I would like to get product information by scanning the barcode. is that possible
if the information is in json it will be great.
I don't know what are you exactly looking for, you need to give more information, but you have a bunch of apps in the Play Store like "Barcode Scanner"
If you are looking for a library to integrate into your project, then you have a few options. Two of the most popular ones are next:
ML Kit: https://developers.google.com/ml-kit/vision/barcode-scanning/android
ZXing: https://github.com/zxing/zxing
Logically besides the libraries you still need to code a way to pass images to the libraries. So, to code a camera, use the device system camera, or an image picker.

So maybe this is not the right way to ask in Stackoverflow but I will try my best. So I want to create small Android app which can scan barcodes and save them into sql database immediately. I don't have any idea about making Android app. I tried searching in Google but it is hard to find this exactly.
I'm fairly new to this, too but I will do my best to help you. As far as I can tell, the only way to actively scan something is to take a picture of it, then feed that picture into your database. Look into camera functions for Android instead of a scanner, as they are usually looking for a different type of input, such as Strings. Google Camera API, and look at the database option.
I need a barcode scanner for my mobile apps which works really fast and also with bad lightning conditions. As I only need to store UUIDs and not complete URLs etc., I guess there should be a possibility to limit the value range and therefore make the QR codes better recognizable. Is there a format which supports this?
I also find the WhatsApp QR-Code scanner very fast but I didn't find what they are using exactly...
One introduction might be this blogpost. It's based on Google's mobile vision api under the namespace com.google.android.gms.vision.barcode. It's fast, robust and easy to work with.
And I would also up the error correction level of the generated QR-codes if possible... But try the project linked in the blogpost first to see if you even need to.
You can use this library barcodescanner
With bad lightning conditions you can activate the flash, in the library there is all about it.
I want to do Face recoginition (Not Face Detection) in my Android and iOS app. I have studied a lot on Web and found following possible solutions:
1.) openCV: I don't want to go into writing my own API using this. Also, I don't have prior experience in JNI for Android.
2.) Betaface API So far this is good.
3.) Sky Biometrics is also Good.
Now, I am searching for the solution from 3-5 days and came to know that I can use above API (so far I have decided to purchase license for Sky Biometrics). And this API will provide me a list of Features for the faces it recognised.
But, Now I am confused That how to use these features and save in my local data base to recognise faces from the pictures.So My queries are following
1.) How to convert Face features to Actual working Face recognition API means What is the actual algo or solution I can use to merge diffrent face features of a same person to identify him correctly.
2.) Uploading images and then creating database for Face-features set is a very time taking process. Do any one knows any Android/iOS Face Recoginition SDK to do this so that I can do this accurately and timely with no or less time taking process.
3.) Both solution-2 and 3 can be used with Images. Is there any other solution is available which can do the same with less efforts but with more accuracy.

Finally I am using Rekognition API. And this is good enough to serve my purpose.
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.
[Disclaimer: I am a developer at Scandit]
I am developing an barcode scanning application using zxing(in eclipse). I have read many stack overflow threads about developing.
I saw mostly things like, need to use a barcode scanner app for handling the decoding the barcodes and QR-codes.
Is there any option to do that also using the code like capturing the image using camera and then read? We need to create an independent app. Can anyone please help me? Thanks in advance and expecting a detailed reply if possible.
One of the biggest advantages of the Android platform is that you can leverage other apps to provide increased usefulness for yours without a ton of work. In essence yes you could rewrite the bar-code app, but a lot of people will ask why would you want to reinvent the wheel? Now it is true that the zxing process is open source so you can look at their entire program, however I found it more effective to just leverage what was already there.
If you place a check in the program to see if the system can handle the action, you can recommend people get the bar-code scanner to unlock that functionality.
This process is encouraged by the folks at Google. However, as always, you can always try to rewrite it from scratch.
