Device Rotation

The state of the app is not retained upon device rotation.The spinner is initialized again which duplicates the values of the spinner. The card views are also initialized again and the card stack agin starts from student with id 0.

Reproduce the issue by rotating the device while the spinner and card stack are in use, then trace the activity or fragment lifecycle and the initialization paths for both views. Done means rotation retains the spinner state without duplicate values and preserves the current card position instead of restarting at student id 0.
