It seems that Apple sticking it out and refusing to allow Flash on their devices has led to Adobe dropping the development of the software on mobile devices altogether.
Adobe Flash will no longer be available from the Android’s Google Play Store after today, so if you need it for any particular reason, I suggest you go and download it now, as this is your last chance. Of course, it will then become unsupported and no updates will be available making it rather unsecure, so its recommended to download if you only need it for a development of some sort and know what you are doing when it comes to technology.
The support will continue for PC users, so don’t worry, however with HTML5 coming readily into the mix, Flash is seeing less use due to it’s file sizes in comparison and sometimes speed too. Also, Flash tends to crash a lot requiring a browser refresh or sometimes a PC restart if you were in a full screen mode. HTML5 seems to never crash.
The reason Adobe has given for the removal is that the latest version of Android called Jelly Bean will cause “unpredictable behaviour” within the software, probably due to some usage of HTML5 causing conflicts.
Your existing versions on your phone will be updated and have bug fixed available right up to September 2013, however after that time the software will then become unsupported by Adobe, so it will become a security risk. By then, we can expect to see a lot more use of HTML5 anyway.
The best thing for Adobe to do is to invest their profits into HTML 5 and make their money that way, as Flash is sadly going to die out on the computers too within the next couple of years unless it can be optimized in some way for gaming or 3D technology within the browser, which are its only solutions left.
