Howto Install and Run the Android Emulator

Updated: May 27, 2020

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 building iPhone apps, 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

Download the Android SDK, and unzip it somewhere. I placed the android-sdk-mac_86 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.

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 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:

android virtual device manager, create avd file

Once you create the avd file, it should show up in the listing of Android Virtual Devices:

android virtual devices listing

Step 5 - Run the emulator

Now select the virtual device you just created and click Start on the right, and the emulator should start running:

@AAP The Android site does provide useful and very detailed documentation. I am not trying to replace their documentation here, rather I'm trying to illustrate how to get up and running quickly.

When I first installed Android SDK on Windows it refused to work and no meaningful error message was displayed. Resorting to tools like SysInternals ProcMon I was able to figure out Android SDK depended on Java. I had Java JRE, but its path was not set on the PATH environment variable.

So if you happen to see similar behaviour when you first install Android SDK, check Java JRE/JDK is installed and the directory it was installed in is included on the PATH environment variable.

After creating virtual device when i click run i'm getting the following error
"invalid command-line parameter: Files.
Hint: use '@foo' to launch a virtual device named 'foo'.
please use -help for more information"

@invalid command-line parameter error:
Either use a file-name without spaces, or alternatively, use the older format for folder - the one which uses 8 chars, so replace c:\program files\android-sdk with c:\progr~1\android-sdk
