Welcome to Adobe Forums.
You can download Flash Player .apk file (installer file for Andriod) from here : http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html
Once the file is download, move it your Andriod device (using your computer) and then run the installer.
How do I move it from my computer to the andriod. The only connect I make between my Andriod and my computer is to sync contact and pictures.
