Hello Mark, I have short question to your example :
If I understood it right, the Broadcast from the WeatherPlusService will not start up the WeatherPlus Activity ? So how must the example be changed, that the first broadcast will startup the activity and the next ones are normal broadcast to send the new status to the activity. I know that I can use startActivity( Intent ) to startup the activity ..and use then sendBroadcast(Intent), but you cannot know, whether then your Activity is still running. I have the requirement, that when the devise status changed I have to popup an alert dialog. Must this really be done by the Service ? Thanks !
