Android 4.2 developer settings still unavailable
android, android-4.2-jelly-bean
Solution
I have ran into the same problem yesterday. Only the initial user (or Owner) shows the developer options in the settings menu, when turning on developer mode.
Turn on developer mode for your initial user and you should be able to see the developer options.
I wonder why the secondary user cannot be in developer mode.
EDIT: I am now using the secondary user in developer mode and running my project from Eclipse works just fine!
Problem
How do you access Android 4.2's developer settings when the method prescribed on their developer site does not work? I followed the directions on a Nexus 7 tablet. I went to Settings > About tablet, scrolled to the bottom of the screen, and clicked the Build Number 7 times. I was greeted with the message "Congratulations, you're now a developer." But apparently, I'm still not one. I checked Settings and scrolled all the way down to the bottom, but no Developer options were available. I reset the tablet and restarted it, with no result. When I click on Build Number again, it says "No need, you're already a developer"." UPDATE: Something else that might be an issue. There are two tablet user accounts. The account I'm using to access the developer settings is the second one. The first account is probably not set up as a developer.
