Open File From URL in Xamarin.Android by ignoring Deep Linking

Question

I am working on a Xamarin.Android application.

I've defined a "Deep Linking", like :".example.com". Everything works fine, but I need a blacklist on a specific folder like ".example.com/media/*" (because in this folder I have only the files/attachments).

<!-- Activities  -->
    <activity android:name="ApplicationLaunchActivity">
        <intent-filter android:autoVerify="true">
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="https" android:host="*.example.com" />
        </intent-filter>
    </activity>

And in LaunchActivity I have

[IntentFilter(new[] { Android.Content.Intent.ActionView },
        AutoVerify = true,
        Categories = new[] 
        {
            Android.Content.Intent.CategoryDefault,
            Android.Content.Intent.CategoryBrowsable
        },
        DataScheme = "https",
        DataPathPrefix = "",
        DataHost = "*.example.com"
        )]

So, as I've read in this post , there is no blacklisting in Deep Linking in IntentFilter. So what I can to do is loading files in a WebView. For image files, I've no problem but for files with pptx or pdf, there is shows nothing in WebView.

WebView postAttachmentsWebView = FindViewById<WebView>(Resource.Id.PostAttachmentsWebView);
postAttachmentsWebView.LoadUrl(url);

Do you have any idea for me? Is there any solution for forcing Android to open this specific URL with WebBrowser on not using DeepLinking? Or other solution? Any suggestions?
