作为Android Message IPC的一部分，通过Framelayout通过

我已经实现了 Messenger 作为两个 Android 应用程序之间的 IPC 机制。现在我想传递一个 FrameLayout 对象作为 android.os.Message 的一部分，

Message msg = new Message();
Bundle bundle = new Bundle();
bundle.putString("4", "2");
msg.setData(bundle);
msg.what = 42;
msg.obj = a_frame_layout_instance;

我想这样做，以便 app1 可以创建一个布局并对其进行膨胀，然后通过 IPC 将布局对象传递给 app2，然后 app2 可以添加/更新看法。

这会失败，因为 FrameLayout 不可分割。

java.lang.RuntimeException: Can't marshal non-Parcelable objects across processes.

有没有办法通过IPC传递FrameLayout实例？
是否有其他路径可以探索，以便 app1 创建视图，app2 更新视图？

I have implemented a Messenger as IPC mechanism between two android apps. Now I want to pass a FrameLayout object as part of android.os.Message

Message msg = new Message();
Bundle bundle = new Bundle();
bundle.putString("4", "2");
msg.setData(bundle);
msg.what = 42;
msg.obj = a_frame_layout_instance;

I want to do this so that app1 can create a layout and inflate it, and then pass the layout object to app2 via IPC, which can then add/update the view.

This fails because FrameLayout is not parcelable.

java.lang.RuntimeException: Can't marshal non-Parcelable objects across processes.

Is there a way to pass a FrameLayout instance via IPC?
Is there some other path that can be explored so that app1 creates the views, and app2 updates the view?
