Hi Tim, I've been exploring into extensions for PlayBook. I was wondering if you could assist with me some tips. This is for QR code scanner. Going through latest camera API I found that standard function launch was used to invoke a camera to capture image/video. What i would like to know is, will there be any way to use the standard functionality attachCamera with WebWorks for PlayBook in extensions. Normally a QR Code Scanner works when a camera is scanning an image. I think this is possible using the attachCamera function only. Any tips on this will be really helpful.

I'm personally not familiar with the attachCamera funcationality.. I have heard that there are some open source QR barcode scanning ActionScript libraries out there that you should be able to plumb in as an extension.

Yes, I got hold of one such library and was able to implement it. But what I'm trying now is to scan the QR Code on the go when the camera is still open. The existing one scans images taken by a camera. An actual QR Scanner works the other way around. So I was thinking of getting some help from RIM guys

Hi TIm,

A quick question. When will the next release of PlayBook be available? Is it by mid October as listed in the roadmap or any intermediate release.

Also, may I know how the QR Code Scanner is expected to work for the PlayBook(the workflow). A small description will help me out.

Hi Praveen,

Right now we don't have another WebWorks SDK for Tablet OS planned until mid October.  That could change as the roadmap is tentative and we're constantly thrown curve balls

We don't currently have the QR Code scanner on a deliverable release as of yet so we haven't really put much thought into exactly how it will work.

Hello Tim,

I a very new to the board, my first post.

Question, i see that this is no direct support for real time QR code scanning for webworks tablet.

but i a interested in such a function for smart phones, does it exist? and should i assume that both tablets and smart phone api's are par where features are concerned ?

Hi ksolo,

Praveen has been working on one he may be able to share... Currently we don't have an official API as part of the WebWorks SDK

Re: help! my apps are stuck downloading...

We're writing an app that uses the Microphone api, writes potentially large files, needs to encrypt them, slice them up and join them back together.

As you can imagine, we're running into issues working with files of any length (2 x 15 minute AMR recordings == 3 mb). We're running out of memory trying to join files and are likely going to have to write an extension to optimise our data usage.

It would therefore be really handy if WebWorks had some APIs to allow us to detect Memory (not Disk) and CPU usage.
