Apps Widget not clickable

[pep987]

Hi, I am new to programming android, and have managed to cobble together a simple widget to turn the Master Sync option on and off. However when I click the widget it does nothing. Can someone advise me why?

This is the body of my Master Sync code:

public class MasterSync extends AppWidgetProvider {
/** Called when the activity is first created. */
@Override

public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {

final int N = appWidgetIds.length;

// now label the property of the button
boolean sync = ContentResolver.getMasterSyncAutomatically();

if (sync){

ContentResolver.setMasterSyncAutomatically(false);}
else
//
if (!sync){

ContentResolver.setMasterSyncAutomatically(true);
}

}}
