Log.d(LOG_TAG, "onUpdate(): ");
for (int appWidgetId : appWidgetIds) {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:"+number));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, callIntent, 0);
// Get the layout for the App Widget and attach an on-click listener to the button
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.caller);
views.setOnClickPendingIntent(R.id.callButton, pendingIntent);
// Tell the AppWidgetManager to perform an update on the current App Widget
appWidgetManager.updateAppWidget(appWidgetId, views);
