Error inflating class android.support.design.widget.FloatingActionButton

Question

My app crashed because

Error inflating class android.support.design.widget.FloatingActionButton

This is my code in the XML

Answer 1

Make sure the library from which you declared the FloatingActionButton in the activity is the same as the one used for the layout markup

For example have

import com.google.android.material.floatingactionbutton.FloatingActionButton; in the activity and com.google.android.material.floatingactionbutton.FloatingActionButton as the tag for the layout
