Getting Exception ... Cannot take this action after onSaveInstanceState

The app throws an exception at random times and in radom devices. I don't understand when this happens. I just got too many crash reports on this.

Fatal Exception: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

I tried..

@Override
    protected void onSaveInstanceState(Bundle outState) {
        //No call for super(). Bug on API Level > 11.
        // override this method to avoide (java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState) this exception

    }

      

        
        
        
      

    

but it nonetheless gives the same exception.

MyActivity contains fragments. How do I get out of this?
