Animation Freeze while requesting server

refresh_layout.setOnRefreshListener(new PullRefreshLayout.OnRefreshListener() {

```
@Override
public void onRefresh() {
// TODO Auto-generated method stub

refresh_layout.post(new Runnable() {

@Override
public void run() {
// TODO Auto-generated method stub
refresh_layout.setRefreshing(true);
// requesting to webservice
}
});
}
});
```

Start from the OnRefreshListener.onRefresh callback and the refresh_layout.setRefreshing(true) call shown in the report. Reproduce the behavior while the webservice request runs, then trace how the refresh animation and request interact. Done means the refresh animation does not freeze during the server request.
