Rotation issues are usually to do with the activity being recreated (i.e. onCreate is called again) as the screen size has changed. There is a config to disable this however: http://developer.android.com/guide/topics/resources/runtime-changes.html http://developer.android.com/guide/topics/resources/runtime-...

  If you mean configChanges, I would strongly recommend against it because it is a bad practice and it probably wouldn't work in this case anyway (no activity recreation = no multi-panel layout on a 7-inch landscape screen).

    Ah, sorry I haven't done Android dev in a while; would a better way be yock's onSaveInstanceState/onRestoreInstanceState then?

      Yes, something like that in combination with carrying over the existing list data with an retained fragment.

  It's usually better to implement onSaveInstanceState and onRestoreInstanceState. http://stackoverflow.com/questions/3542333/how-to-prevent-custom-views-from-losing-state-across-screen-orientation-changes http://stackoverflow.com/questions/3542333/how-to-prevent-cu...

3) Opening the comments of an article in portrait mode and then going landscape on the Nexus 7 crashes the app completely (presumably due to the multi-panel mode in sw600dp+ screens?)
