Я создал приложение на мини-андроиде 5. Но я хочу запустить его на 4.4 android. Поэтому я скопировал файлы с первого проекта на второй и исправил такие вещи, как AndroidManifest. Когда я компилирую первую версию evrythink, все нормально, но в версии, которая должна работать с android 4.4, я получаю SQLite exeption «нет такого столбца». Код:такой код ошибки столбца не работает при использовании 4.4 Kitkat
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_select, container, false);
helper = new MobilnaPytajkaDatabase(getContext());
db = helper.getWritableDatabase();
cursor = db.query("QUIZ_TABLE", new String[]{"_id", "QUESTION"},
"TYPE=0", null, null, null, null, null);
lista = (ListView) view.findViewById(R.id.listview);
if(cursor.moveToFirst()) {
try {
CursorAdapter ca = new SimpleCursorAdapter(getContext(),
R.layout.whitetextlayout1, cursor,
new String[]{"QUESTION"}, new int[]{R.id.text1},
0);
lista.setAdapter(ca);
lista.setOnItemClickListener(listener);
} catch (SQLiteException e) {
;
}
return view;
}
else
return inflater.inflate(R.layout.emptylist, container,false);
}
