Quick beginner's question. If I have a long list of objects and I want to start another intent (to save them to a file for example), how should I pass the list to the intent?

Your objects should implement Parcelable (check

Parcelize

in Kotlin). Or Serializable.

yea parcelable is better option than serialization

Yes, thank you! Sorry for the stupid question but why shouldn't I simply make the list static?

lol Giulio, that would just be the beginning to alot of messy untestable code

I would avoid sending list of objects in an intent unless you know it will be small. You will run into the parcel limit size

Hi indeed I am making the list static. Let's say I want a new intent where I gather other data from the user that is needed to complete the file structure before saving it...

Def avoid passing a list of objects through intents...you will run into crashes that you won't be able to easily diagnose due to parcel exception

Already done a static list without issues. Avoided the extraPut for all these items. I agree with you. Do you want to know practical reasons for crashes? Intents not correctly declared in the manifest and similar weird stuff of android apis... ids not found in the getView of an array list adapter... items overflowing a linear layout... etc, really fixing crashes has become my strength And no, not even one crash due to my static list 😉
