When specifying 'Run emulator' with OS version given like 4.0.3, the plugin correctly detects and installs missing images, i.e.:

$ /dev/shm/cp_hudson/tools/android-sdk/tools/android list target
[android] The configured Android platform needs to be installed: android-15
$ /dev/shm/cp_hudson/tools/android-sdk/tools/android list target
$ /dev/shm/cp_hudson/tools/android-sdk/tools/android list target
[android] Installing the 'android-15,sysimg-15' SDK component(s)...
$ /dev/shm/cp_hudson/tools/android-sdk/tools/android update sdk -u -a -t android-15,sysimg-15
...

$ /dev/shm/cp_hudson/tools/android-sdk/platform-tools/adb start-server

However, when OS is given like 'android-19', it doesn't seem to perform this check:

$ /dev/shm/cp_hudson/tools/android-sdk/tools/android list target
[android] Using Android SDK: /dev/shm/cp_hudson/tools/android-sdk
[android] Creating Android AVD: /dev/shm/cp_hudson/workspace/project/.android/avd/hudson_en-US_160_HVGA_android-19_armeabi-v7a.avd

Error: Invalid --abi armeabi-v7a for the selected target.
[android] Could not create Android emulator: Failed to run AVD creation command

It also doesn't help to provide OS version as 4.4.2:

$ /dev/shm/cp_hudson/tools/android-sdk/tools/android list target
[android] The configured Android platform needs to be installed: 4.4.2
[android] Using Android SDK: /dev/shm/cp_hudson/tools/android-sdk
