In my android application I need the QR code reader, so after lots of search, I ended up with the point that there is no need to implement QR code encode/decoder from scratch and that I can use ZXing library to do the task. but now im stuck with HOW to integrate ZXing library in my code, and then how to retrieve the scanned data into a string to my project? I know, this question might be a stupid one but Im newly introduced to such a topic.
Thanks alot.
By far the simplest, if you aren't in a position to write a full scanning app, is not to write a full scanning app. Integrate with an existing one by Intent in 10 minutes: https://code.google.com/p/zxing/wiki/ScanningViaIntent
The ZXing wiki has instructions on how to do this easily.
Basically you include some simple code that starts the ZXing Android app and then retreive the result in onActivityResult().

I have an Android Application where I use ZXing Library to scan barcodes and get the data written in them. In addition, I would like to save the photo of the scanned barcode image that ZXing scanned. If one looks closely, you can see that the ZXing Library "freezes/pauses" the camera input when it manages to read the barcode.
I've seen this question from 2 years ago where someone attempted to play with the ZXing library. I tried to extend CaptureActivity instead of Activity, however, I am getting the error:
Cannot inherit from final
'com.google.zxing.client.android.CaptureActivity'
and now I'm unsure on how to go about this.
Is it possible to get the Image that the Barcode Scanning Application of ZXing reads? Did ZXing eventually incorporate this feature and patch it? I can't seem to find any guides online on how to get the image that was "captured". It will make my Android Application run more seamless.
While leading for years, you might want to consider using Google's API, then you can save the camera snapshot yourself.

I'm going to develop mobile app that using QR Code to make easy for the user to view the information detail of the item. Anyone have reference to help me to create QR Code?
Just use the Zxing library, it is an open-source, multi-format 1D/2D barcode image processing library implemented in Java and it supports QR Code.
There are very good tutorials explaining how to create apps to read QR codes from scratch using Zxing library.
You can use Zbar or ZXing. For ZXing tutorial is Here
I want to Create an application which can read the Ba Codes. I want to do this through my on application not using third party applications like 'ZXing'. Please any coding help or tatorial...
I have already done an Android application by scanning directly a barcode with my app. I have used Zxing barcode sources to take functionnalities that I want and it's easy to make your own application which scans barcode.
More particularly, what you have to do is to design a screen which can take photos, then you just need to use the Camera object and when you have an image captured, put it in Bitmap format in parameter of one ZXing method. Then you will have the result and you can display it like you want.
If you have more specific questions about this, don't hesitate to ask. I can retrieve my code to help you.
If you go here: http://code.google.com/p/zxing/wiki/ScanningViaIntent
and follow the explanation, in order to add the class and code described in the site.
Once you've implemented it the scanner added ..
I suggest that you check out the free Scandit barcode scanner SDK for Android. It comes with a step-by-step guide, example code and instructional video how to get started and it also works with low-end Android devices that have no autofocus camera and/or limited resolution.
If you are interested in converting the UPC numbers scanned to product names, there is also a product API.

I need to write an android aplication to create/generate a barcode using a string with the value to show.
The android app had to show a pic with the barcode to be scaned with other phone.
I read a lot from internet and everybody recomend to use Zxing for that, but i can't find some tutorial about how to use Zxing to create barcodes on android.
I have experince using Zxing with Android-Integration to read QR Code.
I have to use the same to create barcode?
Can i use Android-Integration?
Thank you very much
Sorry for my poor english
Scanning via Intent should be all you need: https://github.com/zxing/zxing/wiki/Scanning-Via-Intent
Hi I am developing an application for the android htc hero. I am looking into ways of using the inbuilt camer to read 2D barcodes and extract the string returned from the barcode. I have only recently begun working with the android sdk but I do have a programming background from working on projects with java. I am curious to know what the best way to read the 2D barcode would be. I have some sample applications that read the barcode but they are all .apk files and have no source or library that i can work with. to give you a better idea of what i am trying to accomplish this site allows the generation of 2d barcodes made up of the data you desire here
Any replies would be greatly appreciated.
Android programs can interact with eachother using intents. Intents are a little like remote procedure calls: you ask the other program for a certain action (e.g. scan a barcode) and the other program will perform this task for you. The result is returned when the task is complete.
If the user has installed the ZXing Barcode Scanner, you can just use an intent to scan a barcode. The Barcode Scanner will then start, let the user scan the code and return the result to you.
More information about this scanner can be found on the Google Code page of this project: http://code.google.com/p/zxing/wiki/ScanningViaIntent
I'd look at this open source Android project: http://code.google.com/p/zxing/
For fellow Google search travelers, there is a 2012 post on the android developers blog on how to use intents with the example of barcode scanning :

As far as I know for decoding barcodes (apart from the algorithm) you need to know the (relative) widths of white and black bars. For that, you would have to rotate the barcode to a horizontal position and then detect the widths.
(Ok, the ZXIng stuff advised by others outperforms this manual hacking)
