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.
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.
On Android I'm having some issues.
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).
Secondly it doesn't play. I've tried both a remote and local file (referenced as file:///android_asset/html/video.mp4).
I've tested the .mp4 from the android browser and it plays okay so I know that the video is fine.
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): 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/&cd=1&hl=en&ct=clnk&gl=uk
My code is as follows:
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");
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"
This is my logcat log:

I've also tried the above approach in shouldOverrideUrlLoading which has the same result.
Thanks
I was stuck in a similar problem. Finalyl I got the thing working by using "video" HTML5 tag
- There is something in android OS that prevent opening the video from assets. I had to copy the html and video to SDCard. You can then use the sdcard path instead of assets path.
- Dont forget to use android:hardwareAcceletrated = "true" for your webview activity
