I should have said more clearly that in the case of these external allocations it's acting like it can't grow the heap--i.e. there's a hard limit that it hits against. Why is that the case? As many threads on this subject for the last year have attested to, it's not a question of hitting the overall heap limit, it's a question of the external allocation failing due to some other limit that doesn't seem to be flexible. > The standard maps app uses the same library, and at this point doesn't have > such problems as far as I know.

Our allocated memory varies between about 3-5 MB, and allocations fail at various times when memory is at various points. Isn't it a question not of overall memory usage but of hitting whatever heap limit the external allocations care about? I'm not saying there's a bug in the map framework, I'm saying there's a problem with the external allocation design. I think I saw Andy refer to it as a "hack" elsewhere, and it is clearly a problem for very many applications. When it's my code I can try to work around it, and I've successfully done that in another app by retrying allocations, freeing memory and GCing in between retries. But I have no control over the map framework or any other code that is stumbling over this limitation, and that's the big problem. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
