My jelly bean phones are not rooted. I was hoping to be able to place a file, or a shortcut to a file, such as a '.pdf' on the homescreen.
I have seen suggestions that it may be done, by using file managers, but maybe that no longer applies. Both devices have 4.2.2 jelly-bean. See for instance this question.
I have tried on an HTC desire 310 and on an Alcatel onetouch. I get no option to add the file or shortcut to the home screen. I did install the Astro file manager, with a shortcut on the home screen but did not see any additional option for putting a pdf on the homescreen.
