Get started with Android SDK

Latest release: Version 1.34.0 (Changelog)

Requirements

  • AndroidX
  • API level 21 (Android 5.0) and above (distribution stats)
  • Kotlin 1.7.10 or higher

Resources

Installation

  1. Add the Sumsub maven repository to the repositories section in your build.gradle file.
repositories {
  maven { url "https://maven.sumsub.com/repository/maven-public/" }
}
  1. Add the following dependencies to your build.gradle file.
dependencies {
    // SumSub core
    implementation "com.sumsub.sns:idensic-mobile-sdk:$latestVersion"
    // Video Identification module
    implementation "com.sumsub.sns:idensic-mobile-sdk-videoident:$latestVersion"
  	// eID module
    implementation "com.sumsub.sns:idensic-mobile-sdk-eid:$latestVersion"
}

Initialization

🚧

Attention

Make sure you have configured your verification level and access token before initializing the SDK.

The following are initialization examples.


// use the 'accessToken' that you generated on your backend
val accessToken = "..."

val tokenExpirationHandler = object : TokenExpirationHandler {
    override fun onTokenExpired(): String? {
        // Access token expired
        // get a new one and pass it to the callback to re-initiate the SDK
        val newToken = "..." // get a new token from your backend
        return newToken
    }
}

val snsSdk = SNSMobileSDK.Builder(this)
    .withAccessToken(accessToken, onTokenExpiration = tokenExpirationHandler)
    .withLocale(Locale("en"))
    .build()

snsSdk.launch()


// use the 'accessToken' that you generated on your backend
String accessToken = "...";

TokenExpirationHandler tokenUpdater = () -> {
        // Access token expired
        // get a new one and pass it to the callback to re-initiate the SDK
        String newAccessToken = "..."; // get a new token from your backend
        return newAccessToken;
    };

SNSMobileSDK.SDK snsSdk = new SNSMobileSDK.Builder(requireActivity())
        .withAccessToken(accessToken, tokenUpdater)
        .withLocale(new Locale("en"))
        .build();

Dismissal

By default, once the applicant is approved, the SDK will be dismissed in 3 seconds automatically. You can adjust this time interval or switch the automatic dismissal off by setting the value of zero.

snsSdk.withAutoCloseOnApprove(0)

Also, in case you need to close the SDK programmatically.

snsSdk.dismiss()

Configuration

Applicant Data

If it is required, you can provide an email and/or a phone number that will be initially assigned to the applicant.

val snsSdk = SNSMobileSDK.Builder(this)
    ...
    .withConf(SNSInitConfig(email = "...", phone = "..."))
    .build()

snsSdk.launch()


SNSMobileSDK.SDK snsSdk = new SNSMobileSDK.Builder(requireActivity())
        ...
        .withConf(new SNSInitConfig("...", "...", null))
        .build();

Preferred Documents

For IDENTITY* steps, it is possible to specify the preferred country and document type to be selected automatically, thereby bypassing the DocType Selector screen.

Note that the provided parameters will be applied only if the corresponding combination of country and idDocType is allowed at the step according to the level configuration.

val snsSdk = SNSMobileSDK.Builder(this)
    ...
    .withPreferredDocumentDefinitions(mapOf(
        "IDENTITY" to SNSDocumentDefinition(idDocType = "DRIVERS", country = "USA")
    ))
    .build()

SNSMobileSDK.SDK snsSdk = new SNSMobileSDK.Builder(requireActivity())
        ...
        .withPreferredDocumentDefinitions(Map.of(
            "IDENTITY", new SNSDocumentDefinition("DRIVERS", "USA")
        ))
        .build();

Video identification

The VideoIdent is an optional module that is required only if you are going to use the Video identification during the verification flow.

To enable the module, add the following dependency to your build.gradle file.

dependencies {
    // Video Identification module
    implementation "com.sumsub.sns:idensic-mobile-sdk-videoident:$latestVersion"
}

eID

The eID is an optional module that is required only if you are going to use the eID during the verification flow.

To enable the module, add the following dependency to your build.gradle file.

dependencies {
    // eID module
    implementation "com.sumsub.sns:idensic-mobile-sdk-eid:$latestVersion"
}

NFC

Starting from MDSK 1.34.0, the NFC is an optional module that is required only if you are going to use the NFC during the verification flow.

To enable the module, add the following dependency to your build.gradle file.

dependencies {
    // NFC module
    implementation "com.sumsub.sns:idensic-mobile-sdk-nfc:$latestVersion"
}

Action Flow

In order to run the SDK in applicant action mode, you need to create an applicant flow of Applicant actions type in the dashboard and specify its name as the flowName initialization parameter.

Also, make an access token not only with the userId parameter, but with the externalActionId one as well.

Aside from the notes above, you manage the SDK the same way that you do with regular flows, the only difference is in how you get the action results.

File selection in gallery

You can specify the type of file requested from the gallery by overriding the resource string.

<string name="sns_gallery_type">*/*</string>

Users can preview PDF files on Android devices running 5.0 Lollipop and higher.

Low-light performance for our liveness detection

The SDK can operate using screen light in low-light conditions. The application must have additional permissions to change screen brightness. Accordingly, you can request that the applicant opens settings and adds the application to their device’s trusted list.


val intent = Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
startActivity(intent)

Obfuscation

The Sumsub MobileSDK contains necessary proguard rules. You don't need to add it manually.

Make sure you have disabled R8 full mode; in the gradle.properties, add the following line:

android.enableR8.fullMode=false

Reduce SDK size

You can reduce the size of your application's release build by removing TensorFlow library binaries, which will save about 7 MB, depending on the supported architectures.

Note that removing these libraries may affect some features of the Sumsub SDK:

  • Lower face detection accuracy in some cases.
  • The client-side photo quality detector will be disabled.
  • Automatic documents capture will be disabled.

To remove TensorFlow libraries from the resulting APK (or AAB), add the following code to the application's build.gradle file:

android {

    // excludes heavy TF *.so files from the apk.
    packagingOptions {
        exclude 'lib/**/libtensorflowlite_jni.so'
    }
