私はいつもそれを参照しています - 列の名前を1つの場所にのみ表示するようにagartクエリを完全にリッピングするチュートリアルの次のソースコード - ひどいです。 –

ここで、create tableクエリの問題があります。

String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_CONTACTS + "(" 
     + KEY_ID + " INTEGER PRIMARY KEY," + KEY_NAME + " TEXT,"+ KEY_PRICE + " INTEGER," 
     + KEY_START + " TEXT," + KEY_MANHOURS + " INTEGER," 
     + KEY_FINISH + " TEXT" + ")"; 

String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_CONTACTS + "(" 
     + KEY_ID + " INTEGER PRIMARY KEY," + KEY_NAME + "TEXT,"+ KEY_PRICE + "INTEGER," 
     + KEY_START + " TEXT," + KEY_MANHOURS + "INTEGER," 
     + KEY_FINISH + " TEXT" + ")"; 

更新これは、COLUMN_NAMEとCOLUMN_TYPE間行方不明のスペースを見つけることを試みます。
