在WebView中加载自定义URL

Question

In my app, i am loading "http" url in the webview. This url is loaded correctly, but there are some internal url's loaded with the protocol "sheet://". While loading this url i get an error "protocol isn't supported". Can anyone please help how to fix this? How to load the url's with the protocol "sheet://" ?

PS: I am using shouldOverrideUrlLoading method to load the url.

This is the code I am using

 public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if(url.contains("sheet://")){
          Intent url_intent = new Intent ( Intent.ACTION_VIEW,Uri.parse(url));
          url_intent.addCategory(Intent.CATEGORY_BROWSABLE);
          startActivity(url_intent);
          return false; 
        }else{
              view.loadUrl(url);
              return true; 
        }
 }

Thanks & Regards,

Perhaps host an PHP file, with an header?

<?php
header("Location: sheet://link_to_your_file.extention");
?>

Answer 2

Do you see the call to shouldOverrideUrlLoading come in for your sheet:// URL? That part of the code looks correct (assuming there is an app installed on your device that can handle sheet:// BROWSABLE intents). Or do you mean that the app launched from your app cannot load the sheet:// URL? What app is being launched to respond to the Intent?

One mistake you have is the call to loadUrl when sheet:// is not in the URL. In this case, please just return true . The URL load is already in progress, there is no need to start it again. Doing so infact creates a loop.

您必须在AndroidManifest.xml中使用与该协议匹配的意图过滤器注册活动
