title: Playing an app local video (.mp4) in a webview
body: <p>I have an app that I'm writing for both iOS and Android. I have a content page with which I need to link to/play a .mp4 video in a UIWebView/WebView. The video is going to be included in the app so that it can work offline.</p>
  
  <p>With iOS I just used a video tag (with source to a project file) and then used NSNotifications to fullscreen and landscape the video (app normally runs in portrait mode). Job done.</p>
  
  <p>On Android I'm having some issues. </p>
  
  <p>Firstly, when you use a local image as the video poster it crashed the app (apparently a known bug - using a remote image solves the problem - although not much help for an offline mode).</p>
  
  <p>Secondly it doesn't play. I've tried both a remote and local file (referenced as file:///android_asset/html/video.mp4).</p>
  
  <p>I've tested the .mp4 from the android browser and it plays okay so I know that the video is fine.</p>
  
  <p>I've tried a different tack using a link to a video instead. I found an example at the following link (have to use google cache to view): <a href="http://webcache.googleusercontent.com/search?q=cache:EVz7nwc8718J:www.codelark.com/2010/05/12/android-viewing-video-from-embedded-webview/+http://www.codelark.com/2010/05/12/android-viewing-video-from-embedded-webview/&amp;cd=1&amp;hl=en&amp;ct=clnk&amp;gl=uk" rel="noreferrer">http://webcache.googleusercontent.com/search?q=cache:EVz7nwc8718J:www.codelark.com/2010/05/12/android-viewing-video-from-embedded-webview/+http://www.codelark.com/2010/05/12/android-viewing-video-from-embedded-webview/&amp;cd=1&amp;hl=en&amp;ct=clnk&amp;gl=uk</a></p>
  
  <p>My code is as follows:</p>
  
  <pre><code>webengine = (WebView) findViewById(R.id.webview);
  webengine.getSettings().setJavaScriptEnabled(true);
  webengine.getSettings().setPluginsEnabled(true); 
  webengine.getSettings().setAllowFileAccess(true);
  webengine.setDownloadListener(new DownloadListener()
  {
      public void onDownloadStart(String url, String userAgent, String contentDisposition, String mimeType, long size)
      {
          Intent viewIntent = new Intent(Intent.ACTION_VIEW);
          viewIntent.setDataAndType(Uri.parse(url), mimeType);     
      try
      {
           startActivity(viewIntent);
      }
      catch (ActivityNotFoundException ex)
      {
           Log.w("sta", "Couldn't find activity to view mimetype: " + mimeType);
      }
  }
  
  });
  webengine.loadUrl("file:///android_asset/html/index.html"); 
  </code></pre>
  
  <p>With a remote video link it tries to open the android browser and then bails back to the app. With a local video link it appears to load the player but I get "Cannot play video - Sorry, this video cannot be played"</p>
  
  <p>This is my logcat log:</p>

  <p>I've also tried the above approach in shouldOverrideUrlLoading which has the same result.</p>
  
  <p>Thanks</p>
