title: Android Studio adds both @androidx.annotation and @android.support.annotation problem
body: <p>I updated Android Studio to version 3.2.0.</p>
  <p>When I accept any change from <strong>list of suggestion</strong> or <strong>alt + enter</strong>.</p>
  <ul>
  <li>Problem is <code>@androidx.annotation</code> auto created.</li>
  <li>Thus suggestions method have two annotation <code>@androidx.annotation.Nullable</code> and <code>android.support.annotation.Nullable</code>.</li>
  <li>I don't want to manually remove this unwanted suggestion, so what can I do to have only <code>android.support.annotation</code>?</li>
  <li>Also <code>androidx.annotation</code> package is not added in my app. and I don't want to add <a href="https://mvnrepository.com/artifact/androidx.annotation/annotation?repo=google" rel="noreferrer">androidx.annotation</a>.</li>
  </ul>
  <p>See example.</p>
  <pre><code>import android.support.annotation.Nullable;
  import android.support.v7.app.AppCompatActivity;
  
  public class LoginActivity extends AppCompatActivity {
      @Override
      public void onCreate(@androidx.annotation.Nullable @Nullable Bundle savedInstanceState, @androidx.annotation.Nullable @Nullable PersistableBundle persistentState) {
          super.onCreate(savedInstanceState, persistentState);
      }
  }
  </code></pre>
  <p>Is there some IDE setting to remove auto generation of <code>androidx.annotation</code>?</p>
  <h3>Update</h3>
  <p>I could get rid of this problem with migrating to <code>androidx</code> (<a href="https://developer.android.com/topic/libraries/support-library/refactor" rel="noreferrer">from official doc</a>), but I am not able to migrate all projects to <code>androidx</code> currently. So need a solution.</p>
