Scan barcodes and QR codes

Below you will find information on how to start and manage the Point Smart scanner for reading barcodes and QR codes.

Barcode

To begin reading QR codes of the Point Smart, use the initBarcodeScanner feature of the CameraScanner class.

This process uses a camera request through startActivityForResult, and the method onActivityResult must be implemented in the activity to handle the reading response.

Check the example below:

          
val cameraScanner = MPManager.cameraScanner
cameraScanner.initBarcodeScanner(this@YourActivity)

        
          
final CameraScanner cameraScanner = MPManager.INSTANCE.getCameraScanner();
cameraScanner.initBarcodeScanner(this);

        

QR code

To begin reading QR codes of the Point Smart, use the initQRCodeScanner feature of the CameraScanner class.

This process uses a camera request through startActivityForResult, and the method onActivityResult must be implemented in the activity to handle the reading response.

Check the example below:

          
val cameraScanner = MPManager.cameraScanner
cameraScanner.initQRCodeScanner(this@YourActivity)

        
          
final CameraScanner cameraScanner = MPManager.INSTANCE.getCameraScanner();
cameraScanner.initQRCodeScanner(this);

        

Process scanner response

To manage the response of a QR code or barcode scanning activity, use the handleQrResponse feature of the CameraScanner class from the onActivityResult method.

This function processes the scanner result from the camera, validating the response and invoking the appropriate callback based on the result. It receives an MPResponse object with a [CameraScannerResponse], representing the reading response.

This method simplifies the process of handling the responses from the QR code or barcode scanner in the onActivityResult method, processing the scanner result from the camera, validating the response, and invoking the appropriate callback based on the result.

Check how that takes place below.

          
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
   super.onActivityResult(requestCode, resultCode, data)

   val cameraScanner = MPManager.cameraScanner

   cameraScanner.handleScannerResponse(this, resultCode, data) { response ->
       response.doIfSuccess { result ->
           // Manage successful response
           val status = result.status
           val message = result.message
           // ... Do something with the response
       }.doIfError { error ->
           // Manage the error in the response
           val errorMessage = error.message
           // ... Do something with the error
        }
    }
}

        
          
@Override
protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
 super.onActivityResult(requestCode, resultCode, data);

 final CameraScanner cameraScanner = MPManager.INSTANCE.getCameraScanner();
 final Function1<MPResponse<CameraScannerResponse>, Unit> callback = (final MPResponse<CameraScannerResponse> response) -> {

   if (response.getStatus() == ResponseStatus.SUCCESS) {
     final CameraScannerResponse cameraScannerResponse = response.getData();
     // Manage successful response
     final String result = response.getData().getMessage();
     // ... Do something with the response
   } else {
     // Manage the error in the response
     final Exception errorMessage = response.getError();
     // ... Do something with the error
   }
   return Unit.INSTANCE;
 };

 cameraScanner.handleScannerResponse(this, resultCode, data, callback);
}

        
FieldDescription
resultCode (Int)Value of the resultCode in onActivityResult.
resultData (Intent?)Date result in onActivityResult.
MPResponse<CameraScannerResponse>Object [MPResponse] that includes the status, the error (if any), and the details in case of success, which contain an CameraScannerResponse object.
status (CameraScannerStatus)Defines the status of the response. It can be "Ok" (it read it successfully), Error (something went wrong and it was cancelled) or Unknown (something went wrong).
message (String)Defines the response message received by the scanner. If it’s ”Ok”, it will have the result of the reading of the code.
