Class GetDataCallback

java.lang.Object

com.avos.avoscloud.AVCallback<byte[]>

com.avos.avoscloud.GetDataCallback

public abstract class GetDataCallback
extends AVCallback<byte[]>

A GetDataCallback is used to run code after a AVFile 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, AVException e) {
     // ...
   }
 });
