ContentProvider database is not deleted

I am developing a content provider that stores its data in a SQLite database. During development, I need to change the schema or completely delete the database and restore it (I do not update the database at this stage of development).

I found a database file stored in / data / data // databases / app _db. When I pull it onto my desktop computer, I can use SqliteSpy to see its contents, and all is well. However, when I delete it, it is not always deleted really. Although I do not see the file in DDMS or ADB, my application still sees it.

I tried to make sure my application and service are not working when I delete the file, but it does not seem to help. In about half the cases, I delete the file, I need to restart the emulator so that it has an effect.

What can prevent file deletion?

I also saw this problem when writing unit tests for my ContentProviders. You must make sure that you kill the hosted process ContentProviderthat uses this particular database file. And just delete it.
