Our team is coding an Android QR code scanner app using ZXing 3.4.0 library and we need to scan rather complex QR code like below. We've been testing and found that the scanning is not stable sometimes it could scan the QR code sometimes it can't.
My question is how to optimize the scanning to ensure fast and stable outcome? Should I turn on TRY_HARDER? Should I use Binarizer? If so, which type - GlobalHistogramBinarizer or HybridBinarizer? Should I scan the QR closer to the phone (enlarging the QR code in the camera view)? Anything else I should do?

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'm working on a project which will to scan pdf417 barcodes, am developing this application using Rhodes specially for Android and iPhone. As I came to know that Zxing is one the useful api to scan pdf417 barcode for Android.
Can we Integrate Zxing with Rhodes ?
What is the procedure?
Please let me know if anyone gone through this.
-Thanks.
Rhodes uses Zxing in its Barcode class (http://docs.rhomobile.com/en/5.0.38/api/barcode), so there is support out of the box for some of Zxings features. For example for QR Codes and Code128 it works right away. However, not all types of Barcodes are supported on all platforms, so you should try out if pdf417 is supported on Android and IOS.
If it is not you can still write a native extension. It's actually not that hard. The documentation is relatively good (http://docs.rhomobile.com/en/5.0.38/guide/native_extensions). However, in my opinion it misses how to start and return to activities (via startActivity or startActivityForResult). But luckily the source code of how they implemented the Barcode class is open (https://github.com/rhomobile/rhodes/blob/3-5-stable/lib/extensions/barcode/ext/barcode/platform/android/src/com/rhomobile/barcode/Barcode.java) so you can take it as a basis for your own native extension with a scanning engine which supports pdf417.
I am trying to do an app to create a final QR code for the information of multiple barcodes
that I have scanned.
I am wondering how would you import the ZXing lib to your code?
Assume that user already has ZXing scanner in their mobile, can I just connect with the app to generate the barcode without importing all the lib since it will make my app heavy?
For importing , QRencoder.java from ZXing, what are the necessary part of codes that I need?
Or is it even possible?
I found this two months ago : http://damianflannery.wordpress.com/2011/06/13/integrate-zxing-barcode-scanner-into-your-android-app-natively-using-eclipse/
And I have tried installing that apache but it is so painful process for me. So is there any other ways around?

Yes, just use Intents. You don't need any code beyond the bit of integration code here: http://code.google.com/p/zxing/wiki/ScanningViaIntent The same class has methods for encoding a barcode on screen.
