how can i download adobe flash in my ipad 3

There is no version of Flash Player for the iOS system of tablets and phones nor for the most recent Andriod OS tablets and phones as Adobe is not updating the software to be compatible with newer systems. By the time Apple has upgraded the iOS to version L and Android has been updated to Chocolate Covered Ants the need for Flash on tablets will be gone. Until then, the best workaround is to allow your iPad to remote control a PC and run Flash Player remotely. There is no lack of remote PC applications.

1. This is the Adobe Reader forum
2. Apple has banned Flash Player from iOS
