问题描述
|
好吧，我想做的是在第一次安装时对我的应用程序进行设置。因此，在第一次访问中，我的应用程序具有访问CallLog，检索所有数据并将其插入应用程序数据库的服务。
我有一个列“ 0”，我想插入呼叫的时间戳。但是，当我尝试插入时，它说该表没有名为timestamp_的列，并且该列的名称明确地写在sql字符串中。我不知道为什么要这么做。
我的CREATE TABLE字符串写在ѭ1中，我访问该字符串并将其拆分成每一行。
这是服务的代码，sql字符串，然后是DataHandlerDB的代码，后面是创建数据库的方法。
我的服务：

解决方法
我认为这是Java和SQLite之间的绑定代码中的错误。您可以尝试将\“ timestamp_ \”重命名为\“ time_stamp \”进行测试吗？
