Since Android keeps the DVM around even after I terminate my services and activities, I thought it would be a nice place to store the state via a singelton object to save flash writes. Then your service should not be in memory to keep the state. You are > wasting RAM and harming the user.

Since finalize() wasn't called in the singelton, I tried by using the smallest possible service to catch the onDestroy() to preserve the state. It is not to waste RAM, since Android anyway keeps the objects in the DVM even with every activity and service therein terminated. Why not make use the windfall?

The question remains, why not onDestroy(), a shutdownhook and/or finalize() before killing of the DVM? -- Mikael Kuisma -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
