Question

我是Android开发人员，我正在尝试使用Serializable将Activity个对象发送给另一个Bundle。但是，我得到以下内容 - Parcelable encountered ClassNotFoundException reading a Serializable object为错误。

这是什么原因以及如何解决？

以下是代码段：

Bundle previousData = new Bundle();
previousData.putSerializable("GetVehicleInfo_AllTrims", trimsObj);// trimObj is a serialized object
Intent detailsIntent = new Intent(androidScrolbleTabbar.TABBAR_PUSHVIEW);
detailsIntent.putExtras(previousData);
detailsIntent.putExtra("ActivityIdentifier", ManualScreenNav2.viewIdentifier);
detailsIntent.putExtra("className", ManualScreenNav2.class.getName());
sendBroadcast(detailsIntent);

以下是完整的堆栈跟踪：

错过了再加一点，我有两个具有相同功能的应用程序，每个应用程序具有相同的类GetVehicleInfo_AllTrims，它是一个pojo类。当我在前台运行一个应用程序时，生活在后台的另一个应用程序因上述错误而崩溃。

Answer 1

您好找到问题的根本原因并解决了问题。

在两个应用中，我们使用相同的BroadCastReceivers及其intent过滤器。由于此问题，运行时无法为应用程序找到合适的接收器。

我修改了两个应用程序的intent过滤器，现在工作正常。

Answer 2

java.lang.ClassNotFoundException: com.halcyon.ui.redbumper.entities.RBGetVehicleInfoByVin_AllTrims

这是什么原因

造成这种情况的原因是未找到类com.halcyon.ui.redbumper.entities.RBGetVehicleInfoByVin_AllTrims。

我该如何解决？

在应用程序的CLASSPATH上使该类可用。

传递Serializable时ClassNotFoundException
