Question

I am converting my app with multiple list views into a ViewPager app. Need to support 2.1+ so I am using the compatibility library. Are there any gotchas related to the use of ViewPager? Memory issues or crashes that I need to be wary of? My app is very heavily downloaded, 1M+, so I don't want to get biten if there is some known issues out there. I saw there are some options to keep the pages in memory, are there any dangers with this as far as memory usage?

No correct solution

OTHER TIPS

Just imagine (or if you prefer, simulate) all of your app's tabs/lists running simultaneously, because that's what ViewPager does. They're all kept in memory and running. If it gets too RAM-heavy, consider unloading a fragment far away from the user's current position, and reloading it when the user gets close again.
