How to store nested Arraylists in a Bundle in Android

I have this object in my Android App source code:

ArrayList<ArrayList<MyObject>> rsp

and i want to store it in a Bundle and use it in OnSaveInstanceState() method in my activity. Then i want to retrieve it from the bundle, too.

Should i use json? Is there another way?

Solution

  • you can use Parcelable to store the data in Bundle during OnSaveInstanceState()
