Hello Dianne, Speaking of clearing the application's cache data...what is the difference in deleting the cache when the application exits as opposed to clearing the cache data by the user himself? I have 2 use-cases:
1. When the application exits gracefully, I should be able to clean all the data that i had created/stored during the lifetime of the application. 2. When the application crashes unexpectedly, or due to an abnormal event, the data should not hang on forever. (I believe this is taken care of by the framework ? ) Thanks On Sun, Jul 26, 2009 at 4:29 AM, Dianne Hackborn <[email protected]>wrote: > You generally shouldn't need to clear it, since the point of that is it > allows the system to delete those files to free up storage when needed. > > That said, you do want to keep the amount of data in your cache at a > reasonable size rather than just throwing stuff in there and letting it grow > indefinitely.
