Re: Start Service at boot

Andy — Mon, 14 May 2012 03:36:19 -0000

Hi, I have the same situation, after I start the service form the
BroadcastReceiver runs once and then nothing, the service stoppes. I can't find it in the list ofrunning applications. What should I do? how do I fix it?I've found some answers about this and all of them were saing that in order to maintain the service active I have to lunch it from an activity.Well.. I don't want to start activity, I just want to run it just like a service.Is there a way?
