I used a few days, setting up android sdk and eclipse so I
could make my own android widgets.
So here is a short toturial on how to do it nice and clean.
1. Get the android SDK installer.
http://developer.android.com/sdk/index.html
When you have downloaded it, unzip it to the place where you want
to use it from, like c\:program files\"android sdk".
Now you run the "SDK Setup.exe".

If you get a error when its trying to get Available Packages, go
to settings and check the "Force https:// to be fetched using
http://".
2. Get Eclipse Classic's from http://www.eclipse.org/downloads/
When you have downloaded it, unzip it to the place where you
want to use it from, like c\:program files\"eclipse".
Run eclipse.exe, first thing set up your workspace, the place
where it stores your projects.
When that is done, got to help and select "Install New
Software..."
"Work with:" add : https://dl-ssl.google.com/android/eclipse/
Install the 2 options that it provides.

Next go to "Window" and select "Preferences", and "Android".

Set the SDK Location: to the path where you installed the
android SDK.
like : C:\Program Files\android sdk\
Click Apply, and now it will start to set up the Android
sdk's.
Now it sould all be ready.... enjoy
any questions, shoot. :o)
