android.os.BadParcelableException：解组时出现 ClassNotFoundException：
android.os.BadParcelableException: ClassNotFoundException when unmarshalling:
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代码和日志猫，但我什至无法阅读logcat，我之前没有遇到过这样的问题，我什至不知道在哪里首先。
任何帮助将不胜感激。

我认为问题在于您在解组 SongDetails 列表时没有设置 class 加载器。
您可以通过以下方式阅读"Data1"：
if(bundle.getParcelableArrayList( "Data1" )!=null) {
bundle.setClassLoader (SongDetails.class.getClassLoader());
ArrayList < SongDetails > list = bundle.getParcelableArrayList( "Data1" );
// Rest of your code
}
