Android: Starting new Activity with custom object through Intent

public class TaskActivity extends Activity
{

@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.task);
Intent i = getIntent();
Task task = (Task) i.getSerializableExtra("task");

configureButtons();
}

}
