MainActivity.OnResume - Stop "OnResume" interval.
#Xamarin studio android android
Then for timing a Xamarin.Forms Android app, I call Start/Stop methods in various places: So my approach is to use a static class such as the following, allowing you to name different time intervals across your app: To make things even more complex, timing the time it takes a page to appear in Xamarin.Forms requires changes across different classes: your activity/controller, your XF page, and potentially custom renderers. This would be timing your app at more of an "integration test" level, and I've not found a library that does this yet. Unfortunately timing performance within a Xamarin.Forms app (or even a classic Xamarin app) is not quite as easy. If you want to time performance in your shared C# code, this is the way to go.

If you are trying to benchmark plain C# code at a lower level, you can luckily rely on a few existing benchmarking libraries:īoth of these libraries will run on your desktop machine to time C# code at what you can think of as at a "unit test" level. Unforunately I haven't found alot of guidance out there on timing Xamarin.Forms applications, but I'll share the approach I've been using. These are some great resources I would start with, now let's dive into some of my discoveries.īefore doing any performance-related work, you need to make sure you have a valid understanding of the current performance in your app. Read the official docs on Xamarin.Forms perf.I would start by making sure you are already doing what is currently recommended by others. There is already quite a bit of content out there on Xamarin.Forms performance. However, as all performance-related work goes, it isn't that easy.Īs a starting point, I thought I would share some easy tricks you can apply to your apps right now. It turns out that one of our most common Xamarin project is developed with Xamarin.Forms in Visual Studio on Windows.
One of the tasks that has always been in the back of my mind on the Xamarin.Android team is to make some improvements to help Xamarin.Forms apps. It's been a while since my last post, I've been on parental leave-a great feature of working for Microsoft.
