garbage-collection

Let's say I start from activity A -> activity B. While in activity B I press home to exit. After a long time, gc may be called because other apps take higher priority. My question is, which of the following type of data will be garbage collected (I'm pretty sure static fields can be garbage collected any time but I'm not sure about these):

i) fields that are declared final or static final

ii) intent and its data that I passed from activity A to activity B

iii) onSavedInstanceState when orientation is changed during the app running

I ask this because I want to ensure that my app won't crash when I restore activity B from background after a long period.
