Off course it shows only one checkbox for API level 8, because may be you have downloaded only the SDK Platform Android 2.2, API 8 And API level 3 means you want to run your application on Android 1.5. So you also have to download SDK Platform Android 1.5, API 3

To download this open the Android SDK and AVD Manager and click on Available Packages. Here you can find SDK Platform Android 1.5, API 3 inside the Android Repository and after downloading this you have to create a new Android Virtual Device by selecting Target as Android 1.5 API Level 3. After that you will be able to change API Level 8 to 3

First: Install the desidered apis in your AVD-Manager.

Second: You have also to change the line <uses-sdk android:minSdkVersion="4" /> in your AndroidManifest.xml

Start your SDK and AVD manager, choose "Installed Packages" and delete the unnessecary APIs.
