Adobe has released statements saying they will no longer support flash for newer Android builds starting with 4.1.
I flashed a custom rom of 4.1 the other day and couldn't find any 3rd party flash support in the market. I use flash for Orb to stream tv. Orb has an Android app but it unusable and all around horrible experience (verified by the the many negative reviews) but you could use the website to stream flash as a work around to the poor app which worked great.
My question is: how can I play flash video in Android Jellybean (4.1)
