You need to close the database from your activity's onDestroy method. Assuming that you've written your application using a "database helper" class, as in some Android tutorials such as Notepad, then this ought to work for you as-is. (Otherwise, just replace mDbHelper.close() with the appropriate call to close your database connection.)

public class MyClass extends Activity {
// ...
    @Override
    protected void onDestroy() {
        super.onDestroy();
        mDbHelper.close();
    }
}
