This isn't entirely making sense to me, but it's possible we're not seeing something. At the least it's saying you've got 7-8MB of external allocations, presumably for the map tiles. (I think there's 1MB of common resources that the "zygote" grabs before you begin.) A soft limit of 13MB means the heap was pushed out that far at some point (remember, the actual extalloc computation is vs. the footprint size, which sadly isn't displayed). If it's stuck out there due to fragmentation, dlmalloc's notion of the footprint size could be smaller than that. The part that's a bit confusing for me is that it appears to push the soft limit out, which it would only do if something didn't fit anywhere in the heap (again, possible for a large object when there's lots of fragmentation). (At one point we had a graphical heap display in DDMS, but it's been disabled since launch and seemed a little broken the last time I fiddled with it. Was useful for looking at fragmentation.) Can you crank up the verbosity in the script (debug=True in handleGcInfo)? That'll show among other things the current bytes allocated, which might be revealing. If the total size of all objects is much less than the soft limit, *and* dlmalloc is ignoring the fragmented areas during the footprint size calculation, then these numbers might make sense. At any rate, this raises questions: (1) how did the soft limit get that high? (2) why is there 7MB of stuff in the external alloc area? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
