title: how to load pdf file in a webview from assets folder
body: <p>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?). </p>
  
  <pre><code> webView = (WebView) findViewById(R.id.webView1);
      WebSettings settings = webView.getSettings();
      settings.setJavaScriptEnabled(true);
  
  
      if(Build.VERSION.SDK_INT&gt;=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");
  </code></pre>
