Google’s announcement of Android 4.1 Jelly Bean touched on a ton of new features and improvements to the how the platform operates. Now that the SDK is available for developers, we fired-up the Android emulator to get a hands-on look for ourselves at some of those changes.
Have fun 
To get the emulator working for yourself:
1. Download the Android SDK from developer.android.com and install all Packages, especially API 16
2. In the SDK folder, open AVD Manager
3. Click New
4. Type a name, select Android 4.1 as the target, chose your screen resolutio
5. Click create, then click Start

You must hate yourself then. No phone in 2 mhtnos is going to take 25% of the mobile market. The iPhone sure as hell didn’t do that. It has taken years. Now what you missed or just didn’t want to see when you looked at those numbers is that Android will ship on as many units as the iPhone will ship this year. And its expected to overtake the iPhone in sales within the next year or so. Next time check all the numbers before you talk.
