title: Activity.setProgress(int progress) is deprecated
body: <p>I would like to show progress bar when android webview is loading and I used Activity.setProgess(int).</p>
  
  <p>Android documentation says setProgress(int progress) was deprecated in API level 24. No longer supported starting in API 21.</p>
  
  <p>So, what should I use instead to show progress when webview is loading?</p>
