android.os.BadParcelableException : ClassNotFoundException when unmarshalling:

Question

我不知道为什么会这样，我无法重现它。它在控制台中。

我真的很抱歉只输入了代码和日志猫，但我什至无法阅读日志猫，我之前没有遇到过这样的问题，我什至不知道从哪里开始。任何帮助将不胜感激。

这是日志猫，

            click_no = bundle.getString( "click_no_playlist" );

Answer 1

我认为问题在于您在解码 SongDetails 列表时没有设置类加载器。

您可以执行以下操作来读取 "Data1":

if(bundle.getParcelableArrayList( "Data1" )!=null) {
    bundle.setClassLoader (SongDetails.class.getClassLoader());
    ArrayList < SongDetails > list = bundle.getParcelableArrayList( "Data1" );

    // Rest of your code
}
