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

Answer 1

You can try the following. On each onStart, you can save the current orientation (take a look here). If it is the first onStart call, do nothing, on other calls, check if the orientation has changed and do what you need.

private int m_currentOrientation = -1;

public void onStart()
{
   int oldOrientation = m_currentOrientation; // 
   m_currentOrientation = getCurrentOrientation(); // As in the link above
   if ((oldOrientation != -1) && (oldOrientation != m_currentOrientation))
   {
       // Do what you need
   }
}
