public abstract class SendCallback extends AVCallback<java.lang.Void>
A SendCallback is used to run code after sending a AVPush in a background thread.
The easiest way to use a SendCallback is through an anonymous inner class. Override the done function to specify what the callback should do after the send is complete. The done function will be run in the UI thread, while the send happens in a background thread. This ensures that the UI does not freeze while the send happens.
For example, this sample code sends the message "Hello world" on the "hello" channel and logs whether the send succeeded.
AVPush push = new AVPush(); push.setChannel("hello"); push.setMessage("Hello world!"); push.sendInBackground(new SendCallback() { public void done(AVException e) { if (e == null) { Log.d("push", "success!"); } else { Log.d("push", "failure"); } } });
