  <p>i just want to be able to use
  <strong>TabLayout</strong> as when i use it it says 
  cannot resolve 'TabLayout' symbol. </p>
  
  <p>and when i try to import it</p>
  
  <p>import android.support.design.widget.TabLayout;
  says also  cannot resolve 'TabLayout'</p>
  
  <p>also i searched for that error and it results to install the android support library which i cannot find </p>
  
  <p>here is a search for that
