[android-developers] Re: ConcurrentModificationException in SQLite

This problem has raised its head again, even with the testing monkey
throttled back. It just becomes more infrequent at lower transaction
rates, which is what one would expect from a concurrency issue. I can
catch the exception, of course, but the real questions are 1) What DB
operation is causing it to happen and 2) What to do when the exception
occurs. It's hard to tell from the stack trace whether the DB was
reading, in which case I can swallow the exception and return some
default value, or writing, in which case I need to retry. Here's the
exception. Anyone have any ideas?
