I am trying to build and run an android project using the phonegap framework.
I have configured the IDE and followed the steps described in an official tutorial (see link above).
The problem is that I never had a chance to build the project since it contains errors. The major one is (see screenshots):
Archive for required library: 'C:/Program Files/Android/android-sdk/platforms/android-8/android.jar' in project 'xxx' cannot be read or is not a valid ZIP file

Also, I have tried to manually run the aforementioned android.jar but got the same error:

The problem keeps reproducing through several SDK versions: r14, r15.
BTW, I experience no troubles building a project using other android versions, e.g., 2.3.
Would someone help me out? Thanks!
Use the Android package manager to remove and then re-download the Android 2.2 SDK as something is corrupt with that package.
