Question

Can I use Android’s sharedpreferences to pass a Java object between different activities?

Answer 1

“Bundles” are probably the best way to go:

Intent and Bundle are two classes to transfer object’s from one
activity to another activity. You can create bundle object and put
them into intent

If you want to pass an “object” in your Bundle, then the object must implement “Parcelable”:

Yet another alternative is to use global state:
