Okay, one last question ;)
I've noticed if I have one map in, say, "Activity1" and I call another
activity, "Activity2" which has a map within a tab of a TabHost - If I
press the back button and go from Activity2 to Activity1, the map in
Activity1 doesn't update i.e. load new tiles - only the map in the
TabHost of Activity2 will update from there on.
Also I have noticed I am getting OutOfMemory errors after I switch
between the Activity1 and Activity2 several times.
I tried overriding the onKeyDown method in the Activity of the tab in
Activity2 such as:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
Log.v("DEBUGTAG", "Back button pressed");
//Process.killProcess(Process.myTid());
finish();
return (true);
}
return (super.onKeyDown(keyCode, event));
}
If I just call finish(), I get the problem mentioned above, however if
I call:
Process.killProcess(Process.myTid());
... to kill Activity2 (the process holding the TabHost and which
created the tab content activity displaying the second map), the
problem doesnt seem to appear. However I guess this is a nasty hack -
it certainly causes the application to stutter before redisplaying
Activity1 again.
Theres a lot there to take in I know ;)
However what i'm asking is, is there a way to kill off Activity2
completely when pressing the Back button to return to Activity1 and
return full control to the first map? I believe I am making more and
more map objects when I launch Activity2 again and again and not
releasing resources when I finish with it?
Hope I havent confused you ;)
