Are you talking about Services and Activities or something else? I never had any problems with Services and Activities using them and connecting to them, using them etc. but I can see how an inexperienced dev could get this wrong. Same problem goes for not understanding detachable threads in other languages (eg. keeping a reference/pointer to them and attempting to use them when you have no idea when they've finished) but that's a newbie problem. I wouldn't say that the language or design of threads was at fault if I was using it wrong.
