Xamarin Android Push Notifications using Google Cloud Messaging (GCM) and ASP.Net

.Net ASP.Net Xamarin

This post is about implementing Push Notifications in Xamarin Android using Google Cloud Messaging (GCM). Google Cloud Messaging for Android (GCM) is a free service that helps developers send data from servers to their Android applications on Android devices, and upstream messages from the user’s device back to the cloud. The GCM service handles all aspects of queueing of messages and delivery to the target Android application running on the target device. A GCM implementation includes a Google-provided connection server, a 3rd-party app server that interacts with the connection server, and a GCM-enabled client app running on an Android device.

.Net .Net 4.0 Visual Studio

Today I faced an issue while compiling the project with VS 2010. First I thought it was due to invalid snk file. But I confirmed it, that was not the problem. Later I found it was a permission issue. The solution is very simple, to resolve this error; open the following folder - “C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys”, and give your user (whatever account you use to log onto your computer and work on Visual Studio) full control. You can do it by Right click on the MachineKeys folder and select properties, and in the security tab, make sure the current user have full control.

Time ago function for C#

.Net .Net 4.0 ASP.Net ASP.Net MVC Windows Forms

Here is a small C# snippet which will return a date time value in a readable way as facebook,twitter, stackoverflow and most of the forum sites, like 1 day ago,1 min ago etc. If you’re building a website, then the jQuery plugin Timeago is a pretty sweet way to do it (as long as you can stand webpages that auto update text). I have wrapped it in an extension method.

This is post is about another hybrid application scenario. I had to implement this in one of our projects, the problem was like this, unlike other hybrid applications, this project had a native login screen, which will authenticate the user against a REST API service and once the authentication is successful, service will set an authentication cookie. And once authentication is completed, application will start a new activity, which will load the web application. If cookie is not present, the web application will show the Forms authentication screen.

How to convert JSON to XML and vice versa in C#

Json.NET supports converting JSON to XML and vice versa using the XmlNodeConverter. The JsonConvert has two helper methods for converting between JSON and XML. The first is SerializeXmlNode(). This method takes an XmlNode and serializes it to JSON text.
