SWF, the contraction of Shockwave Flash, is a vector graphics file format created by Macromedia and that was very popular on the Internet to display multimedia contents. Although it has been gradually replaced by HTML5, capable of embedding those contents into the web's code, there are still many pages that still show presentations developed in Flash.
How to play Flash files on Android?
Well, to be able to view any of these contents on a smartphone or tablet, you're going to need the APK of the player initially developed by Macromedia and distributed by Adobe Systems. We're obviously talking about Adobe Flash Player.
The player for the fomat that became a standard back then.
This player will allow you to play these files both on and offline because, although less often than before, you probably still receive quite a few emails with attachments in SWF format. And, as you can imagine, if you can open that same file on different devices and operating systems, that's because Flash Player works like a virtual machine.
Which version is the best to download?
Obviously the latest and most updated version. If not, you run the risk of seeing all those typical empty boxes when you browse the web and that prevents you from seeing all those typical blank boxes when browsing the web that prevents you from watching videos or animations.
However, you should know that there are no longer any updates after version 11 and there's no support for Android versions after Ice Cream Sandwich 4.0. Therefore, if you use a modern phone with Lollipop, KitKat or subsequent systems, you might have a few problems in hand.
The downfall of Flash
SWF was back then, as we said before, a very popular format that managed to become a standard: it was necessary to be able to watch any video. The thing is that HTML5 is more practical since it allows developers to integrate multimedia content into the website's own code.
Despite still being used, it will end up disappearing.
In turn, over the last few years, it has also featured many security problems. This led web browsers of the likes of Google Chrome or Mozilla Firefox to stop supporting it by default, putting a nail in the coffin of this format that will soon disappear from the web.
