Recently I downloaded the Android SDK, but I ended up installing SDK-Platform for API-version 10 (Android 2.3.3), since that is the version I wanted to work with initially. However now I also need to work with Android 4.0.3, but SDK Manager continually fails to install the SDK-Platform for API-version 15, and thus doesn't install the corresponding system images either.
So I'm wondering, as to what is the right way to work with Android ICE, Jellybean (in future) and Gingerbread, on the emulators?
