Hi, WebViewer only works with sound, not video. WebViewer with Sound and Video.

To be able to play Youtube videos in the webviewer, you have to edit the manifest and add android:targetSdkVersion="14" or higher. See this thread how to do it.Thank you Boban!

Thank you for replying my post. I just try to do so but doesn't worked. My apps crash after installed. There's 2 files with the name AndroidManifest.xml. In root folder and "original" folder. I can edit file in root folder but couldn't edit file in "original" folder. Do you have other solution?
