android - 传递 Serializable 时出现 ClassNotFoundException

Question

我是一名 Android 开发人员，我正在尝试使用 Bundle 将一个 Serializable 对象发送到另一个 Activity。但是，我得到以下信息 - Parcelable encountered ClassNotFoundException reading a Serializable object 作为错误。

这是什么原因造成的，我该如何解决？

下面是代码 fragment :

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);

下面是完整的堆栈跟踪:

错过了再补充一点，我有两个具有相同功能的应用程序，每个应用程序都有相同的类 GetVehicleInfo_AllTrims 并且它是一个 pojo 类。当我在前台运行一个应用程序时，另一个在后台运行的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它。

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

我以不同方式修改了两个应用的 Intent 过滤器，现在运行良好。
