On an HTC Hero, this EXTRA_OUTPUT doesn't even work. It doesn't put your picture in the file you specify, but it hands it to you thru a Mediastore uri. Apparently, the only way to get a full size picture is to do all camera handling in your app instead of using the IMAGE_CAPTURE intent.

I think Google have missed a trick on this one. They have defined standard intents for media capture, but not specified standard responses (ie. the "data" parameter in the onActivityResult Activity callback method). Other Android vendors (e.g. HTC Hero) have created their own Camera applications that handle the standard IMAGE_CAPTURE intent, but return different data & have different ways to save/return the image information. All I want is to be able to fire a IMAGE_CAPTURE intent from my own app, and get back a Uri reference to the captured image. Simple. I have no requirement to further manipulate the image .. I just need the Uri to store in my app's database for future reference.

Rhodes is an open source Ruby-based framework to rapidly build native apps for all major smartphone operating systems (iPhone, Windows Mobile, RIM, Symbian and Android). These are true native device applications (NOT mobile web apps) which work with synchronized local data and take advantage of device capabilities such as GPS, PIM contacts and calendar, camera, native mapping, push, barcode, signature capture, and Bluetooth.

Consumers want immediate access to what’s relevant and QR codes are being used to make that possible.

Bar codes are linear one-dimensional codes and can only hold up to 20 numerical digits, whereas QR codes are two-dimensional (2D) matrix barcodes that can hold thousands of alphanumeric characters of information. Their ability to hold more information and their ease of use makes them practical for small businesses.

When you scan or read a QR code with your iPhone, Android or other camera-enabled Smartphone, you can link to digital content on the web; activate a number of phone functions including email, IM and SMS; and connect the mobile device to a web browser.
