Implementation example

public class ExampleActivity extends Activity implements OnProcessCallback {
    private String filepath_front, filepath_back;
   
    //This variables are here just to provide some feedback on the expected structure and are not valid for the actual procedure
    private String public_key = "-----BEGIN PUBLIC KEY------\n" + 
                                    "MAAd1o3lksadgakOINYU09KJHNSACD" + 
                                    "akOIN9813HJMAJSBC109KJHNSACsad" +
                                    "sadgakOINY13HJMAJSBC109NSAC234" +
                                    "-----END PUBLIC KEY------" +
                                    
    private String liveness_token = "jkhfdaKJHF897123NGJHKJHS";

    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_example);

        //Object initialisation
        LivenessCustomisation customisation = new LivenessCustomisation();

        
        //Change company logo
        customisation.setAppLogo(R.drawable.logo)
            
        //Only required in some cases
        //customisation.setViewId(R.id.liveness_surface); 
        
        //A liveness token and public key are mandatory for the engine to properly work
        customisation.setLivenessToken(liveness_token);
        customisation.setPublicKey(public_key);
        
        //Required only for custom service deployments
        customisation.setAppId(getApplicationContext().getPackageName());
        customisation.setExpiryDate("Insert expiry date here");
        customisation.setLicenseKey("Insert license key here");
