Menu
I have an app that is using text-to-speech on start up. Everything appears to work perfectly and I have no problems when running the app. However, everytime the app starts I get a LogCat error that says I have a leaked ServiceConnection on my text-to-speech. Although this isn't causing a problem in function currently I am afraid of what my happen in the future if I continue to ignore the error. I suspect it is just misplaced coding but I don't have the experience to identify what is misplaced. I have included the LogCat and the offending java.

You should call myTTS.shutdown() when you are done with it, for example in your onDestroy.
