Android的SQLite应用程序将无法启动并崩溃后立即打开应用程序

-1

我目前在eclipse与android adt工作，无法让我的应用程序打开。我已经尝试清理应用程序并多次卸载它，我不知道还有什么可以使我的数据库显示信息。我正在模拟器上和我的摩托罗拉机器人仿生Android设备上尝试此操作。我很新的android编程，所以任何类型的帮助将不胜感激，我的代码可以在下面找到。 Eclipse的软件的细节是：Android的SQLite应用程序将无法启动并崩溃后立即打开应用程序

的Eclipse SDK 版本：4.2.1 版本ID：M20120914-1800

你试图选择与在“网站”列中的数据记录，但你的DATABASE_CREATE不添加此列。

切换电脑后，我的模拟器现在能够显示数据。唯一的是，除了“Hello World”，我的数据库中没有任何内容显示。我知道我必须更改activity_main.xml中的XML布局，但是有没有建议我应该使用哪种类型，无论它是列表还是文本？ – aNappyBoi

你需要空和手机之间的逗号。

private static final String DATABASE_CREATE = 
    "create table Business (_id integer primary key autoincrement, " 
    + "business text not null, address text not null, hours text not null," 
    + "phone text not null);";

即使在编辑之后，它仍然立即关闭 – aNappyBoi

您是否更改了DATABASE_VERSION的值。如果不是DatabaseHelper：onUpgrade（）将不会运行。如果您不想更改数据库版本号，则无论您使用哪种设备/仿真器，都需要清除应用程序的缓存/数据，否则应用程序将继续使用之前创建的旧数据库。 –

你可以清理你的项目并重新运行。 TJ的解决方案应该基于异常错误消息工作。 –

删除;从你创建的表字符串中尝试。在我的项目中，我没有使用;在创建语句的末尾。

private static final String DATABASE_CREATE = 
    "create table Business (_id integer primary key autoincrement, " 
    + "business text not null, address text not null, hours text not null," 
    + "phone text not null)";

我删除了;就在声明结束之后）。

我做了这个改变，并且在创建数据库时还没有新的事件。应用程序在打开时仍然关闭 – aNappyBoi

分号在创建语句中不应该有任何影响。所有的SQLite语句都应该以分号结束，否则整个字符串将被视为单个语句。由于create table语句后面没有其他语句，因此没有区别。 –

Android的SQLite应用程序将无法启动并崩溃后立即打开应用程序
