Error inflating class ImageButton

Question

I have an app which has fragment and image button on that. The problem is it's working on and above 5.0 but not below 5.0. The min sdk version is 17.

Not getting what's wrong here. I am getting 2 exceptions.

One is RuntimeException for image button. Second is ResourceNotFoundException for fab selector file.

Log : 1st exception --

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.siddhi.timetablelayout/com.example.siddhi.timetablelayout.MainActivity}: android.view.InflateException: Binary XML file line #16:

Error inflating class ImageButton

2nd exception --
