Excel 记录

在数据库术语中，记录包含有关已输入数据库的特定对象的所有信息或数据。在 Excel 中，记录通常组织在工作表行中，行中的每个单元格都包含一项信息或值。

基于 RecordFactory 的代码

http://www.docjar.com/html/api/org/apache/poi/hssf/record/RecordFactory.java.html

看起来您获得了一些与您拥有的 poi 版本不兼容的对象（在本例中为记录）。看起来您的记录不是 RecordFactory 中指定的任何类型。因此，您应该检查在服务器端如何创建这些文件以及与记录相关的代码。或者，如果它们是手动创建的，您应该检查 Excel 或 Open Office 版本，查看它们支持的记录类型，并将它们与您在 Android 设备上使用的库进行比较。

无法帮助说明为什么会引发异常，但我可以帮助您停止应用程序被强制关闭。

问题与ExceptionInInitializerError类相关联，该类不是由java.lang.Exception. 相反，它是从java.lang.Error超类派生的（参见ExceptionInInitializerError 声明）

所以解决方案是为这种异常添加一个显式的 catch 块，例如，以下之一：

catch(ExceptionInInitializerError e) // catch exactly this error

catch(Error e) // catch all Java errors (not exceptions!)

catch(Throwable t) // catch all Java errors and exceptions

请注意，必须将第一个和第二个 catch 块添加到现有的 catch 中，而第三个可以替换它们，因为它们是ThrowableJava类的超类。ExceptionError

对我来说，这是由proguard引起的。它删除/重命名了通过反射加载的记录类。

该规则有助于：

-keep class org.apache.poi.hssf.record.** { *; }

任务实例必须在 UI 线程上创建。

您应该在主应用程序线程中创建任务实例。它将解决您的问题。初始化事物的最佳方法是在您的项目中创建一个应用程序类并在该应用程序类中初始化您的任务。Application 类具有全局范围，可以维护应用程序的状态。
