Initialize
Initialize the Docutain SDK as described here.
Camera Permission
Declare the following permission in your AndroidManifest.xml
<uses-permission android:name="android.permission.CAMERA"/>
<uses-feature android:name="android.hardware.camera"/>
Runtime permission for camera is handled automatically by the Docutain SDK.
Start the barcode scanner
To start the barcode scan process you only have to call scanBarcode with valid barcodeScannerConfiguration and wait for it to return.
const scanConfig = {
codeFormats: ['CODE_128', 'CODE_39', 'CODE_93', 'EAN_13', 'EAN_8', 'ITF', 'UPC_A', 'UPC_E', 'CODABAR'],
};
try
{
result = await DocutainSDKBarcode.scanBarcode(scanConfig);
}
catch(ex)
{
errorMsg('scanBarcode', ex);
return
}
Valid BarcodeScannerConfiguration
is required to launch the barcode scanner. It provides the possibility to change some behaviours to adopt it to your needs.
const scanConfig = {
vibrateOnSuccess: false, //defaults to true
beepOnSuccess: true, //defaults to false
codeFormats: ['CODE_39'], //defaults to all supported barcode formats
//more configs available
If you need to scan only specific barcode formats, you can improve the barcode scan performance by defining the barcode formats by setting scanConfig.codeFormats
like in the example above.
All parameters in BarcodeScannerConfiguration
are optional.
