Install Flash on Nexus 7
Just found out that flash is absent from default Chrome browser of Nexus 7 (Android Jelly Bean OS). Too bad, I need to browse quite a number of websites running flash.
On googling, I got great hints (http://www.howtogeek.com/120277/how-to-install-flash-on-the-nexus-7-and-other-jelly-bean-devices/)
First download the flash apk from XDA developer forum (http://forum.xda-developers.com/attachment.php?attachmentid=1199371&d=1342343609)
Second, download and install Firefox-beta from Google Play.
Third, before installation of the flash apk, set the security of Nexus 7 to allow running app from other untrusted sources other than Google Play.
So that's all. Afterward, use Firefox to browse flash websites. One important step is to change back to the original security settings otherwise one will get into trouble of getting malicious applications installed.
