android - What is the best way to handle a large list data set with orientation changing? -

i have large data set base adapter in twitter-like app, consists of custom models (with nested references) quite large in themselves.

the issue i'm having is, when re-creating activity on orientation change, list quite slow populate (i'm passing data set through onsaveinstancestate)

i've looked changing way serialise models (currently using kryo has sped saving disk aspect), caching disk , reloading in oncreate, using setretaininstance(true) in list fragment, i've tried handling configuration changes in parent activity.

although latter quickest, it's last option want take there's lot of downsides handling orientation , mean having re-write chunks of code.

my question is, best practice of handing adapter repopulating on orientation?

i can foresee oom errors when serialising list pass through onsaveinstancestate

edit: possible duplicate best way persist data between orientation changes in android

one of options avoid recreating activity on orientation change: this, in app manifest set configchangesattribute this

<activity android:name=".mainactivity"           android:label="@string/activity_title"           android:configchanges="keyboardhidden|orientation|screensize">
