Can not use in Android Nougat

[dovahkrid]

I use YouTube iframe player and another player (plyr - https://github.com/Selz/plyr). But it shows nothing (just a transparent/blank page) on the floating view. The normal webview just works normally.
It has no logs about that so I don't know what happens.
P/s: mintube can not run on Android 7 Nougat
