"Good" versus "not good" is a binary statement. In reality, it is more a continuum of increasing "not good" as you increase the number of ListViews, the number of rows in those ListViews, and the number of widgets per row (TextViews, layouts, etc.) that you wind up holding onto to achieve your desired effects. The "fatter" your activity becomes, the more likely it is that it will be "not good" in the eyes of users, because: -- It crashes due to out of memory errors, perhaps on lower-end handsets that come with less RAM for applications -- It kicks too many other applications out of memory when it runs -- It generates so much garbage that the garbage collector slows down whatever application they run next (e.g., a game or video that cannot keep up the frame rate) -- It winds up being killed off forcibly, rather than gracefully shut down and saving its state, because it uses up too much memory and Android needs that memory quickly to handle some incoming phone call or text message or something -- And so on Whether your app meets any of those criteria is impossible to say based on a set of emails -- only you and your users will be able to tell. So, while I am convinced that several thin, cheap activities are better than one fat, expensive activity that performs all the same functions, that is just a rule of thumb. Only you and your users have the application and can determine if, indeed, you are using more memory than is wise. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Need Android talent?
