Question

Another design question for you
If I have 5 activities that can result from one activity
A->B
A->C
A->E
…. Etc

And activity A has values that need to be passed to all other activites, then do you recommned passing them through intent or should I just have a global static variables in activity A and read the values in any other activity?

Thank you

Answer 1

Definitely don’t use static public variables.

You should use:

• SharedPreferences or DB for data that should be persisted (cached)
• Intent extras if data is needed in some part of app (couple of activities)
• Application inheritor for application-wide data, that shouldn’t be persisted.
