I wondering where and when I should open/close my SQLiteDatabase connection in my AsyncTaskLoader. I don't feel like i fully understand the lifecycle of a Loader, so I'm afraid that I might run into some memory leaks/NullPointerExceptions if I don't to this right. I currently open up my SQLiteDatabase in the constructor of my loader: private class SQLiteCursorLoader extends AsyncTaskLoader<Cursor> { private String _queryString; private SQLiteDatabase _db; ... public SQLiteCursorLoader(Context context, String queryString) { super(context); _queryString = queryString; _db = MySQLiteOpenHelper.getWritableDatabase(); } .... } But where do I close the connection again?
