android - Is that possible to check was onCreate called because of orientation change?

Question

I need to act differently in onStart() method depending on how onCreate() was called in result of orientation change or not. Is that possible to check it?

Actually what I need is to do something when activity starts except a case when user changes orientation.

I need to clearly distinguish cases when user just switched to another application and returned back OR he changed device's orientation.

Following Nahtan's idea I wrote this:

in onCreate():

if ( (oldConfigInt & ActivityInfo.CONFIG_ORIENTATION)==ActivityInfo.CONFIG_ORIENTATION ) {
    // ... was rotated
} else {
    // ... was not rotated
}

in onDestroy():

super.onDestroy();
oldConfigInt = getChangingConfigurations();
