See more:

i went throght this web site https://github.com/journeyapps/zxing-android-embedded[^] and have implemented a barcode scanner. but i am not able to fetch the value after it has been scanned

the code i used to implement the scanner is as follows

Java

IntentIntegrator integrator = new IntentIntegrator(MainActivity.this);
               integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
               integrator.setPrompt("Scan a barcode or QR Code");
               integrator.setCameraId(0);  // Use a specific camera of the device
               integrator.setBeepEnabled(false);
               integrator.setBarcodeImageEnabled(true);
               //integrator.addExtra(key,value);
               integrator.initiateScan();

in onActivityResult

Java

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
        if(result != null) {
            if(result.getContents() == null) {
                Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
            } else {
                Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();
            }
        } else {
            // This is important, otherwise the result will not be passed to the fragment
            super.onActivityResult(requestCode, resultCode, data);
        }

    }

on running the app i get an error

C#

Error:(50, 52) error: package com.google.zxing.client.androidlegacy.camera does not exist

i have imported the following library into my gradle file

JavaScript

compile 'com.google.zxing:core:3.2.0'
    compile 'com.journeyapps:zxing-android-embedded:3.0.3@aar'

now how do i fetch the scan value? please guide me to achieve this

Try in this way:

Java

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
   if (requestCode == 0) {
      if (resultCode == RESULT_OK) {
         String contents = intent.getStringExtra("SCAN_RESULT");
         String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
         // Handle successful scan
      } else if (resultCode == RESULT_CANCELED) {
         // Handle cancel
      }
   }
}
