Why does AppWidgetManager update Intent of all RemoteViews for Widgets?
android,android-intent,widget,android-widget
Pass a unique int as the first flag (second parameter) of the pendingIntent, preferably widgetID. PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), uniqueID, clickIntent, PendingIntent.FLAG_UPDATE_CURRENT); This will cause android to not override the existing pendingIntent, but create a new one. Here's a link to a different post with a similar problem. ...

Why are these state variables in my AppWidgetProvider's onReceive null?

Your process may be terminated in between invocations of onReceive().

Static data members are only a cache, nothing more.
