body: <p>I have Activity layout:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      tools:context=".MainActivity"&gt;
  
      &lt;WebView
          android:id="@+id/webView"
          android:layout_width="300dp"
          android:layout_height="300dp"
          android:layout_marginTop="8dp"
          android:clickable="false"
          android:layerType="software"
          app:layout_constraintBottom_toBottomOf="parent"
          app:layout_constraintEnd_toEndOf="parent"
          app:layout_constraintStart_toStartOf="parent"
          app:layout_constraintTop_toTopOf="parent"/&gt;
  
  &lt;/android.support.constraint.ConstraintLayout&gt;
  </code></pre>
  
  <p>And activity</p>
  
  <pre><code>public class MainActivity extends AppCompatActivity {
  
      @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          WebView webView = findViewById(R.id.webView);
          webView.setBackgroundColor(0x00000000);
          webView.loadUrl("http://gifok.net/images/2018/05/10/1212.gif");
      }
  }
  </code></pre>
  
  <p>When I start this app on emulator - I see animated GIF But When I start this app on my Device - I see static image without animate. Why?</p>
