An Android emulator is an Android Virtual Device(AVD) that emulates the Android environment for other devices to run the Android operating system. It is generally used for testing, bug-finding, running various apps on a virtually controlled system on devices other than actual Android phones.

I am in the process of building some mobile apps for one of my clients, and while I'm pretty familiar with running the iPhone simulator and, I'm pretty new to the Android development tools at this point. So I thought I would give a quick and easy guide for folks to follow, that might be interested in getting started with Android Development and running the Android Emulator. I should mention that there is also an Eclipse Plugin for Android Development as well that you can use instead. Also, I'm using a Mac, but I think the steps should be pretty close if you are running Windows or Linux. Step 1 - Download the Android SDK the Android SDK, and unzip it somewhere. I placed the android-sdk-mac86 folder in my /Applications/ folder, but you can put it wherever you want. Step 2 - Optional Add to System Path Since we are using the command line you might find it useful to add the android-sdk- platform/tools folder to your system path so you can run the android commands from any folder.
If your interested in doing that, Google provides instructions. Step 3 - Install Android Platforms At this point, I tried running the emulator command, but the SDK doesn't contain any Android Platforms, the Android platform is essentially Android OS, you need to install at least one version (eg 1.6, 2.1, 2.2, etc) to run the emulator. To install platforms run the android command located in the tools folder of the SDK (use Terminal.app on a Mac, or the Command Prompt on Windows, Linux folks you know what to do:). This will pop up a window. Select Available Packages, pick some platform versions and install. Step 4 - Create a Virtual Device Still in the android tool, click on Virtual Devices on the left, and then click New. Here's an example of the settings for the new device.
I am getting the following message:- Starting emulator for AVD '40And4' Failed to create Context 0x3005 emulator: WARNING: Could not initialize OpenglES emulation, using software renderer.
