dalvik.system.NativeStart

Question

我已经创建并发布了我的android应用程序。这很简单。它在我的手机游戏笔记上运行得很好，但是我得到了类似的错误：

Answer 1

在准备“创建表登录时(id整型主键、名称文本、电子邮件文本唯一、uid文本、created_at文本、电子邮件文本唯一)”。

在创建表时，您已经在SQL中使用了两次电子邮件列名。

sqlite returned: error code = 1, msg = duplicate column name: email 04-14 02:15:33.030: E/Database(301): Failure 1 (duplicate column name: email)

希望这能帮到你。
