Very often I will be browsing the internet on my HTC Evo. I constantly come across websites that reference an android application, and provide a QR code of the URL to download the application from the marketplace. Those same sites very rarely provide the actual link to the application in any other form.

I am looking for an android app that will read QR codes that are on the phone itself. Ideally, this application would utilize the "share" functionality of the built in browser in such a way that I merely hold my finger down on an image of a QR code, select "share" from the resulting menu that comes up and select the app to send the image of the QR code to.

Are there any apps out there that do this or come close to the above functionality? If not, I will likely try to built my own, as I believe the QR decoding libraries are freely available. I just don't want to reinvent the wheel.

Interesting idea to use the "share" function to pass it an app that could read/interpret the QR code. –  Bryan Denny Nov 2 '10 at 18:36

Thank you for this question. Its always baffled me why all these sites only put qr codes which are completely useless to those of us browsing on our phones. Seems a little perverse. "Hey, you've got this great internet enabled device and we've got a great link to share with you, so get off your device and go open this page on your pc so you can follow this link by taking a picture of it with your phone!" –  Matt Nov 2 '10 at 18:57

Please nag the owners of those sites to make the QR-code a link to the market. If only 1% of the users that are angry about this would actually say anything, this would change quickly and that would be a much better solution. –  hstoerr Sep 28 '11 at 18:27

You can do this from the Browser itself using "QR Droid". Search for it and install it. After that:

  • In the Browser, long-click the image and select "Save image"
  • After downloaded, open image from notification bar
  • Select Menu > Share > "Decode with QR Droid"

Sorry for the late acceptance of your answer. QR Droid is just what I was looking for. Thanks! –  John Kramlich Dec 17 '10 at 8:40

Here's an app that reads and decodes qr codes from a file...

Also, you can bookmark this web based reader: http://zxing.org/w/decode.jspx then when you come across a qr code, long click on it and copy the image url, then paste it into this page.
