Lately, more and more people have complained about the security of the Adobe app, because the developers didn’t manage to fix all vulnerabilities that could be used by hackers to gain access to targeted devices that have the Flash app installed on them. The company has released many updates to reduce some of the vulnerabilities and recently a beta for Flash Player 21 and AIR 21 brought “new features as well as enhancements and bug fixes related to security, stability, performance, and device compatibility”.



AIR 21, which was codenamed Sutter, allows developers to package the same code into native applications and games and this Flash-enabled content integrated into applications have reached 500 million mobile devices and 1 billion PCs. A few days ago, Adobe Labs has released the AIR 21 SDK & Compiler beta archives for Apple’s Macs and Windows devices, which can be downloaded from the company’s official website.

The developers who will download the beta of the AIR SDK & Compiler will be able to distribute and test captive runtime versions of their AIR applications, then publish them on the Google Play, Apple’s iOS store or Amazon. The developers are advised to update their applications with the GM build, whenever it’s available.

Adobe AIR 21 Beta brings a new feature named Flash Player Anonymous Usage Data, which works only with beta versions of Flash Player and it shows a check box option for “Usage Data”, where the users will have the choice to receive or not information provided by this feature. The customers can find data saved to a plain text file and they can review it any time. If they uninstall Flash Player, this service and all log files will disappear as well. Android StageWebView debugging is another important addition to AIR 21, as it allows developers to debug web content from AIR Android applications.

The issues that have been fixed:

– in iOS, AIR failed to link ImageIO.framework when targeting iOS;
– in Android, GPU mode apps crashed on devices with Tegra K1 GPU;
– in Android 6 Marshmallow, Stage3D AIR application was failing to return from background;
– ATF textures (with JPEG Compression) were not rendered properly on MALI GPU;
– on desktop, AIR Apps created from Version 20 SDK was not accepted in MAC App store.
