you need close database activity's ondestroy method. assuming you've written application using "database helper" class, in android tutorials such notepad, ought work as-is. (otherwise, replace mdbhelper.close() appropriate call close database connection.)

public class myclass extends activity { // ...     @override     protected void ondestroy() {         super.ondestroy();         mdbhelper.close();     } }
