I too have ran into this same issue. I literally selected update from the Eclipse (3.5.1) menu and allowed the IDE to download and install the ADT 0.9.9 update and poof my development environment was FUBAR. I appreciate the work that goes into patches and updates but all of that takes a back seat when the installation process itself breaks the user's environment.
As I suggested in my note to the author most of us supporting this platform are busy developers with more going on than just Android. I can't afford to lose a day because the installer for a minor update blew up my development environment. Its just not acceptable and neither is the answer reinstall your dev environment, though that is what I've ultimately had to do. I'm really impressed with how far Android has come in such a short time. Both the OS and the development tools. But I have to say its times like this that I can appreciate Apple and Microsoft's model (shudder). Not that they don't ever break things with releases, we all do. But when something goes wrong using Visual Studio for example there is a very defined process for getting a resolution. It seems to me someone at Google should have tried to duplicate this issue and posted the status of that testing and hopefully provided the community a work around. Even if that work around is to pull the ADT update until a fix is in place to prevent other users from accidentally rendering their environment inoperable. Everyone who is reporting the problem seems to have the same set up. The key seems to be users who went from 0.9.7 to 0.9.9 without installing 0.9.8. Can we get some feedback from Google as to whether this testing has been done yet and whether the testing yielded the same results? And how those of us who are at 0.9.7 on a machine update to 0.9.9 without doing a complete reinstall? Any help is appreciated. I hate to think I will have to reinstall the dev environment on my other two machines. Or I guess I could just not update the ADT on them. But I suspect following that route, I'll just compound the issue when there is an ADT update I really can't live without. Anybody got any thoughts?
