通过android webview iframe连接到gmail / facebook帐户导致崩溃

Question

因为我想通过我的Android应用程序上的iframe连接到Facebook。当我尝试输入用户名和密码时发生崩溃。特别是当我第一次输入用户名或密码时，我可以输入数据，但是当我从用户名字段切换到密码字段时，反之亦然，我遇到了崩溃。

此崩溃仅针对android lolipop

崩溃日志只说这个：

12-17 14:52:04.242  A/chromium﹕ [FATAL:jni_android.cc(271)] Check failed: false. 
12-17 14:52:04.243  A/libc﹕ Fatal signal 6 (SIGABRT),code -6 in tid 28156

为facebook / gmail连接设置android webview iframe的代码是：

public static void show(Activity mainActivity, Context mainContext, WebViewClient client, IframeAgentInterface javascriptInterface, String javascriptInterfacename,String url,int width, int height)
{   
        boolean isLocalFile = false;

        Point screenSize = new Point();
        if(width == -1 || height == -1) {
            mainActivity.getWindowManager().getDefaultDisplay().getSize(screenSize);
        }

        if(width == -1){
            width = screenSize.x - 150;
        }
        if(height == -1){
            height = screenSize.y - 150;
        }

        MobileIframeWebView.width = width;
        MobileIframeWebView.height = height;
        MobileIframeWebView.activity = mainActivity;

        MobileIframeWebView.context = mainContext;
        MobileIframeWebView.parentView = (AppFwkWebView)(MobileIframeWebView.activity.findViewById(R.id.sasappview));
        MobileIframeWebView.client = client;

        if (url.startsWith(PREFIX_WEB_URL_HTTP))
            MobileIframeWebView.url = url;
        else {

            isLocalFile = true;
            MobileIframeWebView.url = FileHelper.GetLocalFileURL(url);

            // check if file exists
            if (!FileHelper.DoesFileExist(url))
                return;

            // now check if the file needs to be opened in a browser, that is
            // if the webview cannot open it
            if (FileHelper.IsWebViewFileType(MobileIframeWebView.url)) {

                startBrowserActivity(mainActivity, mainContext, MobileIframeWebView.url);
                return;
            }
        }

        MobileIframeWebView.javascriptInterface = javascriptInterface;
        MobileIframeWebView.javascriptInterfaceName = javascriptInterfacename;
        mainActivity.runOnUiThread(new Runnable() {
            public void run() {
                LayoutInflater inflater =LayoutInflater.from(MobileIframeWebView.context);
                LinearLayout iframeLayout = (LinearLayout) inflater.inflate(R.layout.iframe_skeleton, null,false);

                iframeLayout.setLayoutParams(new LinearLayout.LayoutParams(MobileIframeWebView.width,MobileIframeWebView.height));

                MobileIframeWebView.popup = new PopupWindow(
                        iframeLayout,
                        MobileIframeWebView.width,
                        MobileIframeWebView.height,
                        true);

                //show the iframe
                MobileIframeWebView.openedIframe = (MobileIframeWebView) (iframeLayout.findViewById(R.id.view_iframe));
                View emptySpace = (View) (iframeLayout.findViewById(R.id.empty_space_close_iframe));
                ImageView closewv = (ImageView) (iframeLayout.findViewById(R.id.close_iframe));

                int emptySpaceWidth = MobileIframeWebView.width - closewv.getLayoutParams().width;
                if(emptySpaceWidth > 0)
                    emptySpace.getLayoutParams().width =  emptySpaceWidth;

                MobileIframeWebView.openedIframe.getSettings().setJavaScriptEnabled(true);
                MobileIframeWebView.openedIframe.requestFocus(View.FOCUS_DOWN);

                MobileIframeWebView.openedIframe.setWebViewClient(MobileIframeWebView.client);
                MobileIframeWebView.openedIframe.setWebChromeClient(new WebChromeClient());
                if(MobileIframeWebView.javascriptInterface != null)
                    MobileIframeWebView.openedIframe.addJavascriptInterface(MobileIframeWebView.javascriptInterface, MobileIframeWebView.javascriptInterfaceName);

                MobileIframeWebView.openedIframe.loadUrl(MobileIframeWebView.url);

                closewv.setOnTouchListener(new MobileIframeOnTouchListener(MobileIframeWebView.openedIframe));

                MobileIframeWebView.popup.showAtLocation(MobileIframeWebView.activity.findViewById(R.id.frameLayout1), Gravity.CENTER, 0, 0);
