Android library projects that provides easy to use and extensible Barcode Scanner views based on ZXing and ZBar.
I am giving github link with this example am just adding details but any confusion please comment below i would happy to reply it back

ZXing
Installation
Add the following dependency to your build.gradle file.
compile 'me.dm7.barcodescanner:zxing:1.8.4'Simple Usage
1.) Add camera permission to your AndroidManifest.xml file:
<uses-permission android:name="android.permission.CAMERA" />
2.) A very basic activity would look like this:
public class SimpleScannerActivity extends Activity implements ZXingScannerView.ResultHandler {
private ZXingScannerView mScannerView;
@Override
public void onCreate(Bundle state) {
super.onCreate(state);
mScannerView = new ZXingScannerView(this); // Programmatically initialize the scanner view
setContentView(mScannerView); // Set the scanner view as the content view
}
@Override
public void onResume() {
super.onResume();
mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
mScannerView.startCamera(); // Start camera on resume
}
@Override
public void onPause() {
super.onPause();
mScannerView.stopCamera(); // Stop camera on pause
}
@Override
public void handleResult(Result rawResult) {
// Do something with the result here
Log.v(TAG, rawResult.getText()); // Prints scan results
Log.v(TAG, rawResult.getBarcodeFormat().toString()); // Prints the scan format (qrcode, pdf417 etc.)
// If you would like to resume scanning, call this method below:
mScannerView.resumeCameraPreview(this);
}
}
Please take a look at the zxing/sample project for a full working example.
Advanced Usage
Take a look at the ScannerActivity.java or ScannerFragment.java classes to get an idea on advanced usage.
Interesting methods on the ZXingScannerView include:
// Toggle flash:
void setFlash(boolean);
// Toogle autofocus:
void setAutoFocus(boolean);
// Specify interested barcode formats:
void setFormats(List<BarcodeFormat> formats);
// Specify the cameraId to start with:
void startCamera(int cameraId);
Specify front-facing or rear-facing cameras by using the
void startCamera(int cameraId); method.

ZBar
Installation
Add the following dependency to your build.gradle file.
compile 'me.dm7.barcodescanner:zbar:1.8.4'Simple Usage
1.) Add camera permission to your AndroidManifest.xml file:
<uses-permission android:name="android.permission.CAMERA" />
2.) A very basic activity would look like this:
public class SimpleScannerActivity extends Activity implements ZBarScannerView.ResultHandler {
private ZBarScannerView mScannerView;
@Override
public void onCreate(Bundle state) {
super.onCreate(state);
mScannerView = new ZBarScannerView(this); // Programmatically initialize the scanner view
setContentView(mScannerView); // Set the scanner view as the content view
}
@Override
public void onResume() {
super.onResume();
mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
mScannerView.startCamera(); // Start camera on resume
}
@Override
public void onPause() {
super.onPause();
mScannerView.stopCamera(); // Stop camera on pause
}
@Override
public void handleResult(Result rawResult) {
// Do something with the result here
Log.v(TAG, rawResult.getContents()); // Prints scan results
Log.v(TAG, rawResult.getBarcodeFormat().getName()); // Prints the scan format (qrcode, pdf417 etc.)
// If you would like to resume scanning, call this method below:
mScannerView.resumeCameraPreview(this);
}
}

Rebuilding ZBar Libraries
mkdir some_work_dir
cd work_dir
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz
tar zxvf libiconv-1.14.tar.gz
Patch the localcharset.c file: vim libiconv-1.14/libcharset/lib/localcharset.c
On line 48, add the following line of code:
#undef HAVE_LANGINFO_CODESET
Save the file and continue with steps below:
cd libiconv-1.14
./configure
cd ..
hg clone http://hg.code.sf.net/p/zbar/code zbar-code
cd zbar-code/android
android update project -p . -t 'android-19'
Open jni/Android.mk file and add fPIC flag to LOCAL_C_FLAGS. Open jni/Application.mk file and specify APP_ABI targets as needed.
ant -Dndk.dir=$NDK_HOME -Diconv.src=some_work_dir/libiconv-1.14 zbar-clean zbar-all
Upon completion you can grab the .so and .jar files from the libs folder
