Ok, so now that you downloaded and installed the Android SDK and created your first AVD we need to move on to the Development environment.
Wait… you didn’t install the SDK??? Start here – Linky
So you will need to download and install Eclipse… What is eclipse? you can review their WIKI – Linky and here is a simple description on what they are…
Eclipse is an open source community, whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the lifecycle. The Eclipse Foundation is a not-for-profit, member supported corporation that hosts the Eclipse projects and helps cultivate both an open source community and an ecosystem of complementary products and services.

Step 2 – Download and install Eclipse environment
Open Eclipse Website – Linky
Now download Eclipse IDE for Java Developers, based on the OS you have
eclipse

Now on the download page either download via HTTP or Torrent, more links are on the page (I wanted a smaller screen shot)
eclipsedownload

After the download is completed extract the content of the file to a folder you want to work in.
In my case it was C:\Android\Eclipse
And run the eclipse.exe main application from where you extracted it to
eclipse1

Hit Continue Reading to move on…

Now a workspace launcher screen will show, the path is of where you are going to store and work on your android projects.
I like to keep it simple so C:\Android\Projects is my workspace
eclipse2

Eclipse will load with a welcome screen please close it
eclipse3

Now you see your main clean Development environment with Eclipse, but… you still can’t develop anything for android, we need to update a few things and tie Eclipse to our Android SDK
eclipse4

Hit Help –> Hit Install New Software… and wait for a new screen to show
eclipse5

Now on this screen you will need to specify google’s download path
Copy this to the “Work With” box –> https://dl-ssl.google.com/android/eclipse/ then hit the add button
eclipse6

Next screen will add this source to your Eclipse, give it a name and hit OK
eclipse7

Now new available packages will appear in the main area, hit Select All and then hit Next
eclipse8

Now when all the files have completed their download and have been installed you will need to setup your Android SDK
In Eclipse hit Window –> Preferences
Select Android
Select Browse and point to your SDK folder
Hit Apply
You will have all the available versions to work with show up, right now we are up to 2.3
eclipse9

Now just to make sure everything is setup correctly we will simply try to start a new Android Project
Hit File
Hit New
Hit Other
eclipse10

And now select Android from the list and Android Project
eclipse11

That’s it you are done with the Development environment.

What’s next time?
Our first simple application and Android Project Structure.
