title: Error inflating class material.bottomnavigation.BottomNavigationView
body: <p>I am trying to implement a BottomNavigationView, I am aware that there are multiple answers about the same question however none of them seems to work for me.</p>
  
  <p>I followed this <a href="https://material.io/develop/android/components/bottom-navigation-view/" rel="nofollow noreferrer">doc</a></p>
  
  <p>In preview mode, I get this error</p>
  
  <pre><code>IllegalArgumentException: Unknown color
  </code></pre>
  
  <p>When I run TestActivity I get an error inflating the class</p>
  
  <ul>
  <li>Drawables are inside <strong>res/drawable</strong></li>
  <li>Menu is inside <strong>res/menu</strong></li>
  </ul>
  
  <p>For what I was able to understand from answers in different posts this is a resources issue.</p>
  
  <p>I tried to delete every resource call, but even with just the width and height defined I still get the error.</p>
  
  <p><strong>TestActivity</strong></p>
  
  <pre><code>import android.os.Bundle;
  import androidx.appcompat.app.AppCompatActivity;
  import pt.myapp.android.myapp.R;
  
  public class TestActivity extends AppCompatActivity {
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.test);
