I have developed an hybrid with combination of Sencha Touch2.3 and Phonegep. It has barcode scanner feature. It is working fine with iPhone 3 and iPhone 4. It is not working consistently in iPhone 5s. Sometimes it scans immediately and doesn't scan full the barcode.
I am sure there weren't problems with Sencha Touch 2.3 and I am using latest version of PhoneGap.
I don't know how to fix this. I tried looking in google, I could not find any useful answers.

I am working on an barcode reader app which currently uses zbar sdk, i works like magic on iphone 4G but does it also works with ipod touch?????
if it does'nt then is that any other api which supports barcode reader in ipod touch.
Thanks
Yes it does. For QR codes its quite fast. But for UPC, you may have to be a bit specific about the distance from where you are scanning though(scan from 30cms). Read this for further info.
I started a GWT project targeted for iPhone (and later for other mobile platforms). Now there's a problem:
* I can use Safari on iOS to test it, but I have to compile my app which takes a while even after performance optimizations mentioned for example how-do-i-speed-up-the-gwt-compiler;
* I can NOT use Safari in gwt-debug mode to make quick tests without compilation Java to JS because there's no GWT plugin for Safari on iOS.
So: is there a workaround for fast test of GWT app on iPhone?
Same thing here. I have been developing a GWT app using PhoneGap to bring it to iOs and Android. I ended up just using Firefox for development, every once in a while letting the app run in the iOS Simulator (coming with XCode). But since the app is using geolocation via PhoneGap, there was no way around installing it on the phone every once in a while to make sure it behaves.
I found some mobile dev emulators, one that is coming to my mind is called Ripple. There are others out there, but non of them worked for me.
I am starting a project with PhoneGap and it will work on iPhone and Android devices. The question is how to implement support for different screen sizes and resolutions.
For example, I have an icon inside the application: small waves to run some action. What size of this icon should be to be shown well in all possible devices (iPhones/Androids). Should I include several versions of the same image?
The same question about text. How can I be sure the text will be readable and will stay in line on different devices?
thank you
If you are a MAC user you could give the new dreamweaver 5.5 a shot. It will structure your app and even build a debug version for testing. You can do this with either the ANDROID SDK or the iOS sdk. Of course, it will work on a PC as well but there is not support for the iOS sdk.
Using the Adobe Dreamweaver 5.5 it has specific mobile framework to recognize jqm or jqtouch and inserts phonegap.js on build into the packaged product. It also allows you to scale the testing screen for the different sizes of mobile devices. From android, iphone, to ipad(and more)
Here is an example: Dreamweaver with phonegap support
I want to implement read/scan bar code in my iPhone application. I would like to know how to implement it into our iPhone app and also some links and example code and apps to check out how it works.
You can use our free app pic2shop as an external barcode scanner (from a web page or from another app). Here is a demo and detailed info: http://www.pic2shop.com/developers.html
It works even on non-autofocus devices (iPad2, iPod Touch, iPhone 3G and many Android phones).
I am newbie to iPhone application. But recently I saw a post asking for Barcode Reader for 3G iPhones. And people(including me) have referred to zxing which works on 3GS or later and if you want to make an appication for 3G then better you buy it from QuickMark or RedLaser to get 3g scanning.
So I planned something and need several information from you all
There are lots available on appStore. One of them is pic2shop(Which is a free application).
But what I want to know is:
What exactly is it done to recognize the barcode and generate code?
Is there any website or link to which when image of barcode is send will respond with the code generated or any API which does the same i.e. Taking picture and generating code.
And Secondly From Where does we get the information about the produce related to that barcode code.
Hi we recently had a product which required bar code scanning functionality, in the end after evaluating a lot options we went with zBar but it does not work on iPhone 3G it requires 3GS or above.
zBar is an open source SDK you can download it from sourceforge.
What we're doing right now is scanning bar codes using the zbar SDK & then calling upcdatabase.com API through xml-rpc to get the information about the product back.
And its working pretty well.
If you do not want to pay redlaser or others for SDK I would recommend using this approach. But of-course the downside is iphone 3G is not supported which I think does not represent many devices & also recently Apple has also dropped its support for its upgrades as iPhone 3G users will not be able to upgrade to iOS 4.3.
I actually own a 3G iphone & its very slow on iOS version 4.0 .
