That's an indication you're doing it wrong. Anything time-consuming should not be done in the GUI thread, but in an AsyncTask in the background. You can display a message like "fetching data from server" or something like that while the network call hasn't finished, but all Activity lifecycle methods should return quickly. (They *must* return quickly, actually, because Android will terminate activities that don't respond within a certain timeframe - which can be as short as 10 seconds or so.)
 
It is sorta covered in the JavaRanch Style Guide.
