keine solche Spalte Fehlercode funktioniert nicht bei der Verwendung von 4.4 Kitkat

Question

Ich habe eine Anwendung auf min Android 5 erstellt. Aber ich möchte es bei 4,4 android ausführen. Also kopierte ich Dateien vom ersten Projekt in die zweite und korrigierte Dinge wie AndroidManifest. Wenn ich erste Version kompiliere funktioniert evrythink ok, aber auf Version, die mit Android 4.4 arbeiten sollte, bekomme ich SQLite Ausnahme "keine solche Spalte". Code:

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); 
    } 

SQLite offen Hilfsklasse:

package com.nieruchalski.mobilnapytajkaforkitkat; 

import android.content.Context; 
import android.database.sqlite.SQLiteDatabase; 
import android.database.sqlite.SQLiteOpenHelper; 

public class MobilnaPytajkaDatabase extends SQLiteOpenHelper { 
    public final static int DB_VERSION = 2; 
    public final static String DB_NAME = "QUIZ_DATA"; 

    MobilnaPytajkaDatabase(Context context) 
    { 
     super(context, DB_NAME, null, DB_VERSION); 
    } 

    @Override 
    public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) { 
    } 

    @Override 
    public void onCreate(SQLiteDatabase sqLiteDatabase) { 
     sqLiteDatabase.execSQL("CREATE TABLE QUIZ_TABLE (_id INTEGER PRIMARY KEY AUTOINCREMENT, " 
     + "QUESTION TEXT" 
     + "ANSWER TEXT" 
     + "TYPE INTEGER);"); 
    } 
}

Answer 1

nichts mit Kitkat wirklich zu tun. Sie vermissen nur Kommas , zwischen Spalten Spezifikationen in MobilnaPytajkaDatabase#onCreate(). Fügen Sie sie dort hinzu und deinstallieren Sie Ihre App, um die alte Datenbank zu entfernen und eine neue zu erstellen.
