Android: "Error: Invalid --tag default for the selected target."

android create avd -f -a -s HVGA -n hudson_en-US_160_HVGA_android-20_armeabi-v7a -t android-20 --abi android-wear/armeabi-v7a

In case anyone else has the same issue with android-20 (Android 4.4W) turns out the abis are prefixed with android-wear the above should do the trick
