You will need https://f-droid.org/packages/com.google.zxing.client.android to be installed to use this. First visit <a href="https://send-to-computer.appspot.com">https://send-to-computer.appspot.com</a> on your computer and make sure popup blocking is disabled. Scan the barcode given on the screen (the app remembers the unique id at the end of the url so that it can identify your requests for web pages). Choose Open in Browser and choose Send to Computer (you may have to scroll). You are now setup and can send webpages to your computer via the browser share menu. The computer browser checks every two minutes for requests so you might have to wait a little. The source code is also available for the server side of things.
