To install the Preventor Android SDK, add the following to your project’s
build.gradle
file:- 1.Use minSdkVersion 23 in your
build.gradle (Module:app)
- 2.Add implementation
'com.preventor:preventor_sdk:2.0.73-alpha'
to your dependencies. - 3.Add repository depencencies in your
build.gradle (Project Settings)
- 4.In your
build.gradle (Project: app)
. Make sure you have the same version or higher"org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.10"
plugin. - 5.In your
gradle.properties (Project Properties)
add this lineandroid.enableJetifier=true
A complete
build.gradle
file should look similar to the example below.android {
// 1. Ensure you have hat least minSdkVersion 23
compileSdkVersion 32
defaultConfig {
applicationId "com.preventor.example"
minSdkVersion 23
targetSdkVersion 32
versionCode 1
versionName "1.0.0"
}
}
dependencies {
...
// 2. Add line here
implementation 'com.preventor:preventor_sdk:2.0.10-alpha'
}
// 3.
repositories {
jcenter()
maven { url "https://jitpack.io" }
maven { url 'https://button.preventor.com/__android/v2'}
}
You have successfully installed the Preventor SDK!
Initialize the SDK. See the coding example below:
Kotlin
Java
package com.preventor.example
// 1. Add import of Preventor SDK
import com.preventor.pvtidentityverification.PreventorSDK
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
// 2. Set the context to parameters "activity" and "ViewModelStoreOwner"
val preventorSDK = PreventorSDK(this, this)
}
}
package com.preventor.example;
// 1. Add import of Preventor SDK
import com.preventor.pvtidentityverification.PreventorSDK;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 2. Set the context to parameters "activity" and "ViewModelStoreOwner"
PreventorSDK preventorSDK = new PreventorSDK(this,this);
}
}
You have successfully initialize the Preventor SDK!
To continue with the integration you need to set the prefill shown below. First you must obtain the config object by calling
getConfig()
method.kotlin
Java
package com.preventor.example
import com.preventor.pvtidentityverification.PreventorSDK
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val preventorSDK = PreventorSDK(this, this)
// 1. GET CONFIG OBJECT
val config = preventorSDK.getConfig()
}
}
package com.preventor.example;
import com.preventor.pvtidentityverification.PreventorSDK;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PreventorSDK preventorSDK = new PreventorSDK(this,this);
// 1. GET CONFIG OBJECT
Config config = preventorSDK.getConfig();
}
}
The flow type defines the biometric process so you must select a flow type.
Kotlin
Java
package com.preventor.example
import com.preventor.pvtidentityverification.PreventorSDK
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
preventorSDK = PreventorSDK(this, this)
val config = preventorSDK.getConfig()
// 1. SET THE FLOW TYPE
config.flowId = "YOUR_FLOW_ID"
}
}
package com.preventor.example;
import com.preventor.pvtidentityverification.PreventorSDK;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PreventorSDK preventorSDK = new PreventorSDK(this,this);
Config config = preventorSDK.getConfig();
// 1. SET THE FLOW TYPE
config.setFlowId("YOUR_FLOW_ID");
}
}
You must assign the flow type code. If it is blank, it will take the flow type by default.
You must set all credentials values to correctly consume our services.
Kotlin
Java
package com.preventor.example
import com.preventor.pvtidentityverification.PreventorSDK
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
preventorSDK = PreventorSDK(this, this)
val config = preventorSDK.getConfig()
config.flowId= "YOUR_FLOW_ID"
// 2. SET THE CREDENTIALS
config.credentials.apiKey = "YOUR_API_KEY"
config.credentials.clientSecret = "YOUR_CLIENT_SECRET"
config.credentials.tenant = "YOUR_TENANT"
config.credentials.banknu = "YOUR_BANKNU"
config.credentials.env = "YOUR_ENV"
}
}
package com.preventor.example;
import com.preventor.pvtidentityverification.PreventorSDK;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PreventorSDK preventorSDK = new PreventorSDK(this,this);
Config config = preventorSDK.getConfig();
config.setFlowId("YOUR_FLOW_ID");
// 2. SET THE CREDENTIALS
config.getCredentials().setApiKey("YOUR_API_KEY");
config.getCredentials().setClientSecret("YOUR_CLIENT_SECRET");
config.getCredentials().setTenant("YOUR_TENANT");
config.getCredentials().setBanknu("YOUR_BANKNU");
config.getCredentials().setEnv("YOUR_ENV");
}
}
Value | Description |
---|---|
YOUR_API_KEY | your provided apikey. |
YOUR_CLIENT_SECRET | your provided clientsecret. |
YOUR_TENANT | your provided tenant. |
YOUR_BANKNU | your provided banknu. |
YOUR_ENV | your provided env. |
The Cifcode is the unique customer profile code.
If the Cifcode is empty, a unique code is assigned.
