I have a really long collection with 10k items, and when running a toString() on the object it crashes. I need to use this output somehow.

    It seems that there is a hard limit of 16 MB heap space on Android apps that can only be worked around by altering the Android source. Your program has hit this limit: “Out of memory: Heap Size=15559KB”. You’ll need to figure out how to reduce your program’s memory usage. A nice guide to doing this is here.
