copied!<p>Register a <code>BroadcastReceiver</code> in the fragments you have and in its <code>onReceive</code> call <code>refresh</code> - this method is supposed to update the UI depending what you have inside. For making your code easy to use, have a base <code>Fragment</code> class and do the registering/unregistering there along with an abstract <code>refresh</code> method that will be implemented by children fragments. Something like:</p> <pre><code>public abstract class BaseRefreshableFragment extends Fragment { private BroadcastReceiver refreshReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { if ("package_name.REFRESH_ACTION".equals(intent)) { refresh(); } } }; public void onViewCreated(View view, Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); IntentFilter filter = new IntentFilter("package_name.REFRESH_ACTION"); LocalBroadcastManager.getInstance(getActivity()).registerReceiver(refreshReceiver, filter); } @Override public void onDestroyView() { LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(refreshReceiver); super.onDestroyView(); } protected abstract void refresh(); } </code></pre> <p>In your <code>Service</code>, when your work is done, broadcast an intent with above action. So if there are fragments to show updated data, their receiver will be notified and that will call <code>refresh</code> <em>ON EACH FRAGMENT</em>. Something like from your service:</p> <pre><code>Intent intent = new Intent("package_name.REFRESH_ACTION"); LocalBroadcastManager.getInstance(MySyncService.this).sendBroadcast(intent); </code></pre> <p>The advantage is that you don't need to care when the fragment is shown or not since the receiver is there for the life-time of your fragment's view.</p>
