I have seen many dashboard implementations of quite popular android apps. So I don't think Dashboard pattern is against the Android 4 Design Guidelines.
However dashboard performances can be an issue, if you are making lot processing to produce dashboard UI elements. This could lead to exceeding approved memory limit.
