Android java.lang.RuntimeException:Parcelable在读取可序列化对象时遇到ClassNotFoundException

我正在尝试将

可序列化的

对象从一个应用程序发送到另一个应用程序

我的android应用程序有一个可序列化的类

public class MyClass implements Serializable

然后我把它的一个例子放在意图上

MyClass myObject = new MyClass();
intent.putExtra("payItem", myObject);
intent.setAction("com.mypackage.some.action");

当我给Startractiviy打电话时

startActivity(intent);

我的应用程序崩溃了

实际上，我的手机安装了两个应用程序，都注册了一个活动 使用相同的操作名称

<activity
        android:name="com.mypackage.MyActivity"
        android:exported="true"
        >
        <intent-filter>
            <action android:name="com.mypackage.some.action"/>
            <category android:name="android.intent.category.DEFAULT"/>
        </intent-filter>
    </activity>

我希望显示一个对话框，让我选择应该启动哪个活动，但我刚刚得到上面的错误。如果卸载其中一个应用程序，则不会发生错误，并且它会按预期运行

我的问题是

为什么不显示该对话框

这是坠机的原因吗

如果两个应用程序都已安装，那么有什么解决方案可以避免该错误

您是否正在尝试将可序列化对象从一个应用程序发送到另一个应用程序？@Sagar是的，这就是我想要的do@ArL在这种情况下，我认为目标应用程序不知道自定义序列化对象

MyClass
