Develop an android app with Visual Studio 2010 and C#?
<p>I've seen several versions of this questions, but none of them seem to give me the answer I'm looking for.</p>

<p>I'm a software engineer and I do all my development with VS2010, C#, and Sql Server as back-end. An opportunity came up where the client wants to develop a simple application to run in a tablet. We initially agreed on an android tablet (the 7" Amazon Fire) since I still haven't found a $50 Windows tablet, and this software will be deployed in many units.</p>

<p>It's an uphill battle since this is the first time I'd create an app designed for an android tablet, and I'd like to try working on the project only if I can use the tools that I currently use.</p>

<p>So my question is: can one use VS2010/C# to develop an android app? Or would I need to learn a new language, download 3rd-party software, etc?</p>

<p>I can download VS2012 or a newer version of the IDE, but my only requirement is that I can use what I already know, or possibly, if I can purchase a time-tested plug-in to Visual Studio.</p>

<p>I'm also open to HTML5, only if I can develop in VS2010. The app can run in a browser.</p>

<p>Thanks.</p>
