Today I upgraded to Android SDK 2.3 and I also upgraded the Eclipse Plugin Androi Developer Tools 8.0 (from 0.9.9). I also upgraded my Java Development Kit to 1.6_22.

No

Answer 1

That is rather difficult to answer, given the limited information you have supplied. Here are some suggestions:

• Make sure that an appropriate android.jar is in your build path, since that is where java.lang.Object would come from.

• Do a Project > Clean, to make sure you have 1.6 .class files, in case that is part of the problem.

• Try creating a new project from scratch and see if that works.
