Try the zxing library : http://code.google.com/p/zxing/
you can use either

I have been trying to build an Android application in which i need to include a qr scanning feature. And After scanning that qr code it should provide an drop down menu to choose categories to proceed with. How can i achieve this? I'll be using java to build that application. Please consider helping this.
Use this library for QR scanning

It will solve your problem
Firebase now has a Barcode Scanner feature, including QR Code, it's free and run 100% on device.
i am at beginner level in android. i want to develop an app which scan QR code using camera and shows the result of QR code. There are many solution there but every time i try code the error appear or exception is there. i want complete step by step process in android studio or tutorial link
I highly recommend you to check Udacity, they have awesome free courses for beginners and intermediate developers. Also they have Android Developer Nanodegree and one of it's projects is to create a Barcode scanner app, which is very similar to scanning QR code.
Also you could try using library like this to implement QR-scanner functionality, but using library won't improve your knowledge.
You can use the ZXing library for reading the bar-codes and parsing the contents. Here's a good tutorial.

I am looking for a detailed tutorial on QR code generation in Android. Kindly, let me know if ZXing is the only possible solution or there are other options.
You can use the Zxing Library for QR purpose projects.
Complte list of examples are available here,
Android Barcode scan Using Zxing Library
Integrating ZXing in your Android App as standalone scanner
I want implement an activity that when starts, capture the QR code by camera, and than decode it. Can I do this without installing an other app on my tablet?
I seen zxing, but I don't understand how implements it..
Yes, you can. You will have to:
- initialise camera and start preview mode
- wait for preview image and process it
- pass it to zxing library to decode.
Good starting point: zxIng demo applications - sources are available
Use opensource QR code projects and use them for your app. zxing is one
Try using latest zxing liberary.
You can use it by two ways,
Add the zxing library to your workespace and make it as liberay project.
Add all the file of the zxing liberary to your project.
The second option is much easier. You have to make changes in CaptureActivity according to your requirements. Its very easy.
I want to make an Android app that uses the camera to take a photo of a barcode for a product to get the number of barcode, but I have some problem to make the implementation.
The main question is how can I use the camera to take a picture to recognize the id of this barcode without using any external application.
Thanks for your help!
You should try Zxing library, the library contains Barcode Scanning feature.

Why won't you use the external application? This is the power of Android apps - they can use each other functionality, which is implemented perfectly in their app.
yes yu should use the zxing tool this is an open source you can use in your code too, here : http://code.google.com/p/zxing/
downloads/list. download the source code from main site and see manual it will give you the instruction too
