Android - Activity Reload on Rotation -

i know duplicate question, , know when device rotated, oncreate method called again, , want keep this; don't want go through steps of overriding onconfigurationchanged or sub-classing application class because android doing reloading in best way (especially on saving current values , status).

however, have commands inside oncreate method don't want execute them if activity reloaded due rotation, there property/method can tell if oncreate triggered due first application start or due orientation change?

for example:
if(< oncreate triggered due orientation > == false)
// execute commands...
else
// nothing...

alternatively, have events in android triggered before oncreate or before onconfigurationchanged?

why not store current orientation in sharedpreferences , compare current orientation stored value in oncreate (and save new orientation sharedpreferences)?

that should provide functionality require, unless i've misunderstood something.
