There was no need to change any of the code writing paths and points into the Realm because they just work the same way.Security is now in the driving seat of any software development process. The important thing about the changes to LiteDrawer above are what we didn’t change. If you edit its color, they all redraw with that path in a different color. If you delete a DrawPath, it will vanish from all the devices. Points = `Īs a fun experiment, you can directly open the SharedScribbles Realm on the server with the Realm Browser (running on MacOS). Open the Main.Storyboard with the visual editor.Now clean up each project to remove the template UI and add a SkiaCanvas.We will use a Shared project for the common code. Start with a new Single View project for iOS and Android.That keeps things a little simpler so you can focus on the drawing code and particularly sharing drawing with RMP. There is not yet a simple way to capture complex touch events, within Xamarin Forms, so this tutorial code uses native UI projects. For more background on SkiaSharp, see the Xamarin blog post on SkiaSharp. Our tutorial starts with some hardcoded drawing to prove your SkiaSharp installation works, then moves on to how to draw in response to touches, and concludes by integrating Realm. Sudo systemctl enable realm-object-server Sudo apt-get install realm-object-server-developer # Update repositories (may not be necessary on a new server) # Download the Realm Object Server repository from PackageCloud Now we use the steps from Install the Realm Object Server below to install and start the Realm Object Server.Use SSH to connect to your server so you have a terminal session.Note that you do not need to create a new Network Security Group as one has already been created with your server – you will see it contains a definition for port 22 which is why you can use SSH to connect. Follow the “ Opening ports to a VM in Azure using the Azure portal” guide and allow through port 9080. Follow the “ Create a Linux VM on Azure using the Portal” documentation to create an instance of Ubuntu Server 16.04 LTS.We will use the Ubuntu version of the server. Setting Up a Realm Object Server on Azureīefore we get into the app development, here’s a quick guide to setting up a Development server on Azure, mostly following the standard Microsoft guides. It assumes a reasonable familiarity with Xamarin Studio to build a Xamarin app. This tutorial shows how to build a simple freehand drawing app using SkiaSharp and then, with the aid of the Realm Mobile Platform (RMP), make it a shared drawing app. We wanted a Xamarin app to match that would also show how easily code can be shared across Android and iOS. The challenge had already been laid down by the Realm Cocoa Team showing how cool a shared drawing app can be with Realm. Xamarin introduced Skia Sharp in February 2016 so it was a natural choice when we needed a vector drawing library for our RealmDraw sample. With these tools, we wanted to show you how quickly you could make a collaborative app that syncs in realtime, while maybe having a little fun along the way, so we’ll be rewriting the RealmDraw app in Xamarin. Today, Realm is announcing a couple of really neat things for Xamarin users, including the 1.0 release of the Realm Mobile Database, and support for Xamarin on the Realm Mobile Platform. When not sweating over code he can be found sweating at kung fu and online at andydent.name. This is a special guest post from the Realm team, written by Andy Dent.Īndy Dent is a C# developer at Realm, working virtually in Copenhagen from the sunny state of Western Australia.
