WebView - onReceivedHttpAuthRequestは決して止まらない

Question

私はAndroid webviewアプリケーションでデッドループに陥り、アプリケーションはonReceivedHttpAuthRequest関数でブロックされます。活動に

mWeb.setWebViewClient(new WebViewClient() { 
    @Override 
    public void onPageFinished(WebView view, String url) { 
     mProgressBar.setVisibility(View.GONE); 
    } 

    @Override 
    public void onReceivedHttpAuthRequest(WebView view,HttpAuthHandler handler, String host, String realm) { 
      if (isAdded()) 
       handler.proceed(getResources().getString(R.string.username), getResources().getString(R.string.pass)); 
    } 

    @Override 
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) { 
     handler.proceed(); 
    } 
}); 
mWeb.loadUrl(mUrl); 

Answer 1

    mWebView.LoadUrl(url); 
    await Task.Delay(10000);        
    if (!mWebView.IsShown | cliente.ErroReportado) 
    { 
     Toast t = Toast.MakeText(Android.App.Application.Context, "Erro ao acessar o servidor, verifique conexão, usuário e senha e tente novamente!", ToastLength.Long); 
     t.SetGravity(GravityFlags.Center, 0, 0); 
     t.Show(); 
     OnCreate(null); 
    } 
    } 

WebViewClientで

 

     class ViewClient : WebViewClient 
     { 
      MainActivity _activity; 

      public int iTentativasLogin { get; private set; } 
      public bool ErroReportado { get; private set; } 


      public ViewClient(MainActivity activity) 
      { 
       _activity = activity; 
      } 


      public override void OnReceivedHttpAuthRequest(WebView view, HttpAuthHandler handler, string host, string realm) 
      { 
       Toast t ; 
       if (Usuario.Length == 0 | Senha.Length == 0) 
       { 
        t = Toast.MakeText(Android.App.Application.Context, "Usuário ou senha não preenchidos", ToastLength.Long); 
        t.SetGravity(GravityFlags.Center, 0, 0); 
        t.Show(); 
        handler.Cancel(); 
        ErroReportado = true; 
       } 
       else 
       { 
        iTentativasLogin++; 

        if (iTentativasLogin < 4) 
        { 
         handler.Proceed(Usuario, Senha); 
        } 
        else 
        { 
         t = Toast.MakeText(Android.App.Application.Context, "Usuário ou senha incorretos", ToastLength.Long); 
         t.SetGravity(GravityFlags.Center, 0, 0); 
         t.Show(); 
         handler.Cancel(); 
         ErroReportado = true; 
        } 

       } 
    } 
}
