android fragment internal notes


Android fragment is really awesome. somehow i kept on forgetting how to implement it after a few weeks down the road. :)

Full source code for this is available in github.

Simple Fragment 

To create a basic fragment on your activity that looks like this :-


Say this is a Fragment A and when you swipe, it goes to Fragment 2.

To create this simple layout, you need

a) ViewPager on your layout.

OpenCover code coverage for .Net Core

I know there are many post out there getting code coverage for .dotnetcore. I'm using opencover to address this needs.

In case, you do no want to use opencover and wanted to stick with vs2015 code coverage, you can try to copy Microsoft.VisualStudio.CodeCoverage.Shim.dll from C:\Program Files (x86)\Microsoft Visual Studio 14.0\Team Tools\Dynamic Code Coverage Tools\coreclr\ and drop it into your project "bin\Debug\netcoreapp1.0" folder.  Please note : you need to be on VS2015 Enterprise to do this.

C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5\System.Data.DataSetExtensions.dll

Try to do a dummy Build and you should be able to get it.
