OS delete files

[derez]

My nav program uses map tiles which are stored in a directory under external root.
When the program fails (application close, not reported error) the map file which was used ( = was read to a bitmap) sometimes is deleted from the directory.

How can these files be protected against deletion ?

I don't see any reason for the image files to be deleted. If your application fails with no error you should check the unfiltered LogCat and see if there are any messages.

I'm talking about an application running on a device, not connected to the IDE. How can I check logcat ?

There are device applications that allow you to see the logs. Try to search the market.
