When God closes a door, he opens a window for you. Since the door is closed for Flash on Jelly Bean, is there any window left? The answer is yes. You can still view rich media content on Jelly Bean devices. Here’s how to install Adobe Flash on Nexus 7 or other Jelly Bean devices.
Adobe’s Flash Player isn’t officially supported in the newest Android version, 4.1 Jelly Bean. Though the default browser for the Nexus 7 and other Jelly Bean devices is now Chrome, which has built-in Flash support in the desktop versions, this does not apply to mobile devices.
Adobe warned that attempts to install Flash on Jelly Bean devices wouldn’t work, but it looks like the folks at XDA developers found a way to do just that.
On devices that upgraded to Jelly Bean, such as the Galaxy Nexus, the stock “Browser” app still exists. Users can sideload the Flash APK and enable it via the browser’s settings, then enjoy surfing and viewing media as before.
Devices that come with Jelly Bean pre-installed — Like the Nexus 7 — no longer have the Browser app, just Chrome. And mobile Chrome won’t hook up with Flash even if it’s installed. No problem, because there’s a way to install the Browser app from previous Android versions. That, coupled with sideloading Flash, will get you back to normal.
Since Flash isn’t supported on 4.1 there might be some stability and speed issues. But this is a decent stop-gap measure until the entire web gets HTML5-ified.
