I get a null pointer exception opening about half of the android XML files in my layout directory. There seems to be no pattern to why some files open and some files don’t.
I upgraded eclipse to Juno. Re-installed all the plugins (ADT), re-installed the android SDK. I brought in my old workspace and adjusted my projects to point at the new android SDK.

I found one way to resolve this. My eclipse recently crashed (and wouldn’t start again) for an unrelated reason. To get it to start again I deleted most of the files in ${workspace}/.metadata/.plugins. These files regenerate (but will wipe some of your saved plugins and settings). Resolved my startup problem and my xml editor problem.
