The variable that i need to access staticly is a the own MapActivity
instance variable because i need to pass it to another mapView objects
from other activities
public class OsmMapActivity extends MapActivity {
public static OsmMapActivity instance;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
View v = new View(this);
setContentView(v);
instance=this;
So i am holding a MapActivity instance in a static field of the
MapActivity itself because i need to access it by other activities and
use that variable in some MapView objects. It is a hard need for a
"special" huge app
Then, the variable will be referenced on my active activity, but... it
will be deleted or will be alive if the Android O.S. deletes the
nonvisible MapActivity ??
