Barcode scanning is one of the most potentially useful resources you will come across on the Android platform. The ZXing (Zebra Crossing) project is bar far the easiest and most effective way to implement barcode scanning for most development purposes. Since the project is open source, you can either use the code within it to implement your own custom scanning functions or can access the library classes via Intent, leaving the details up to the ZXing classes.

Usage
For a detailed introduction to using barcode scanning in Android apps, see this tutorial I wrote for Mobiletuts+: Create a Barcode Reader and this series on creating a book scanner app for more of a real-world example: Create a Book Scanning App. For a comprehensive reference, see the ZXing docs: Scanning Via Intent.
The simplest way to include scanning functions in your apps is by Intent. You simply copy the Intent Integrator and Intent Result classes into your app and call on them in your own classes.
To use the ZXing integration classes in your app, import them to the Activity class you want to access them in, for example the following if you use the default package names:You can then launch the scanner in your Activity class as follows:If the user does not have the ZXing barcode scanner installed on their device, they will be prompted to download it from Google Play at this point, so you don't have to carry out any checking of your own. When you initiate a scan, you can optionally pass a parameter indicating the types of barcode you want to scan - the parameter should be a Collection of Strings.
You can then retrieve the results of the user's scanning operation inside the onActivityResult method for your class:The Intent Result object will now provide access to the content and format of the returned scan data if there is any:
Options
While using the integration classes is by far the simplest way to utilise the ZXing functionality, there may be times when you need to implement your own bespoke scanning functions. If so, you can download the source code. It's probably only advisable to do this if you have no other option, since using the integration classes gives your app access to the continual updates within the ZXing app without you having to update your own code.
Applications
As usual, Stack Overflow has the answers to lots of common questions and problems with ZXing.
Intigrating ZXing-BarCodeScanner In to your Android Application
Step One: Obtain the zxing src code
The src can be found at http://code.google.com/p/zxing/source/browse/trunk
Specifically you only need the android/ and the core/ projects. Use svn to checkout these to your local hard-drive.
Step Two: Build zxing core using Apache Ant
You will need to build the core project into a jar file using apache ant (download from here http://ant.apache.org/ivy/download.cgi).
Using a shell or cmd prompt navigate to the root directory of the downloaded zxing src and execute ”ant -f core/build.xml”.
This will produce a file core/core.jar which we will use in the next step.
Step Three: Build ZXing Android using Eclipse
Create a New Android Project (File –> New –> Android Project).
Set the project name to ZXing (or similar).
Select the “Create project from existing source” radio button
Click “Browse” and navigate to the android project that you downloaded from zxing and click “OK”
Select “Finish”
The project will not currently build. We need to add the core.jar file (that we produced in the previous step) into our project.
Right-click on ZXing project –> properties –> Java Build Path –> Add External Jars –> Navigate to and select core.jar –> Open –> OK.
Actually, while we’re here we should do one more very important thing!
Right-click on ZXing project –> properties –> Android –> Scroll down and check/tick the “Is Library” checkbox –> OK.
Step 4: Include ZXing Android into your project.
Within Eclipse, Right-click on YOURPROJECTNAMEHERE project –> properties –>Android –> Scroll down to Libraries section –> Click Add –> Select ZXing (which should appear as an option as a result of completing previous step).
Next, in some trigger function e.g. button press within your code you should add:
Intent intent = new Intent('com.google.zxing.client.android.SCAN');
intent.putExtra('SCAN_MODE', 'QR_CODE_MODE');
startActivityForResult(intent, 0);
In the same activity you’ll need the following to retrieve the results:
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode 0) {
if (resultCode RESULT_OK) {
String contents = intent.getStringExtra('SCAN_RESULT');
String format = intent.getStringExtra('SCAN_RESULT_FORMAT');
// Handle successful scan
} else if (resultCode RESULT_CANCELED) {
// Handle cancel
}
}
}
Almost there! One of the current limitations of Android Library projects is that it will not pull anything from AndroidManifest.xml into your project.
So if we try to invoke the above code we will receive a runtime exception because your Android app has no idea how to handle the scan intent.
To fix this you just need to copy the following into your AndroidManifest.xml:
<activity android:name='com.google.zxing.client.android.CaptureActivity'
android:screenOrientation='landscape'
android:configChanges='orientation|keyboardHidden'
android:theme='@android:style/Theme.NoTitleBar.Fullscreen'
android:windowSoftInputMode='stateAlwaysHidden'>
<intent-filter>
<action android:name='android.intent.action.MAIN'/>
<category android:name='android.intent.category.DEFAULT'/>
</intent-filter>
<intent-filter>
<action android:name='com.google.zxing.client.android.SCAN'/>
<category android:name='android.intent.category.DEFAULT'/>
</intent-filter>
</activity>
And as Columbo would say, “Just one more thing!”.
Add this permission to the top of your AndroidManifest.xml:
<uses-permission android:name='android.permission.CAMERA'/>
EDIT: You need to do yet one more thing!
You need to add the core.jar (produced in Step two) to your new project
(Right-click your project –> Properties –> Java Build Path –> Add External JARS… –> Select core.jar –> OK).
Thanks

Blackberry desktop software windows 7. ZXing Android Embedded. Barcode scanning library for Android, using ZXing for decoding. The project is loosely based on the ZXing Android Barcode Scanner application, but is not affiliated with the official ZXing project. Features: Can be used via Intents (little code required). Can be embedded in an Activity, for advanced customization of UI. Taal songs mp3 free download. The award-winning Scandit Barcode Scanner SDK transforms smartphones, tablets and wearable devices into enterprise-grade barcode scanning tools for consumers and employees. The Scandit Barcode Scanner Demo app showcases the barcode scanning performance of the Scandit Barcode Scanner SDK. Use this demo app to see how fast and reliable the Scandit Barcode Scanner. Android sdk full download offline windows 10.
ZXing can scan numerous barcode formats in use on a variety of products, including EAN/ ISBN, UPC, QR codes, Data Matrix, Aztec and more. The resource is implemented in Java, with Android-specific classes available for quick use in your own projects.Usage

Applications
Integrate Zxing Barcode Scanner Into Your Android App Download
There are lots of potential applications of barcode scanning in Android, from inventory and warehouse functions to shopping apps. Your apps need to respond to the data within a barcode in a relevant way, so your code must examine the scan results before attempting to use them in further processing, for example opening a URL in the browser.As usual, Stack Overflow has the answers to lots of common questions and problems with ZXing.
