问题
I am having a problem where when I switch to DDMS view and look at the Logcat, everything is yellow. All lines are yellow and Time, PID, Application, and Tag all display question marks for every line. This makes the Logcat useless and makes it incredibly hard to debug. In the past everything has worked fine and I am not sure why this has started happening.
I am using a Verizon Galaxy Nexus with a 4.1 build (could be the problem?).
I am also a beginner (probably excruciatingly obvious).
Thanks for any help.
SOLVED: Apparently I had to update eclipse and the SDK (i feel dumb). Thanks to everyone who spent time tying to help me out.
(It won't let me answer my own question because i am new)
回答1:
Updating your Eclipse and Android SDK will likely solve the problem.
Here's a screenshot, I have lived this too.

Sounds like you have your filter set to "warn". Make sure that it is set to "verbose" and make that you don't have any other filters on. If you do, on the left you highlight "All Messages" and don't have any other filters set.

See how he has the 'W' selected. Change it to the 'V'

I was struggling with same problem for several days. I have jelly bean on my phone.
Thank you Revolutionair, it seems I got rid of the problem once I did the update for Android SDK, ADT, AVD manager.
