About EMDK For Xamarin

EMDK For Xamarin 5.0

Overview

EMDK for Xamarin is an IDE extension that provides developers with a comprehensive set of tools to easily create powerful line-of-business applications for Zebra Android devices using C# skills and tools. EMDK for Xamarin includes class libraries, sample applications and source code, and all associated documentation for building applications that take full advantage of the power of Zebra devices.

EMDK for Xamarin inserts the Zebra-exclusive Profile Manager technology within the IDE, providing a GUI-based development tool for configuring Zebra devices. This allows developers to write fewer lines of code, produce fewer errors, and reduce overall development time and effort.

    • decodeScreenTranslucencyLevel sets the percentage of translucency of the decode screen notification overlay.
  • Added a ScannerConfig.MultiBarcodeParams parameter:
