1. public class MainActivity extends AppCompatActivity {
      private ActivityResultLauncher<MRZScannerConfig> launcher;
      @Override
      protected void onCreate(@Nullable Bundle savedInstanceState) {
         // ...
         // Set up the license via the MRZScannerConfig
         MRZScannerConfig config = new MRZScannerConfig();
         config.setLicense("DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9");
         // Set up a launcher and register the result callback for MRZScannerActivity.
         launcher = registerForActivityResult(new MRZScannerActivity.ResultContract(), result -> {
            if (result.getResultStatus() == MRZScanResult.EnumResultStatus.RS_FINISHED && result.getData() != null) {
               // user code after a successful scan
            } else if (result.getResultStatus() == MRZScanResult.EnumResultStatus.RS_CANCELED) {
               // user code after a canceled scan
            }
            if (result.getErrorString() != null && !result.getErrorString().isEmpty()) {
               // user code after a failed scan
            }
         });
         // Config a button on the UI. Launch the MRZScannerActivity when button clicked.
         findViewById(R.id.btn_navigate).setOnClickListener(v -> launcher.launch(config));
      }
   }
   

2. class MainActivity : AppCompatActivity() {
      private lateinit var launcher: ActivityResultLauncher<MRZScannerConfig>
      override fun onCreate(savedInstanceState: Bundle?) {
         // Set up the license via the MRZScannerConfig
         val config = MRZScannerConfig().apply {
            license = "DLS2eyJvcmdhbml6YXRpb25JRCI6IjIwMDAwMSJ9";
         }
         // Set up a launcher and register the result callback for MRZScannerActivity.
         launcher = registerForActivityResult(MRZScannerActivity.ResultContract()) { result ->
            if (result.resultStatus == MRZScanResult.EnumResultStatus.RS_FINISHED && result.data != null) {
                   // user code after a successful scan
            } else if (result.resultStatus == MRZScanResult.EnumResultStatus.RS_CANCELED) {
                   // user code after a canceled scan
            }
            if (result.errorString != null && result.errorString.isNotEmpty()) {
                   // user code after a failed scan
            }
         }
         // Config a button on the UI. Launch the MRZScannerActivity when button clicked.
         findViewById<View>(R.id.btn_navigate).setOnClickListener {
            launcher.launch(
                   config
            )
         }
