嘿朋友我已经添加了code.Please检查出来，并告诉我如何解决该错误...请帮助。 – TechHelper 2012-03-03 21:09:04

这还不够，我们需要你的'数据库'类的代码 – 2012-03-04 09:33:47

需要看到你的代码，但我怀疑你在启动时没有在正确的位置调用SQLiteOpenHelper。

可以在onCreate（）中创建SQLiteOpenHelper对象，但在您需要读取或写入之前不要打开数据库。在内容提供商，标准模式是建立在ContentProvider.onCreate（）的 SQLiteOpenHelper，但不叫getWriteableDatabase（），直到访问的用武之地。

你可能在一个叫getWritableDatabase()（或getReadableDatabase()）方法onCreate()或onUpgrade()你的执行SQLiteOpenHelper。 getWritableDatabase()致电onCreate（或onUpgrade），所以如果你有getWritableDatabase()调用其中一种方法，你会遇到麻烦。

这些方法有一个参数（SQLiteDatabase对象），您必须使用做你的数据库逻辑（这样你就不能调用getWritableDatabase()（或getReadableDatabase()在那里）。
