Adobe has removed support to all new Andriod platforms and will no longer support installing it on older hardware that doesn't already have it installed. Adobe announced a while back that they were no longer going to support Flash Player on the mobile platforms.
I have read a little about that but according to Adobe's certified devices page there are devices running the same OS, Android 4.0, that the galaxy tab 2 is running which are certified to run Flash Player such as the Acer Iconica Tab A100 and the Toshiba Excite10 AT300. The samsung Galaxy Tab 2 isnt on the certified list but Adobe adds on the same page that installation on an uncertified device may result in unexpected behaviour which implies that it is still able to be installed but it may stuff up the device. I just dont understand why the Galaxy Tab 2 doesnt give you the option to even try and get it to work. Im fighting a battle that is already lost here i know but its just frustrating because now i cant use my tablet for what i wanted it for. I just wish there was another program that would do the same function. Thanks for your help
