应该没有在三星Galaxy和HTC设备上调用

Question

我正在做这样的事情：

LoadDataWithBaseURL("file:///android_asset/adhese/",fileContent, "text/html", "UTF-8", null); 

我的Webview客户类：

public class DataWebViewClient : WebViewClient
{
    public delegate void PageLoaded();
    public event PageLoaded PageLoadedEvent;
    public AndroidAdController controller;

    public override bool ShouldOverrideUrlLoading (WebView view, string url)
    {
        if(url.Contains ("addsResponseLoaded"))
        {
            view.EvaluateJavascript ("window.giveMeMyResponse();", controller.JSResultObj);
            //view.StopLoading ();
            return false;
        }
        return true;
    }

    public override void OnPageStarted (WebView view, string url, Android.Graphics.Bitmap favicon)
    {
        if (!url.Contains ("addsResponseLoaded"))
            base.OnPageStarted (view, url, favicon);
        else
            view.StopLoading ();
    }

}

javascript函数：

 function giveMeMyResponse(){
        // send the ads object and the response object to the native app as json
        return "[{\"myAds\":"+JSON.stringify(ads)+",\"myResponse\":"+JSON.stringify(myResponse)+"}]";
    }
    ads.response.then(function (response) {
        // send a signal to the native app the adds have succesfully loaded by changing the url to addsResponseLoaded
        myAds = ads;
        myResponse = response;
       this.document.location.href = "addsResponseLoaded";
    });

在某些设备上，例如oneplus，可以调用onpagestarted，然后调用overrideurlloading。

但是在htc或samsung galaxy等其他设备上，永远不会调用shouldoverrideurlloading方法。我应该怎么处理这个？
