Answer 1

String query = "CREATE TABLE " + TABLE_NAME + "("+ 
       CLOUMN_ID +" INTEGER PRIMARY KEY AUTOINCREMENT, " + 
       CLOUMN_FIRST_NAME +" TEXT, " + 
       CLOUMN_LAST_NAME +" TEXT, " + 
       CLOUMN_GENDER +" TEXT, " + 
       CLOUMN_CITY +" TEXT " + 
       ");"; 
     db.execSQL(query); 

Answer 2

あなたのクエリを是正し、次のようにするだけTEXT後にカンマ（、）、またはあなたのデータ型を追加このように

String query = 
      "CREATE TABLE " + TABLE_NAME + " (" 
        + CLOUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT ," + CLOUMN_FIRST_NAME + " TEXT ," 
        + CLOUMN_LAST_NAME + " TEXT ," 
        + CLOUMN_GENDER + " TEXT ," 
        + CLOUMN_CITY + " TEXT" + ")"; 
        db.execSQL(query); 

次に古いアプリをアンインストールしてもう一度実行してください。
