android - externen Link in der Webview App öffnen

Question

Wenn ich einen externen Link von Browser/Mail anklicke, öffnet sich meine Webview-App (diese Arbeit).

..und jetzt das Problem: Wenn die App geschlossen ist, wird die Verknüpfung korrekt geöffnet. Wenn die App bereits geöffnet ist, wird die Verknüpfung nicht geöffnet.

Ich dachte an das Fixieren mit "shouldOverrideUrlLoading", aber die Funktion wird nie aufgerufen.

---- Startcode ----

public class MainActivity erstreckt Aktivität {

private WebView mWebView; 
private Bundle savedInstanceState; 

/** 
* Dichiariamo l'attributo di classe url in cui 
* salviamo l'indirizzo web che aprirà la webview 
*/ 
private String url = "https://asp-center.fgp.biz?app=1&id="; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 


    Intent intent = getIntent(); 
    String action = intent.getAction(); 
    String type = intent.getType(); 

    if (savedInstanceState != null && intent.getData() != null) { 
     mWebView.restoreState(savedInstanceState); 
    } 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    //carichiamo la webview dentro il layout specificato 
    mWebView = (WebView) findViewById(R.id.webView1); 
    mWebView.getSettings().setJavaScriptEnabled(true); 
    mWebView.getSettings().setLoadsImagesAutomatically(true); 
    mWebView.getSettings().setDomStorageEnabled(true); 
    mWebView.getSettings().setBuiltInZoomControls(true); 

     //permette di gestire i _blank 
    mWebView.getSettings().setSupportMultipleWindows(false); 
    mWebView.setWebChromeClient(new WebChromeClient() { 
     @Override 
     public boolean onCreateWindow(WebView view, boolean isDialog, boolean isUserGesture, Message resultMsg) { 
      WebView.HitTestResult result = view.getHitTestResult(); 
      String data = result.getExtra(); 
      Log.d("DATA", "" + data); 
      // view.loadUrl(data); 

      WebView newWebView = new WebView(view.getContext()); 
      WebView.WebViewTransport transport = (WebView.WebViewTransport) resultMsg.obj; 
      transport.setWebView(view); 
      resultMsg.sendToTarget(); 
      return true; 
     } 

    }); 

    mWebView.requestFocusFromTouch(); 

    mWebView.setWebViewClient(new WebViewClient()); 
    mWebView.setWebChromeClient(new WebChromeClient()); 


    // prendo l'id del dispositivo che mi aiuta a controllare se è attivo l'auto-accesso (non sono richieste credenziali) per il suddetto dispositivo 
    String android_id = Secure.getString(this.getContentResolver(), Secure.ANDROID_ID); 

    //scrivo del testo di debug 
    TextView t = (TextView)findViewById(R.id.textView);

    //imposto la url di default per l'apertura della app 
    String url = "http://fgp.intranet/ggweb/gol_home_mobile.php?app=1&id_device=" + android_id; 

    //controllo se l'apertura della app è stata fatta da un link esterno (come le mail di notifica richieste) 
    if(intent.getData() != null) { 

     //se è stata aperta esternamente, apro il link passato 
     url = intent.getData().toString(); 
     t.setText(url); 
     //url2 = intent.getData().toString(); 

    } else { 



    } 

    //carichiamo la url nella webview 
    mWebView.loadUrl(url);

Sie nee die in onNewIntent zu behandeln. On create wird nie wieder aufgerufen, wenn die Aktivität bereits geöffnet ist.

@Override 
protected void onNewIntent(final Intent intent) { 
    super.onNewIntent(intent); 

    if (intent == null) { 
     return; 
    }else{ 
     // Your code to handle intent 
    } 
}
