title: onResume() WebView not working
body: <p>this is my first question here, I hope I'm not asking something repeated.</p>
  
  <p>I'm making an Android app that consist in just a WebView. The problem is that onResume() doesn't load my web again. I have some external links that open other apps (the browser, the Twitter app, etc) and when I want to go back to my app it shows the background from the LinearLayout and it doesn't loads the WebView. I have the same problem when I lock the screen, it shows a blank screen (my background actually) after unlock. </p>
  
  <p>It's my first time with Android so I can't figure how it all works, here is my code for onPause():</p>
  
  <pre><code>@Override
  public void onPause() {
      myWebView.setVisibility(WebView.GONE);
      myWebView.destroy();
      super.onPause();
  }
  </code></pre>
  
  <p>And this is the code for onCreate(), I don't know if something else is relevant for this problem:</p>
  
  <pre><code>WebView myWebView;
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
  
      //Remove title bar
      this.requestWindowFeature(Window.FEATURE_NO_TITLE);
  
      this.setContentView(R.layout.activity_main);
      super.onCreate(savedInstanceState);
      if (!DetectConnection.checkInternetConnection(this)) {
          Toast.makeText(getApplicationContext(), "No conn message", Toast.LENGTH_LONG).show();        
  
  
      myWebView = (WebView) findViewById(R.id.webView);
          myWebView.setBackgroundColor(0);        
          myWebView.setBackgroundResource(R.drawable.background_wv);
          myWebView.getSettings().setBuiltInZoomControls(true);
          myWebView.getSettings().setSupportZoom(true);
          myWebView.getSettings().setUseWideViewPort(true);
          myWebView.setScrollBarStyle(WebView.SCROLLBARS_INSIDE_OVERLAY);
      } else {
          myWebView.loadUrl(myURL);
          WebSettings webSettings = myWebView.getSettings();
          webSettings.setJavaScriptEnabled(true);
          myWebView.addJavascriptInterface(new WebAppInterface(this), "Android");
          myWebView.setWebViewClient(new MyWebViewClient());
      }
  }
  </code></pre>
  
  <p>Thank you!</p>
  
  <p>PS: I have no onResume code.</p>
