The use of Thread class bothers me calling the WebView from the run function will lead to an exception as the WebView is created and used in another thread. I would perform this with an AsyncTask. In this example, I use an AsyncTask to load an error file into the WebView if the timeout was reached. If the page loads properly I cancel the AsyncTask. The onPostExecute runs in the UI thread so there is no thread safety problem to interact with the WebView:

private class CustomWebViewClient extends WebViewClient {
    boolean mPageLoaded;
    final int mTimeoutLength = 20000;
    WebView mView;
    TimeoutCheck timeoutCheckTask;

    public CustomWebViewClient()
    {
        super();
        mPageLoaded = false;
    }

    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        mView = view;

        timeoutCheckTask  = new TimeoutCheck();
        timeoutCheckTask.execute(null,null);
    }

    public void onPageFinished(WebView view, String url) {
        mPageLoaded = true;
        timeoutCheckTask.cancel(true);
    }

    private class TimeoutCheck extends AsyncTask {
        protected Void doInBackground(Void... params) {
            long count = 0;
            while (count < mTimeoutLength)
            {
                try
                {
                    Thread.sleep( 1000 );
                }
                catch ( InterruptedException e )
                {
                    e.printStackTrace();
                }

                // Escape early if cancel() is called
                if (isCancelled()) break;
                count += 1000;
            }
            return null;
        }

        protected void onPostExecute(Void result) {
            if(!mPageLoaded) {
                mbLoadedErrFile = true;
                //load error file into the webview
                mView.loadUrl("file:///android_asset/url_err_timeout.html");
            }
        }
    }
