public interface GetDataCallback
GetDataCallback
is used to run code after a ParseFile
fetches its data on a
background thread.
The easiest way to use a GetDataCallback
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.getDataInBackground(new GetDataCallback() { public void done(byte[] data, ParseException e) { // ... } });
