第一次插入行时它可以正常工作。但是在同一设备上安装应用程序后（从 eclipse 安装而不从设备卸载应用程序）并尝试插入新行会引发异常

创建表：

    public void onCreate(SQLiteDatabase db) {
    String CREATE_CONTACTS_TABLE = "CREATE TABLE " + TABLE_USER_DATA + "("
            + KEY_ID + " TEXT PRIMARY KEY," + KEY_TIMESTAMP + " TEXT,"
            + KEY_JSON_DATA + " TEXT" + ")";
    db.execSQL(CREATE_CONTACTS_TABLE);
}

插入：

    public void addJsonData(JSONDataStore dataStore) {
    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues values = new ContentValues();
    values.put(KEY_ID, dataStore.getKey());
    values.put(KEY_TIMESTAMP, dataStore.getTimeStamp());
    values.put(KEY_JSON_DATA, dataStore.getJsonData());

    db.insert(TABLE_USER_DATA, null, values);
}

升级：

    @Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_USER_DATA);

    onCreate(db);
}

插入时的异常：

    db.insert(TABLE_USER_DATA, null, values);

该错误告诉您您正在尝试ID为定义为的列创建具有相同值的两行PRIMARY KEY。为了让 sqlite 为您创建自动增量 ID 值，只需删除此行。-

values.put(KEY_ID, dataStore.getKey());

并将列声明为INTEGER.
