運行時異常 Android 4.3/4.4

Question

你好我的代碼給出了以下兩個例外，我似乎無法識別或解決問題，我已經給出了我確定存在錯誤的類，如果你需要我的項目中的其他類[查看導入]讓我知道. 謝謝

注意 應用程序崩潰通常是在 Google Playstore 更新應用程序或有人使用 Android 4.3 和 4.4 版本時

我是 android 新手，很抱歉出現低級錯誤

Answer 1

嘗試改變這個：

public static String getCreateQuery() {
    return "CREATE TABLE application (\n" +
            "    \"_id\" INTEGER PRIMARY KEY AUTOINCREMENT,\n" +
            "    \"package\" TEXT,\n" +
            "    \"orientation\" TEXT,\n" +
            "    \"category_id\" INTEGER NOT NULL DEFAULT (1),\n" +
            "    \"icon\" INTEGER,\n" +
            "    \"name\" TEXT\n" +
            ")\n" +
            "";
}

對此：

public static String getCreateQuery()
{
    return "CREATE TABLE application " +
            "_id INTEGER PRIMARY KEY AUTOINCREMENT, " +
            "package TEXT, " +
            "orientation TEXT, " +
            "category_id INTEGER NOT NULL DEFAULT (1), " +
            "icon INTEGER, " +
            "name TEXT)"
}

我刪除了所有的 \\" 和 \\n 字符。現在它應該可以正常工作了。

因為，例如：這個\\"_id\\"將錯誤地嘗試插入"_id"而不是_id 。
而這個TEXT\\n不是一個有效的 SQLite 類型，而這個TEXT是
