Hello我的代码给出了以下两个异常，我似乎无法识别或解决问题，我已经给出了我确定错误存在的类，如果你需要我项目中的其他类[请参阅进口]让我知道。谢谢

我是android新手，很抱歉低级错误
答案 0 :(得分：0)
尝试更改此内容：
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" +
"";
}
对此：
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)"
}
我删除了所有\“和\ n字符。现在它应该正常工作。
因为，例如：此\"_id\"会错误地尝试插入"_id"而非_id。
此TEXT\n不是有效的SQLite类型，而此TEXT是
