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
Java
1
allprojects {
2
repositories {
3
// Existing repositories, like google() and jcenter()
4
maven { url 'https://s3.eu-central-1.amazonaws.com/com.kvalifika.sdk' }
5
}
6
}
Copied!
1
allprojects {
2
repositories {
3
// Existing repositories, like google() and jcenter()
4
maven { url 'https://s3.eu-central-1.amazonaws.com/com.kvalifika.sdk' }
5
}
6
}
Copied!
Please use minSdkVersion 21 in your build.gradle (Module) file
To install Kvalifika Android SDK, add the following to build.gradle (Module) file:
Kotlin
Java
1
dependencies {
2
// Insert line below to include our client library as a dependency.
3
implementation 'com.kvalifika:sdk:0.7.0'
4
}
Copied!
1
dependencies {
2
// Insert line below to include our client library as a dependency.
3
implementation 'com.kvalifika:sdk:0.7.0'
4
}
Copied!

Initialize the SDK

import Kvalifika:
1
import com.kvalifika.sdk.KvalifikaSDK
2
import com.kvalifika.sdk.KvalifikaSDKLocale
3
import com.kvalifika.sdk.KvalifikaSDKCallback
4
import com.kvalifika.sdk.KvalifikaSDKError
Copied!
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
Java
1
class MainActivity : AppCompatActivity() {
2
private lateinit var sdk: KvalifikaSDK
3
private val appId: String = "YOUR APP ID"
4
​
5
override fun onCreate(savedInstanceState: Bundle?) {
6
super.onCreate(savedInstanceState)
7
setContentView(R.layout.activity_main)
8
​
9
sdk = KvalifikaSDK.Builder(this, appId)
10
.locale(KvalifikaSDKLocale.EN)
11
.build()
12
}
13
}
Copied!
1
public class MainActivity extends AppCompatActivity {
2
private KvalifikaSDK sdk;
3
​
4
@Override
5
protected void onCreate(Bundle savedInstanceState) {
6
super.onCreate(savedInstanceState);
7
​
8
String appId = "YOU APP ID";
9
setContentView(R.layout.activity_main);
10
​
11
sdk = new KvalifikaSDK.Builder(this, appId)
12
.locale(KvalifikaSDKLocale.EN)
13
.build();
14
}
15
}
Copied!

Start Verification

Call sdk.startSession() on button click event:
Kotlin
Java
1
class MainActivity : AppCompatActivity() {
2
private lateinit var sdk: KvalifikaSDK
3
private val appId: String = "YOUR APP ID"
4
​
5
override fun onCreate(savedInstanceState: Bundle?) {
6
super.onCreate(savedInstanceState)
7
setContentView(R.layout.activity_main)
8
​
9
sdk = KvalifikaSDK.Builder(this, appId)
10
.locale(KvalifikaSDKLocale.GE)
11
.build()
12
​
13
}
14
​
15
// Start verification on button click
16
fun onVerificationPress(view: View?) {
17
sdk.startSession()
18
}
19
}
Copied!
1
public class MainActivity extends AppCompatActivity {
2
private KvalifikaSDK sdk;
3
​
4
@Override
5
protected void onCreate(Bundle savedInstanceState) {
6
super.onCreate(savedInstanceState);
7
​
8
String appId = "YOU APP ID";
9
setContentView(R.layout.activity_main);
10
​
11
sdk = new KvalifikaSDK.Builder(this, appId)
12
.locale(KvalifikaSDKLocale.EN)
13
.build();
14
}
15
​
16
public void onVerificationPress(View view) {
17
sdk.startSession();
18
}
19
}
Copied!

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
Java
1
sdk.callback(object : KvalifikaSDKCallback {
2
override fun onInitialize() {
3
Log.d("MainActivity", "initialized")
4
}
5
​
6
override fun onStart(sessionId: String) {
7
Log.d("MainActivity", "started")
8
}
9
​
10
override fun onFinish(sessionId: String) {
11
// Fetch session data here from your server
12
}
13
​
14
override fun onError(error: KvalifikaSDKError, message: String?) {
15
if(error == KvalifikaSDKError.INVALID_APP_ID) {
16
Log.d("MainActivity", "Invalid App ID")
17
