Recently I also have encountered with an interesting case while working with Android's Contacts Provider.

I needed to load photos of contacts from internal contacts database and according to the system architecture all of this data are delivered by queries to Contacts Provider.

As it works as a separate application - all kinds of data transferring are performed by using Binder mechanism and so Binder buffer comes into play here.

My main mistake was that I didn't close the Cursor with blob data gotten from Contacts Provider, so that the memory allocated for the provider increased and this inflated the Binder buffer until I got tons of !!!FAILED BINDER TRANSACTION!!! messages in my LogCat output.

So the main idea is that when you work with external Content Providers and got Cursors from them, always close it when you finish to work with them.