Kotlin
Java
package com.preventor.example
import com.preventor.pvtidentityverification.PreventorSDK
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
preventorSDK = PreventorSDK(this, this)
val config = preventorSDK.getConfig()
config.flowId= "YOUR_FLOW_ID"
config.credentials.apiKey = "YOUR_API_KEY"
config.credentials.clientSecret = "YOUR_CLIENT_SECRET"
config.credentials.tenant = "YOUR_TENANT"
config.credentials.banknu = "YOUR_BANKNU"
config.credentials.env = "YOUR_ENV"
// 3. SET THE CIF CODE
config.currentUserInfo.cifCode = "YOUR_CIFCODE"
}
}
package com.preventor.example;
import com.preventor.pvtidentityverification.PreventorSDK;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PreventorSDK preventorSDK = new PreventorSDK(this,this);
Config config = preventorSDK.getConfig();
config.setFlowId("YOUR_FLOW_ID");
config.getCredentials().setApiKey("YOUR_API_KEY");
config.getCredentials().setClientSecret("YOUR_CLIENT_SECRET");
config.getCredentials().setTenant("YOUR_TENANT");
config.getCredentials().setBanknu("YOUR_BANKNU");
config.getCredentials().setEnv("YOUR_ENV");
// 3. SET THE CIF CODE
config.getCurrentUserInfo().setCifCode("YOUR_CIFCODE");
}
}
Define an app title that indicates the process to be performed.
Kotlin
Java
preventorSDK.setTitleAppBar("YOUR_TITLE_APP_BAR")
preventorSDK.setTitleAppBar("YOUR_TITLE_APP_BAR")
To start a new verification, you first need to create the preventor verification button.
<com.preventor.pvtidentityverification.widgets.PreventorButton
android:id="@+id/identityVerificationButton"
android:layout_width="161dp"
android:layout_height="wrap_content"
android:layout_centerInParent="true" />
To start a verification, prepare the following:
- 1.Add the reference to verification button.
- 2.Call
initialize()
method to start the preventorSDK. - 3.Call
validateApiKey()
method to start the verification.
Kotlin
Java
// 1. Add verification button reference.
val identityVerificationButton = findViewById<PreventorButton>(R.id.identityVerificationButton)
// 2. Call initialize() method.
preventorSDK.initialize()
// 3. Call validateApiKey() method.
identityVerificationButton.setOnClickListener {
preventorSDK.validateApiKey()
}
// 1. Add verification button reference.
PreventorButton identityVerificationButton = findViewById(R.id.identityVerificationButton);
// 2. Call initialize() method.
preventorSDK.initialize();
// 3. Call validateApiKey() method.
identityVerificationButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
preventorSDK.validateApiKey();
}
});
To start verification you can also use this call
validateApiKey()
anywhere in your code when all necessary resources have already been completed.To find out if a user has completed the verification process, canceled it or there was an error. To do this, you can implement the following delegate / callback methods:
Method | Description |
---|---|
onStart | This callback method is triggered once a user starts the verification flow. |
onSubmitted | Method that is being called once verification data is submitted to Preventor. |
onFinish | Method that is being called once a user clicks the "Finish" button. |
onError | This callback method fires when a user canceled the verification flow, the verification ended with an error, or the user performed an incorrect process. You can use this to find out the reason for the error. Error codes: CANCELLED_BY_USER BIOMETRIC_AUTHENTICATION_FAILED BAD_STEP_BY_USER MISSING_PARAMETERS TIME_OUT |
onNextStep | This callback indicates that it is possible to proceed to the next verification |
onComplete | This callback indicates that all necessary resources have already been completed |
Should look similar to the example below.
Kotlin
Java
preventorSDK.callback(object : PreventorSDKListener {
override fun onStart() {
println("MainActivity onStart");
}
override fun onFinish(ticked: Ticked) {
println("MainActivity onFinish");
}
override fun onError(error: String) {
println("MainActivity onError: $error");
}
override fun onSubmitted(ticked: Ticked) {
println("MainActivity onSubmitted");
}
override fun onNextStep() {
println("MainActivity onNextStep");
}
override fun onComplete() {
println("MainActivity onComplete");
}
})
preventorSDK.callback(new PreventorSDKListener() {
@Override
public void onStart() {
System.out.println("MainActivity onStart");
}
@Override
public void onFinish(Ticked ticked) {
System.out.println("MainActivity onFinish");
}
@Override
public void onError(@NonNull String error) {
System.out.println("MainActivity onError: " + error);
}
@Override
public void onSubmitted(Ticked ticked) {
System.out.println("MainActivity onSubmitted");
}
@Override
public void onNextStep(Ticked ticked) {
System.out.println("MainActivity onNextStep");
}
@Override
public void onComplete(Ticked ticked) {
System.out.println("MainActivity onComplete");
}
});
When the verification is finished it will return a ticked object in which you can see the results of the verification. Within them take as reference cifcode, ticketId, flowStatus, dispositionStatus.
Result | Value |
---|---|
cifcode | The cifcode is the unique customer profile code. |
ticketId | The ticketId is the unique code of the verification. |
flowStatus | Indicates the general status of the ticket. See the following codes: ACCEPTED, IN_PROGRESS, REJECTED, ABANDONED. |
dispositionStatus | Indicates the current disposition of the ticket. See the following codes: PASSED, NEED_REVIEW, RETRY, FAILED, PROCESSING, LOST_CONECCTION |
When the ticket ends in the following combinations, flowStatus and dispositionStatus respectively:
Status | Description |
---|---|
ACCEPTED - PASSED | Verification completed successfully. |
IN_PROGRESS - NEED_REVIEW | Verification is complete but there is information to review. |
IN_PROGRESS - RETRY | Verification did not complete and requires retry. |
IN_PROGRESS - PASSED | One step of verification has been completed and you can move on to the next. |
REJECTED - FAILED | Verification has been refused due to negative results. |
ABANDONED - LOST_CONECCTION | The verification has failed due to some unhandled error and the connection has been lost. |
ABANDONED - TIME_OUT | Verification failed due to user inactivity. |
