Situations when a Service's onDestroy() method doesn't get called?-Collection of common programming errors

I’m aware that a Service’s onDestroy() method may never be called but can someone tell me when such a scenario might occur?

Here are three off the top of my head:

• If the user Force Stops you from the Settings app

• If Android needs RAM in a hurry (e.g., to process an incoming phone call) and elects to terminate your process to free up that RAM

• You terminate the process from DDMS

Also, if your service crashes with an unhandled exception somewhere, Android may consider the service to be defunct and skip onDestroy(). I’m not sure about this one, as I haven’t specifically tried it.

But I’m wondering if it’s possible for a service to “go away” without onDestroy() being called, while the observers it created would live on and continue to receive changes.

Other than the unhandled-exception possibility I mention above, I am reasonably certain that if the process will be terminated in the conditions where onDestroy() is not called.
