Hi everyone!
I'm trying to make a simple, Intent-driven, "wifi status" app widget.
It simply displays a TextView with Wifi Status.
I overrided onReceive() method in AppWidgetProvider, so it could
trigger a "WifiManager.WIFI_STATE_CHANGED_ACTION".
Obviously i added the intentfilter in AndroidManifest.xml.
Then i created an "updateWidget()" method which updates the
RemoteViews on screen.
The problem is it doesn't work!
ACTUAL BEHAVIOUR:
The TextView only displays "DISABLING" (while Wifi is DISABLED) when
enabled, and then if I try to change wifi status, the TextView shows
ERROR (whick is widgettext default value that i set up).
Please Help!!!!
