创建数据库表Android中的问题

标签： java android sql sqlite

我编写了我的Android应用程序，它使用了一个数据库，这里是onCreate方法：

@Override
public void onCreate(SQLiteDatabase database) {
database.execSQL(CREATE_PARK_DETAILS);
insertParks(database);
database.execSQL(CREATE_DIARY);
}

在我的三星Galaxy S2上，它可以正常工作，就像从商店下载应用程序的其他100人手机一样。但是，一位用户在使用Android 2.3.4的索尼爱立信Xperia Arc（LT15i）上遇到了问题。所以我给其他人测试应用程序使用不同的手机，其中一个在Android 4.1上有同样的问题...一个SQLException。
之后我发现在这个设备上第二个表没有被创建，但只有第一个。
为什么呢？

CREATE_PARK_DETAILS：

CREATE TABLE cableparks (id int, name varchar(100), city varchar(100), state varchar(50), logo varchar(50), xCoord int, yCoord int, url varchar(100) DEFAULT '', street varchar(100) DEFAULT '', cap varchar(10) DEFAULT '', PRIMARY KEY (id));

CREATE_DIARY：

CREATE TABLE diary (id int, comment text, addDate long, PRIMARY KEY (id), FOREIGN KEY (id) REFERENCES cableparks (id));

logcat的：

GetFavorite方法：

public FavoritePark getFavorite(int parkId) {
    FavoritePark favorite = null;
    String query = "SELECT * FROM " + TABLE_DIARY + " WHERE " + ID + "=" + parkId + ";";
    try {
        Cursor cursor = database.rawQuery(query, null);
        try {
        if (cursor.moveToFirst()) {
            int commentIndex = cursor.getColumnIndex(COMMENT);
            String comment = cursor.getString(commentIndex);
            int addedIndex = cursor.getColumnIndex(ADD_TIME);
            Date added = new Date(cursor.getLong(addedIndex));
            favorite = new FavoritePark(comment, added);
        }
        } finally {
            try { cursor.close(); } catch (Throwable ignore) {}
        }
    } catch (Exception e) {
        Log.e("TAG", "getFavorite", e);
    }
    return favorite;
}
