DWDemo provides barcode scanning capabilities, demonstrating how data is acquired by an application using the DataWedge intent output. It is provided by default on all Zebra Android devices.
Figure 1: DWDemo in Apps screen
A DataWedge Profile called "DWDemo" is pre-configured in DataWedge and associated with the demo app. The DWDemo Profile must be enabled and can be modified as needed for testing or demo purposes. Once the demo Profile is enabled, tap the app's yellow Scan button or press the device hardware trigger to initiate a barcode scan. Decoded data is displayed on the app screen.
The DWDemo app supports scanning with the imager, camera, Bluetooth device or a magstripe reader (MSR), if one is connected.
