Changing to JWPlayer 8 not playing videos in android webview

For playing videos in a website we were using JWPlayer 6 library [http://jwpsrv.com/library/.....js]. After Changing to JWPlayer 8 free version [http://content.jwplatform.com/libraries/Q3PcoYac.js] videos are playing well in website. Based on that website we have an Android app. But the Android app WebView is not playing those videos after changing to JWPlayer 8.
