Adobe stopped ALL development of Flash for Android last year.
http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html there are older versions of Flash Player (for Android) at that link, but there are no guarantees any of them will work.
Check Android forums for alternatives.

I've read a lot about "Dolphin" for Android https://play.google.com/store/apps/details?id=mobi.mgeek.TunnyBrowser
I'm not an Android user (no tablet or phone) so I can't make any endorsements that would hold any credibility, but most of the Flash solutions I've read point to Dolphin as the best alternative.
Again, check Android forums: http://androidforums.com/ to see what their "gurus" recommend.
