================================
Cross-platform BarcodeScanner for Cordova / PhoneGap.
Follows the Cordova Plugin spec, so that it works with Plugman.
This requires phonegap 5.0+ ( current stable v3.0.0 )
phonegap plugin add phonegap-plugin-barcodescanner
Older versions of phonegap can still install via the deprecated id ( stale v2.0.1 )
phonegap plugin add com.phonegap.plugins.barcodescanner
It is also possible to install via repo url directly ( unstable )
phonegap plugin add https://github.com/phonegap/phonegap-plugin-barcodescanner.git
Note: the Android source for this project includes an Android Library Project. plugman currently doesn't support Library Project refs, so its been prebuilt as a jar library. Any updates to the Library Project should be committed with an updated jar.
Note: Windows 10 applications can not be build for AnyCPU architecture, which is default for Windows platform. If you want to build/run Windows 10 app, you should specify target architecture explicitly, for example (Cordova CLI):
cordova run windows -- --archs=x86
Note: Since iOS 10 it's mandatory to add a NSCameraUsageDescription in the info.plist.
NSCameraUsageDescription describes the reason that the app accesses the user’s camera.
When the system prompts the user to allow access, this string is displayed as part of the dialog box.
To add this entry you can pass the following variable on plugin install.
cordova plugin add phonegap-plugin-barcodescanner --variable CAMERA_USAGE_DESCRIPTION="To scan barcodes"
If you are using Phonegap Build you can add this to your config.xml
<gap:config-file platform="ios" parent="NSCameraUsageDescription" overwrite="true">
<string>We are using the Camera for something..</string>
</gap:config-file>
If you're using PhoneGap Build please make sure you specify gradle as your Android build tool in config.xml: <preference name="android-build-tool" value="gradle" />.
The plugin creates the object cordova.plugins.barcodeScanner with the method scan(success, fail).
The following barcode types are currently supported:
Not by default, but supported if you pass in the "formats" option:
success and fail are callback functions. Success is passed an object with data, type and cancelled properties. Data is the text representation of the barcode data, type is the type of barcode detected and cancelled is whether or not the user cancelled the scan.
A full example could be:
cordova.plugins.barcodeScanner.scan(
function (result) {
alert("We got a barcode\n" +
"Result: " + result.text + "\n" +
"Format: " + result.format + "\n" +
"Cancelled: " + result.cancelled);
},
function (error) {
alert("Scanning failed: " + error);
},
{
preferFrontCamera : true, // iOS and Android
showFlipCameraButton : true, // iOS and Android
showTorchButton : true, // iOS and Android
torchOn: true, // Android, launch with the torch switched on (if available)
prompt : "Place a barcode inside the scan area", // Android
resultDisplayDuration: 500, // Android, display scanned text for X ms. 0 suppresses it entirely, default 1500
formats : "QR_CODE,PDF_417", // default: all but PDF_417 and RSS_EXPANDED
orientation : "landscape", // Android only (portrait|landscape), default unset so it rotates with the device
disableAnimations : true, // iOS
disableSuccessBeep: false // iOS
}
);
The plugin creates the object cordova.plugins.barcodeScanner with the method encode(type, data, success, fail).
Supported encoding types:
A full example could be:
cordova.plugins.barcodeScanner.encode(cordova.plugins.barcodeScanner.Encode.TEXT_TYPE, "http://www.nytimes.com", function(success) {
alert("encode success: " + success);
}, function(fail) {
alert("encoding failed: " + fail);
}
);
Windows implementation currently doesn't support encode functionality.
On Windows 10 desktop ensure that you have Windows Media Player and Media Feature pack installed.
Windows Phone 8 implementation currently doesn't support encode functionality.
BlackBerry 10 implementation currently doesn't support encode functionality. Cancelling a scan on BlackBerry 10 is done by touching the screen.
So many -- check out the original iOS, Android and BlackBerry 10 repos.
