2 questions about .apk packaging

I packed a small level in .apk. By the log, I see that he packed a bunch of everything downloaded from the marketplace, which are not used. Is it possible to pack only what is located on the level, and not the entire project?

And how can I keep track of optimization indicators so as not to overdo it with visuals and lags on the phone?
