How to downgrade Android ADT?
I also made the mistake of upgrading to the latest ADT. Heres a quick way to get your old one back.
- Head over to http://developer.android.com/sdk/eclipse-adt.html#notes and pick which pick which version you want to use again.
- Create your download url: http://dl.google.com/android/ADT-##.#.#.zip. Google uses the version number for the downloads, so if you need 10.0.1, your download would be http://dl.google.com/android/ADT-10.0.1.zip.
- Uninstall the current ADT version in Eclipse.
- Install the new version as an archive!
