Both are provided by Zebra and it is recommended to use the official library.
ZEBRA SCANNER ENTER AFTER SCAN ANDROID
There is both a native android and a C# Binding Xamarin Android library for the EMDK library. Go ahead and create that exact file in your project if you have not done so yet. Earlier we created our specification as a C# interface. Now that the app is built and we have the necessary controls we can start building our Barcode Scanning EMDK Wrapper implementation. Make sure to run your app at this point and verify that everything is rendering correctly. Set our view from the "main" layout resource Protected override void OnCreate(Bundle savedInstanceState) Public class MainActivity : AppCompatActivity, View.IOnClickListener
ZEBRA SCANNER ENTER AFTER SCAN CODE
I omited Xamarin Essentials from this example, if you create a new Xamarin Android project it ships with Xamarin Essentials out of the box so your code may look slightly different than this. With any good code wrapper it will be best to define our API prior to implementation, this will give us a good foundation on what we are building and how the client will be using it.Īt this point our MainActivity won't have many changes to it, here is our current MainActivity code. In our example we are going to isolate the scanning code from any Android Activity. The goal is to get hardware access to the barcode sanner to execute custom code when the Android App receives data from the hardware. There are a lot of moving parts to keep straight and it is not as easy as plug and play.
With great power comes great responsibility, which holds true with the EMDK library. Zebra provides 2 libraries for handling barcode scanning DataWedge and EMDK there are reasons to use both and Zebra’s official recommendation as of today is to use the DataWedge I am personally a fan of the EMDK library as it gives your app 100% custom control to everything including your configuration pages. This really isn’t ideal when the app requires scanning multiple barcodes in sequence. If you have ever built a barcode scanning app that uses a camera there is a lot of switching back and forth between the camera and the page. This allows developers to create rich barcode scanning capable apps without using the camera. The Zebra TC70x is a mobile touch computer or android device with built-in hardware barcode scanning.
