Android Studio vs Xamarin

Android Studio
Android Studio is a new Android development environment based on IntelliJ IDEA. It provides new features and improvements over Eclipse ADT and will be the official Android IDE once it's ready.
We created Xamarin because we knew there had to be a better way – a better way to design apps, to develop apps, to integrate apps, to test apps and more. We’re developers, so we know what developers want from mobile app development software: a modern programming language, code sharing across all platforms, prebuilt backend connectors and no-compromise native user interfaces.
Comparing Android Studio vs Xamarin is like comparing apples to oranges. Because your business is unique and nobody except you can decide, which is better for your company. But we can add some fun to your research and suggest some new comparison parameters.

Ok, now let's compare the UI. Looks like Xamarin has more user-friendly interface than Android Studio because it's bigger. At least on our screenshots

To compare the popularity of the solutions we counted how many alternatives people search for each of them on the Internet. And it turns out that Xamarin is more popular than Android Studio

Now let's look at the recent activities of our competitors:

- Xamarin now lets run and test iOS apps directly from Windows (in 2017)
- Microsoft's development platform Xamarin integrates with Visual Studio (in 2016)
- Microsoft acquired mobile development service Xamarin (in 2016)
- Android Studio 2.0 features Instant Run (in 2015)
- Xamarin improves its mobile app development platform (in 2015)

Looks like Xamarin was recently more active than Android Studio (at least in our news).
