BTW
It looks like ITV Player is available for Android Details
HERE
All the players are available for Android. The trouble is, the broadcasters are slow in supporting platforms, and platforms are slow in supporting players, whether TVs, set top boxes (see Freeview), or Android platforms/iOS. Look at the mess with Flash, where first a player was supported on Android but not iOS, then on iOS but not Android, before being supported on both.
The Justop K9 has had a patchy support for players. BBC iPlayer is fine. Some others would play the adverts and then stop. One started fine but then said that the player was not available to play on a TV! Given I bought it to put catch-up on an older bedroom TV, without internet access, it was a big disappointment.
I have a Samsung ES8000 TV and it had all the players on it. I bought the evolution kit to bring it up to this year's specification. The Five player then didn't work for several months.
PS As a case in point, and following your link to the ITV player, it is available for all my devices
except the K9. However, as I said above, even being available does not guarantee that it will run.
