It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.
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.
