i had some similar issues with the support library because of diffrent versions in ABS and in my project (but not using VPI)
try to download the latest android-support-v4.jar with the Android SDK Manager and then copy the jar from <sdkdir>/extras/android/support/v4/android-support-v4.jar
to your project and also to ABS and VPI (afaik both have a older copy of android-support-v4.jar in thier download)
