title: Toast.getView() returns null on Android 11 (API 30)
body: <p>I just installed the Android R (API 30) image in my emulator to try my app, and it crashed when trying to set the Background color of a Toast.</p>
  <pre><code>    Toast toast = Toast.makeText(ctxt, msg, duration);
      View view = toast.getView();
      view.setBackgroundColor(0xFF303030);
      TextView tview = view.findViewById(android.R.id.message);
      tview.setTextColor(Color.WHITE);
      toast.show();
  </code></pre>
  <p>This is really strange as in Android Q (API 29) works perfectly.</p>
  <p>My build.gradle updated for Android R (API 30)</p>
  <pre><code>    compileSdkVersion 30
      buildToolsVersion &quot;30.0.1&quot;
  </code></pre>
  <p>Is there a new way to do it??</p>
