Hi! I would like for our platform to be more strict about apps doing network operations in the main thread. This is something that would largely help our apps stay smooth and snappy. As an example Android does not allow developers to do network requests on the UI thread, any such attempt results in a NetworkOnMainThreadException. This definitely results in a more crisp experience.
Perhaps we could provide some sophisticated API for the developers so that they don't really have to handle threading directly, atleast for simpler operations. (If there already is please enlighten me). Android provides AsyncTask[1] to do exactly that. So basically it provides a few override methods doInBackground(): any code that runs inside this method is executed in a worker thread. onPreExecute(): here you may show some nice spinner/dialog to tell the user something is being downlaoded (main thread) onPostExecute(): this is called after the background operation completes. (main thread) iOS has Grand Central Dispatch[2] for similar reasons, though I don't really know how that works so can't detail that out.
