no ABI error , when creating an Android virtual device

I am getting a No ABI error when creating a virtual device. My setup includes

Android SDK

ADT plugin

Eclipse

when I run

 android list targets

it gives me

  Name: Android 4.0.3
  Type: Platform
  API level: 15
  Revision: 2
  Skins: HVGA, QVGA, WQVGA400, WQVGA432, WSVGA, WVGA800 (default), WVGA854, WXGA720,
  WXGA800
 ABIs : no ABIs.

and when I try to run

  android create avd -n myandroid -t 1

it gives

  This platform has more than one ABI. Please specify one using --abi.

how do I specify ABI and hence create an AVD
