I\'m piecing together a cheapo app that amongst other things \"frames\" some of our websites... Pretty simple with the WebViewClient. until I hit the video.
WebViewClient
I had a similar problem. I had HTML files and videos in the assets-folder of my app.
Therefore the videos were located inside of the APK. Because the APK is really a ZIP-file, the WebView was not able to read the video-files.
Copying all HTML- and video-files onto the SD-Card worked for me.
