File Descriptors
This is perhaps the sneakiest Android resource leak. Each app has a hard limit of 1024 file descriptors. Fortunately, 1024 file descriptors is an extremely generous limit, which should not be encountered during day-to-day development. Unfortunately, when coding errors introduce file descriptor leaks, the resultant crashes—Android immediately closes any app which exceeds its file descriptor allocation—do not put any useful debugging information in the logs. It is worth investigating any crash which shows those symptoms as a file descriptor leak.
