title: Android WebView is not showing content for some URLs
body: <p>I created webView and i want to load some website inside it.</p>
  
  <pre><code>public class MainActivity extends AppCompatActivity {
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
  
      String url = "http://example.com";
      WebView webview=(WebView)findViewById(R.id.myWebView);
      webview.getSettings().setJavaScriptEnabled(true);
  
      webview.loadUrl(url);
  
  
  }}
  </code></pre>
  
  <p>When i set url to be any website - it is working. But for some websites that use frameworks such as Framework7 or ionic - webview is empty.</p>
  
  <p>What should I do?</p>
