[mono-android] Mono Stacktrace and ANR

[Andrew Sinclair]

David,

See my response to Piotr's "Random exceptions..." e-mail just now, I think
you're seeing the same problem.

Subject: [mono-android] Mono Stacktrace and ANR

I am getting an ANR from Android 5 seconds after seeing a mono stacktrace. I
would appreciate any guidance.

The code is in a ListView list adapter, trying to get a blob image from an
SQLite database. This same code sequence executes fine many times before
this failure. Heapsize is at about 18 MB, well within Kindle Fire 64 MB
limit. Is this a GC issue?

I have a longer trace available if desired.
