaSDK.Builder(this, appId)
			.locale(KvalifikaSDKLocale.EN)
			.build();
	 }
}

Start Verification

Call sdk.startSession() on button click event:

Kotlin

class MainActivity : AppCompatActivity() {
	 private lateinit var sdk: KvalifikaSDK
 	 private val appId: String = "YOUR APP ID"

	 override fun onCreate(savedInstanceState: Bundle?) {
			super.onCreate(savedInstanceState)
			setContentView(R.layout.activity_main)

			sdk = KvalifikaSDK.Builder(this, appId)
					.locale(KvalifikaSDKLocale.GE)
					.build()

	 }

	 // Start verification on button click
	 fun onVerificationPress(view: View?) {
			sdk.startSession()
	 }
}

Java

public class MainActivity extends AppCompatActivity {
	private KvalifikaSDK sdk;

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

		String appId = "YOU APP ID";
		setContentView(R.layout.activity_main);

		sdk = new KvalifikaSDK.Builder(this, appId)
			.locale(KvalifikaSDKLocale.EN)
			.build();
	 }

	 public void onVerificationPress(View view) {
		sdk.startSession();
	 }
}

Handling Verifications

It's useful to know that whether a user has completed the verification flow or canceled it. For this, you can implement the callback methods.

Callback Methods

Method	Description
onInitialize	This callback method is triggered when SDK is initialized.
onStart	This callback method is triggered when the user starts verification.
onFinish	This callback method is triggered when the user completes verification. Get session data here.
onError	This callback method is triggered on error (see Error Codes for more information)

Kotlin

sdk.callback(object : KvalifikaSDKCallback {
    override fun onInitialize() {
        Log.d("MainActivity", "initialized")
    }

    override fun onStart(sessionId: String) {
        Log.d("MainActivity", "started")
    }

    override fun onFinish(sessionId: String) {
		// Fetch session data here from your server
    }

    override fun onError(error: KvalifikaSDKError, message: String?) {
        if(error == KvalifikaSDKError.INVALID_APP_ID) {
    		Log.d("MainActivity", "Invalid App ID")
    	}

        if (error == KvalifikaSDKError.USER_CANCELLED) {
            Toast.makeText(applicationContext, "User cancelled", Toast.LENGTH_LONG).show()
        }

        if (error == KvalifikaSDKError.TIMEOUT) {
            Toast.makeText(applicationContext, "Timeout", Toast.LENGTH_LONG).show()
        }

        if (error == KvalifikaSDKError.SESSION_UNSUCCESSFUL) {
            Toast.makeText(applicationContext, "Session failed", Toast.LENGTH_LONG).show()
        }

        if (error == KvalifikaSDKError.ID_UNSUCCESSFUL) {

        }

        if (error == KvalifikaSDKError.REVERSE_PORTRAIT_NOT_ALLOWED) {
            Toast.makeText(applicationContext, "Reverse portrait is not allowed", Toast.LENGTH_LONG).show()
        }

        if (error == KvalifikaSDKError.FACE_IMAGES_UPLOAD_FAILED) {
            Toast.makeText(applicationContext, "Could not upload face images", Toast.LENGTH_LONG).show()
        }

        if (error == KvalifikaSDKError.DOCUMENT_IMAGES_UPLOAD_FAILED) {
            Toast.makeText(applicationContext, "Could not upload Id card or passport images", Toast.LENGTH_LONG).show()
        }
        
        if (error == KvalifikaSDKError.NO_MORE_ATTEMPTS) {
            Toast.makeText(applicationContext, "You have reached maximum attempts", Toast.LENGTH_LONG).show()
        }

        if (error == KvalifikaSDKError.UNKNOWN_INTERNAL_ERROR) {
            Toast.makeText(applicationContext, "Unknown error happened", Toast.LENGTH_LONG).show()
        }
    }
})

UI Customizations

Appearance

It is possible to customize the logo and icons and provide drawable resources.

Kotlin

sdk = KvalifikaSDK.Builder(this, appId, secretKey)
	.locale(KvalifikaSDKLocale.EN)
	.logo(R.drawable.logo)
	.documentIcon(R.drawable.document_icon)
	.activeFlashIcon(R.drawable.flash_on)
	.inactiveFlashIcon(R.drawable_flash_off)
	.cancelIcon(R.drawable.cancel_icon)
	.build()

Java

sdk = KvalifikaSDK.Builder(this, appId, secretKey)
	.locale(KvalifikaSDKLocale.EN)
	.logo(R.drawable.logo)
	.documentIcon(R.drawable.document_icon)
	.activeFlashIcon(R.drawable.flash_on)
	.inactiveFlashIcon(R.drawable_flash_off)
	.cancelIcon(R.drawable.cancel_icon)
	.build()

Language

It is possible to set locale when initializing SDK. Supported locales are:

Code	Language
EN	English
GE	Georgian
RU	Russian
SP	Spanish

Kotlin

sdk = KvalifikaSDK.Builder(this, appId, secretKey)
        .locale(KvalifikaSDKLocale.EN)
        .build()

Java

KvalifikaSDK sdk = new KvalifikaSDK.Builder(this, appId, secretKey)
        .locale(KvalifikaSDKLocale.EN)
        .build();

Development Mode

Without specifying mode SDK uses https://api.kvalifika.com

With development mode ON SDK uses https://apistaging.kvalifika.com

Kotlin

sdk = KvalifikaSDK.Builder(this, appId)
        .development(true)
        .build()

Java

KvalifikaSDK sdk = new KvalifikaSDK.Builder(this, appId)
        .development(true)
        .build();

ProGuard

If you are using ProGuard in the release build, add the following options:

-keep class com.facetec.sdk.** { *; }
