  <p><strong>What's happening?</strong></p>
  
  <p>The library 'com.google.android.material:material:1.2.0-alpha04' tries to download the androidx.cardview:cardview:1.0.0 dependency. But this does not download:</p>
  
  <p>Label: "Could not find cardview.aar (androidx.cardview:cardview:1.0.0).
  Searched in the following locations:
      <a href="https://dl.google.com/dl/android/maven2/androidx/cardview/cardview/1.0.0/cardview-1.0.0.aar" rel="nofollow noreferrer">https://dl.google.com/dl/android/maven2/androidx/cardview/cardview/1.0.0/cardview-1.0.0.aar</a>"</p>
  
  <p>The point is: When I manually try to download from <a href="https://dl.google.com/dl/android/maven2/androidx/cardview/cardview/1.0.0/cardview-1.0.0.aar" rel="nofollow noreferrer">https://dl.google.com/dl/android/maven2/androidx/cardview/cardview/1.0.0/cardview-1.0.0.aar</a> it perfectly downloads. But the IDE cannot.</p>
  
  <p>So, I'm tried to manually insert the androidx.cardview:cardview:1.0.0 library. I donwloaded the cardview-1.0.0.aar file and successfully inserted to A.Studio. </p>
  
  <p>But I need the material library in order to use TabLayout. So, when I include (implementation 'com.google.android.material:material:1.2.0-alpha04') this fails againg saying it cannot resolve at <a href="https://dl.google.com/dl/android/maven2/androidx/cardview/cardview/1.0.0/cardview-1.0.0.aar" rel="nofollow noreferrer">https://dl.google.com/dl/android/maven2/androidx/cardview/cardview/1.0.0/cardview-1.0.0.aar</a>.</p>
  
  <p>I'm trying to see if there is any chance to avoid that the material library stop calling out the cardview dependency, don't know if possible.</p>
  
  <p>Also, if I insert ( implementation 'androidx.cardview:cardview:1.0.0') A Studio says cannot resolve this link. </p>
  
  <p>Please, any advice? Thanks very much</p>
