Classes
The following classes are required for the SDK.
| Classes | Description |
|---|---|
| DatalogicDeviceManager | Class manages the attached Datalogic Scanner. |
| DatalogicDevice | Class represents for Datalogic Scanner. It contains the Datalogic Scanner details and all functions to interact with Datalogic Scanner. |
| UsbScanData( val rawData: ByteArray, val barcodeData: String, val barcodeType: String ) | Data class passed by onScan to retrieve scanned data from the USB Scanner. |
| ScaleData( val status: String, val weight: String, val unit: ScaleUnit ) | Data class passed by onScale to retrieve scale data from the USB Scanner. |
DatalogicDeviceManager
Management class for the Datalogic Scanner device. Used to detect USB Scanner Devices and register scanner events. USB permission is required for communicate with USB devices.
| Public Methods | Description |
|---|---|
| ArrayList < DatalogicDevice > detectDevice(context: Context) | get the connected devices list and prepare the DatalogicDevice based on the product Id. Return the connected device list of ArrayList < DatalogicDevice >. |
| Int registerUsbListener(listener: UsbListener) | Register a listener for USB Events to notify when the USB Scanner connected or disconnected. |
| Int unregisterUsbListener(listener: UsbListener) | Unregister listener for USB Events. |
| Int registerStatusListener(listener: StatusListener) | Register listener for device Status Changes. |
| Int unregisterStatusListener(listener: StatusListener) | Unregistered listeners for Status event. |
DatalogicDevice
Class represents for Datalogic Scanner. It contains the Datalogic Scanner details and all functions to interact with Datalogic Scanner.
| Public Methods | Description |
|---|---|
| Int openDevice(context: Context) | This method opens a connection to the specified DatalogicDevice, allowing for communication with the device’s endpoints. Return 0 if the interface was successfully opened, -1 otherwise. |
| Int closeDevice() | Close the DatalogicDevice. |
| Int registerUsbScanListener(listener: UsbScanListener) | Register listener for USB scan event to be notified when the Scanner scans the barcodes. |
| Int unregisterUsbScanListener(listener: UsbScanListener) | Unregister listeners for Scan event. |
| Int registerUsbDioListener(listener: UsbDioListener) | Register listener for Usb dio event to be notified when the Dio Commands get failed. |
| Int unregisterUsbDioListener(listener: UsbDioListener) | Unregistered listeners for dio error event. |
| String dioCommand (device: UsbDeviceDescriptor, commandType: DIOCmdValue,cmd: String, context: Context) | Function to execute the DIO Commands and return status value (Command type and valid command value should be correct for output). |
| HashMap < ConfigurationFeature, String > readConfig(device: UsbDeviceDescriptor, context: Context) | Function to execute the read config Commands. |
| HashMap < ConfigurationFeature, String > writeConfig(type: String, data: HashMap < ConfigurationFeature, String > ) | Function to execute the write config Commands. |
| ByteArray imageCaptureAuto(currentBrightness, currentContrast) | Function to capture image. The parameter currentBrightness and currentContrast only is applied for HHS device. |
| startScale() | Start to receive scale data. |
| stopScale() | Stop to receive scale data. |
UsbScanData
Data class containing the data of a scanned code. Can retrieve barcode data either as a String or an array if bytes.
| Public Properties | Description |
|---|---|
| byte[] rawData | Get the barcode data as an array of bytes. |
| String barcodeData | Get the barcode data as a String. |
| String barcodeType | Get the barcode ID as a String. |
