Send data from widget to activity

I'm trying to send data from my widget to my activity. I've seen several topics about the widget side, but I didn't succeed to get the data in my activity.

See Passing data from widget to app

In my Activity I try to do in the onStart() method:

Intent intent = getIntent(); if(intent.getStringExtra("he")!=null) LogWrapper.debug(MainActivity.class, "DATA "+intent.getStringExtra("he")); else LogWrapper.debug(MainActivity.class, "DATA null"); 

But Intent is always null.

Widget provider side :

@Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { super.onUpdate(context, appWidgetManager, appWidgetIds); LogWrapper.info(DefibWidgetProvider.class,"in onUpdate!"); final int N = appWidgetIds.length; // Perform this loop procedure for each App Widget that belongs to this provider for (int i=0; i<N; i++) { int appWidgetId = appWidgetIds[i]; // Create an Intent to launch MainActivity Intent intent = new Intent(context, MainActivity_.class); intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK); intent.putExtra("he","Hello !"); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 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.widget_defib); views.setOnClickPendingIntent(R.id.refreshButton, pendingIntent); // Tell the AppWidgetManager to perform an update on the current app widget appWidgetManager.updateAppWidget(appWidgetId, views); } } 

Context : My app contains a Google map. I have 2 buttons in my widget, And I want to open the mainactivity and center the map on a special long/lat when the user click one of these buttons.

Could you help me to make this working ? thank you
