So happy to get your Android 4.1 Jelly Bean running Nexus 7 with you now? But one thing for sure you will be disappointed with Android 4.1 since this latest Android version is not supporting Adobe Flash. If you are big fan of Facebook games, I believe you will not be happy with this change made on the latest Android version but still our loving XDA developers always ready with the solution/fix. XDA recognized contributor stempox has just found that by simply side-loading the APK, users are able to view the media content.
Since Nexus 7 does not come with a default browser, you may need to manually install a browser and from here, you will start work on “putting” Adobe Flash in your browser.
How to Install AOSP Browser on Nexus 7:
1. Download browser apk.
2. Use ES file explorer with root permissions (your device must be rooted).
3. Place browser apk in /system/app folder, change the permission to rw-r—r— from rw———
4. You will be seeing a browser provider.apk and browser provider.odex, rename both file (you could simply add one character after the file extensions)
5. Then reboot your device and all done.
After you have added in a browser for your device, then followed up by installing Adobe Flash Player:
