On the developer website there are these instructions:
Configure the ADT Plugin Once Eclipse restarts, you must specify the location of your Android SDK directory:
- In the "Welcome to Android Development" window that appears, select Use existing SDKs.
- Browse and select the location of the Android SDK directory you recently downloaded and unpacked.
- Click Next.
Your Eclipse IDE is now set up to develop Android apps, but you need to add the latest SDK platform tools and an Android platform to your environment. To get these packages for your SDK, continue to Adding Platforms and Packages.
My problem is that I can't do what is written in number 1 because I don't have that option on the welcome to android... by that option I mean that I don't have the option to select "use existing SDKs"
