Yesterday the autocomplete in Android XML layout files stopped working all of a sudden (I hadn't even updates anything). When I hit Ctrl + space, eclipse says 'content assistant not available at the current location'.
I know this and this answer, but I don't even have the Api Tools Proposals option in my preferences.
I even downloaded the newest ADT bundle, it worked at first, I only imported a couple of projects, then it stopped working again!
What could be wrong?
