incorrect concatentation of the android buildVersion
Android toggle buttons are inconsistent.  The XML attribute you define for a toggle event is called "onClick", but the event listener should hook into onCheckedChanged().

This should correct the odd swipe vs click events in #980.

Fix for #981 when the android framework returns NULL for getActivity()
Reduce badnwidth at low zoom level: 'trick' the map into showing lower zoom levels.
For example, if the map is at zoom level x, show the tiles for x - 4.
I don't do this exactly.
This code has a low/high zoom level switch, at
the high zoom level, behave as before this commit; at the low zoom
level, trick the map into showing very low resolution tiles, so only a
few tiles need loading to cover the map area.
