public interface GetDataStreamCallback
GetDataStreamCallback
is used to run code after a ParseFile
fetches its data on
a background thread.
The easiest way to use a GetDataStreamCallback
is through an anonymous inner class.
Override the done
function to specify what the callback should do after the fetch is
complete. The done
function will be run in the UI thread, while the fetch happens in a
background thread. This ensures that the UI does not freeze while the fetch happens.
file.getDataStreamInBackground(new GetDataStreamCallback() { public void done(InputSteam input, ParseException e) { // ... } });
