how to load pdf file in a webview from assets folder

Question

I ahve a webview in my layout screen. I need to display a PDF file in that webview from my assets folder. I tried below code. While running app displays zoom in and out controls with a blank page(our PDF file is kind of large.is it due to that?).

 webView = (WebView) findViewById(R.id.webView1);
    WebSettings settings = webView.getSettings();
    settings.setJavaScriptEnabled(true);


    if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.JELLY_BEAN) //required for running javascript on android 4.1 or later
    {
    settings.setAllowFileAccessFromFileURLs(true);
    settings.setAllowUniversalAccessFromFileURLs(true);
    }
    settings.setBuiltInZoomControls(true);
    webView.setWebChromeClient(new WebChromeClient());
    webView.loadUrl("file:///android_asset/test.pdf");

I dont want to use external apps to read my PDF. is it possible?then how?
