I have a viewpager with at least 3 fragments. If the user inputs data into A, then B, then C and goes back to A that data is lost from A.

I think I read somewhere that this has to do with memory management and since fragments only connect to or store adjacent fragments it's killing A when I get too far away. However I wish to retain the life of each fragment even were I to have >3.

How can I tell the viewpager to never kill a fragment unless explicitly directed?

use 

setOffscreenPageLimit(int limit)

on the ViewPager object. "It sets the number of pages that should be retained to either side of the current page in the view hierarchy in an idle state."

    thanks a lot it is really helpful, I had 6 tabs and I wanted to maintain data of my first fragment and spent 2 days for it :) . – Antarix Apr 29 '14 at 05:16
  • This really helps. My fragments were losing states too. Any other tips you'd like to suggeat or anything I should keep in mind while using this property ? – Zen Jun 08 '14 at 07:51

    Note that if you want to do the opposite and make sure your fragments are killed and restored according to the lifecycle, this will not help, because the [minimum `limit` is `1`](https://stackoverflow.com/a/10073916/11683) meaning at least 3 fragments are kept alive at all times. – GSerg Nov 26 '19 at 09:34
