Android 从收件箱删除短信时出现异常

我正在写一个从收件箱中删除短信的项目。大多数情况下，它工作正常，但有时会出现奇怪的异常。这是异常的堆栈跟踪：

这是我从收件箱中删除短信并获得异常的一行：

l_contentResolver.delete(deleteUri, "address = ?" +" AND "+"date = ?",
                    new String[] {PhoneNumber,String.valueOf(DateandTime)}); 

这是deleteUri：

Uri deleteUri = Uri.parse("content://sms");

这是l_内容解析程序：

ContentResolver l_contentResolver = activity.getContentResolver();

我搜索了很多关于此异常的信息，但没有在我的代码中找到原因。请帮助我。提前感谢。

我认为这不是您代码中的问题。如果只在极少数情况下发生，则是管理SMS的ContentProvider中的错误

因为SMS API不是Android API的公共部分，所以我认为没有关于这个问题的文档，也没有将其标记为Android Bug的地方

可能稍后再尝试删除该邮件。
