Complient鏈接URL不調用onPageFinished在WebView KitKat 4.4.4

Question

我有一個應用程序，可以在所有Api> 11包括Kitkat 4.4.2上正常工作。

然而，在奇巧4.4.4 onPageFinished（）不燒成1條鏈路：

HREF = 「http://app.host.com/projects/30/edit/」

。

我知道KitKat WebView的問題，並從我知道這個網址應該工作。

與此URL對應的網絡應用程序是用RoR編寫的，並禁用了turbolinks。

我的WebView客戶端如下所示。

我花了好幾天的時間試圖讓這個工作。

如果有人發現任何錯誤，請告訴我。

// Set WebView client 
     mWebAppView.setWebViewClient(new WebViewClient() {

      public boolean shouldOverrideUrlLoading(WebView view, String url) {

         intent = Intent.parseUri(url, Intent.URI_INTENT_SCHEME);

       return super.shouldInterceptRequest(view, url); 

      } 



     });

所以，這是一個醜陋的黑客攻擊，我決定用：

雖然onPageFinished（），onPageStart（）和shouldOverrideUrlLoading（）並不總是由URL的調用，即使格式正確無誤。

我發現shouldInterceptRequest（）被所有無法比擬的url所激發，我試過了（只有有限且不完全科學），它給了我相同的數據來通過url控制流，雖然在頁面加載的早期階段。因此，我使用shouldInterceptRequest（）而不是非常有限的onPageFinished（），onPageStart（）和shouldOverrideUrlLoading（）。

這裏是代碼：

// Set WebView client 
    mWebAppView.setWebViewClient(new WebViewClient() { 
     @Override 
     public boolean shouldOverrideUrlLoading(WebView view, String url) { 

      Log.d(TAG, "#shouldOverrideUrlLoading url called: " + url); 

      // Open an email client on device when openning a mailto: link 
      if (MailTo.isMailTo(url)) { 
       Intent intent = null; 
       try { 
        intent = Intent.parseUri(url, Intent.URI_INTENT_SCHEME); 
       } catch (URISyntaxException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 
       view.getContext().startActivity(intent); 
       return true; 
       // open the help link in a browser. 
      } else if (url 
        .contains("www.host.com/expertise/business-development/index.cfm")) { 
       Log.d(TAG, "should open browser"); 
       startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url))); 
       return true; 
      } else { 
       view.loadUrl(url); 
       return true; 
      } 

     } 

     @SuppressLint("InlinedApi") 
     @Override 
     public void onPageFinished(WebView view, String url) { 
      // super.onPageFinished(view, url); 
      view.clearCache(true); 
      Log.d(TAG, "#onPageFinished loaded page is :" + url); 
      if (pd.isShowing() && pd != null) { 
       pd.dismiss(); 
       Log.d(TAG, "Inside #onPageFinished, pd dismissed"); 
      } 

      // Change orientation for the table screen for phones so that 
      // the tables show correctly 

      if ((url.endsWith("stepfirst/") || url.endsWith("stepsecond/"))&& !isTablet) { 
       setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
      } else if (!isTablet && !url.endsWith("edit/")){ 
       setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
      } 

     } 

     @Override 
     public WebResourceResponse shouldInterceptRequest(WebView view, 
       String url) { 
      // TODO Auto-generated method stub 
      Log.d(TAG, "Inside #shouldInterceptRequest url :" + url); 

      //This is a hack as the "edit" url isn't firing the onPageFinished. 
      if (url.contains("projects") && url.contains("edit")) { 
       setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
      }else if(url.contains("users") || url.endsWith("help/") || url.endsWith("projects/")){ 
       setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 


      } 
      return super.shouldInterceptRequest(view, url); 
     } 
    }); 

是的，它是一個黑客，是的，它限制....而Android強迫我的手。

希望它有幫助。
