public abstract class LWUITActivity
It is not obvious how to map the midlet life cycle to the android one. It seems that we have to consider multiple issues: 1) possibly multiple instances of this activity class exist at the same time. 2) there is no garantee that the onDestroy() method is called but using the onPaused() method to trigger the midlet destruction is not really an option. 3) the activity (and in its current implementation the midlet) might be destroyed but the process might still be alive on the next invocation. static variables would survive in this case and cause unforeseen results. I think (1) is addressed in this implementation. We never really rely on a activity and use it only to initialize views. I see no solution for (2). To avoid problem (3) it seems that a solution would be to use the android:process attribute within the AndroidManifest.xml file and use a value starting with a colon ':' . http://developer.android.com/guide/topics/manifest/activity-element.html#proc
