これらのエラーから、私はffしか理解できません:

03-03 09:47:44.569: E/AndroidRuntime(333):  at com.example.filipinocuisine.SQLiteAdapter.openToWrite(SQLiteAdapter.java:40)
03-03 09:47:44.569: E/AndroidRuntime(333):  at com.example.filipinocuisine.menucategory1a1.onCreate(menucategory1a1.java:22)

このコードが含まれています：

私のmenucategory1a1にはffが含まれています：

     mySQLiteAdapter.openToWrite();

私のアダプターで：

     public SQLiteAdapter openToWrite() throws android.database.SQLException {
       sqLiteHelper = new SQLiteHelper(context, MYDATABASE_NAME, null, MYDATABASE_VERSION);
       sqLiteDatabase = sqLiteHelper.getWritableDatabase();
       return this;

コードが間違っている可能性がt find whatあります。提案をお寄せいただきありがとうございます

エラーはここにあります

_idINTEGER PRIMARY KEY AUTOINCREMENT

そのはず

_id INTEGER PRIMARY KEY AUTOINCREMENT

_idとの間のスペースを忘れましたINTEGER

マネーショットは次のとおりです。

03-03 09:47:44.569: E/AndroidRuntime(333): Caused by: android.database.sqlite.SQLiteException: AUTOINCREMENT is only allowed on an INTEGER PRIMARY KEY: create table BEEFTAPA (_idINTEGER PRIMARY KEY AUTOINCREMENT, Content text not null);

具体的には：

(_idINTEGER PRIMARY KEY AUTOINCREMENT

ヘルパー コードで、と" "の間のスペース ( )が欠落していると思います。_idINTEGER
