We are using ZXing (pronounced "zebra crossing") image processing libraries to scan QR Code using Android device
. The solution involves easy steps to integrate Zxing libraries with Android to direct auto scan of QR Code. We are using Android environment for development that Eclipse Java IDE.
Setp1: Acquire Zxing libray (Zxing 1.7 release bundle) from here (http://code.google.com/p/zxing/downloads/list)
Step2: Extract the zip bundle.
Step3: Create a new Android sample Project in Eclipse for QR Code Auto Scanner Test and set target to Android 2.2 SDK version.
Step4: Locate Android folder from the extracted bundle and pick CaptureActivity.java source file.
Step5: Also locate Core folder and import the source into the above sample project.
Step6: Change the package name of above CaptureActivity.java file to match the above sample project package structure.
Step7: Design a sample page with a SCAN button to add to the above sample project.
Step8: Add navigation to SCAN button click event as shown below
Intent scanner = new Intent(QRCodeAutoScannerTest.this, CaptureActivity.class); startActivity(scanner);
Step9: Change the existing manifest file to add the below filters
Step10: Also change manifest file to add the below permissions
Step11: Compile the project.
Step12: Deploy into 2.2 Android devices to test the App.
