Re: [android-developers] Re: bindService() does not create local service, but returns true

If I remember right, starting a service is asynchronous vs. the call to bindService, and so are the callbacks in ServiceConnection.

This means if you call the service on the next line after bindService, you'll get a null pointer exception.

Also make sure your Service subclass doesn't fail to instantiate (due to unresolved references or variable initializers). If the object can't be created, it will never get to onCreate.

This is the only serious logging I get in LogCat. Sometimes after that
I get a timeout on the Service, so maybe it is running, I just don't

get a reference to it.
