How to send ArrayList custom objects to bundle

Question

I have an application that uses a service to create an ArrayList of custom objects (MyObject) every x seconds. Then I want my activity to get this ArrayList array.

Currently, I plan that the Service sends a message to the Activity handler every time it finishes a data request. I want the message to the handler to contain the ArrayList MyObjects.

When creating a method in Activity to get this ArrayList from a message, I noticed that I couldn’t.

If i tried

msg.getData().getParcelableArrayList("myObjects")

Then the method I passed it to the expected one so that the ArrayList would not accept it. If I tried to make the results:

(ArrayList<MyObject>)msg.getData().getParcelableArrayList("myObjects")

I got an error: Cannot cast from ArrayList<Parcelable> to ArrayList<MyObject>

MyObject implements Parcelable, and I successfully dispatched an ArrayList from my service to my activity when my activity calls a service method to get it. However, I am trying to get away from having my survey show my service for this data.

1) How can I send an ArrayList inside a package in a message to a handler?

2) Is there another model that I must use so that my service updates data in my activity that may or may not be visible? I always want the data in my activity to be the last of the Service.

If the throw is a problem, just leave it, do not throw it, the error will disappear.
