Answer 1

Tried your code, the problem is with the library.

implementation 'com.android.support:appcompat-v7:{yourversion}' // appcompat library
implementation 'com.android.support:design:{yourversion}'

Answer 2

The problem is generated when you load CountriesSpecialitesActivity , in this Activity the layout loaded using setContentView() has an error like is described in the LogCat message:

Unable to start activity Component Info: android.view.Inflate Exception: Binary XML file line #2: Error inflating class android.support.design.widget.Coordinator Layout at android.app.Activity

The line #2 is:

<android.support.design.widget.CoordinatorLayout

check if your Activity CountriesSpecialitesActivity is extending from AppCompatActivity class.

class CountriesSpecialitesActivity: AppCompatActivity() {
