I've made a fresh eclipse reinstall + Android SDK v4.0. I am trying to create a new 4.0 AVD and getting this error: [2011-10-21 11:36:38 - SDK Manager] Unable to find a 'userdata.img' file for ABI armeabi to copy into the AVD folder.
Reading How to create an AVD for Android 4.0, I checked SDK manager and I have 'ARM EABI v7a System Image' installed. to be on the save side I un-installed and reinstalled it.
I also copied 'C:\Program Files\Android\android-sdk\platforms\android-13\images' into 'C:\Program Files\Android\android-sdk\platforms\android-14'
Still getting the same error. I have no problems creating 2.1 AVD.
Note: I'm running Win XP
Issue fixed itself after restarting the PC.
