Android out of memory error

Question

I have an app that needs to synchronize 3 database tables that it holds with the Android contacts list.

I loop through the contacts list and I create a custom object for each row returned and compare that objects properties with what i have stored in my apps table for that contact.

This task is performed in an Async task.

It works fine for me the first time it runs, but if I leave the app and come back more than once it breaks and the following errors are returned. Any ideas?

E/IMemory(31018): cannot dup fd=1023, size=2097152, err=0 (Too many open files)
android.database.CursorWindow.native_init(Native Method)

These two lines suggest you are messing up something with Cursors, like not closing etc.,

I would suggest close all cursors properly and observe the behavior of app.
