Any Windows Pro tablet can use Flash Player not in Metro mode but in standard desktop mode. Also some of the older Android tablets use Flash Player. I'm not sure about anything after Android 4.1 though . I think 4.0 and below is good for you.
Flash Player for Android is no longer available. For more information, see here:
Android users can still download and install Flash Player from the Archived Flash Player Versions page on the Adobe website.
