Integrated barcode scanner in App Inventor
<p>I am creating an app that is scanning a barcode and exporting the results to a spreadsheet online. But I would like to know how I can integrate the scanner into the app using App Inventor as currently my app is opening the Zxing application to scan the barcode but I want it to scan within the app or even have it running in the background once on the scanning page. </p>

<p><a href="http://i.stack.imgur.com/EVf9J.png" rel="nofollow">These are my current coding block which allow the scanner to open externally</a>

<p>Could someone advice me on how I can get it to be integrated into the app itself without the user having to install Zxing or any other additional scanning application. </p>
