Near as I can tell from some basic MAT sleuthing, what you are seeing is a cache 
maintained by Maps V2 of downloaded map data. The cache seems to be bigger if you pan
and zoom a lot. The cache shrinks if you leave the map and return to a fresh map later
on. I could not get N caches from N times launching the map activity of your sample
app, and the cache size ebbed and flowed depending upon what the user did.

Alas, this cache is unconfigurable, AFAIK, in terms of how big it is, when it gets
cleared out, does it spill over to disk, etc.

So, by default, all you can do is leave aside a healthy chunk of your heap space for 
Maps V2 to play with, and take steps to stay within this smaller subset of heap.

If you wanted to experiment, you could try calling clear() on GoogleMap, or
onLowMemory() on your SupportMapFragment, to see if any help reduce this cache size.
