Memory fragmentation does not cause this; the Dalvik heap limit is enforced based on the actual active allocations.
Note that bitmaps are NOT include in the Dalvik heap based on what ddms reports, but they are included in the heap limit, so most likely you have a lot of bitmap data. (In HC this is changed and bitmap data is now allocated directly on the Dalvik heap.) On Thu, Feb 24, 2011 at 12:42 PM, Sheado <[email protected]> wrote: > Hello.
