It as easy as implementing a listener and calling another activity.

Implement or create an instance of DocumentScannerEventReceiver implementation.

Java

// Java
@Override
public void onProcessingCompleted(Context context, Document document) {
    // Background document processing has successfully finished
         document.getDocumentImage();
}
 
@Override
public void onProcessingFailed(Context context, ScannerError error) {
// Journey failed check Scanner Error possibilities, in JavaDocs.
}
 
@Override
public void onProcessingCancelled(Context context, ScannerError error) {
// Journey was cancelled by user input (onBackPresed)
}

Kotlin

// Kotlin
private val response = object : DocumentScannerEventReceiver() {
        override fun onProcessingCompleted(context: Context, result: Document) {
            // If Scan was successful document object will be returned here.
            // Document object contains document image and minimal clarification of the document if document was recognised.
        }
 
        override fun onProcessingCancelled(context: Context, scannerError: ScannerError) {
            // Returned when customer canceled journey, most probably onBack click.
        }
 
        override fun onProcessingFailed(context: Context, errorCode: ScannerError) {
            // Failure from which we could not recover.
        }
    }

//Register before call
DocumentScannerService.registerEventReceiver(context, implementation);
 
//Unregister after call
DocumentScannerService.unregisterEventReceiver(context, implementation);

Create an intent with destination activity is DocumentScannerActivity and start it.

// Create intent to start scanner activity
Intent myIntent = new Intent(MyActivity.this, DocumentScannerActivity.class);
startActivity(myIntent);
