I followed the example on the plugin documentation page (https://wiki.jenkins-ci.org/display/JENKINS/Android+Emulator+Plugin) to create a matrix job using the android emulator plugin.

Using x86 as a fixed property and the rest as matrix axes.

These are the os axes defined:

I'm getting an error only when the os is android-MNC. I checked the logs and the create avd command is missing the --abi property. All other matrix combinations are able to create the avd and include the --abi property

The error message for android-MNC runs is:

[android] android-sdk/tools/android create avd -f -a -s WSVGA -n hudson_pt-BR_320_WSVGA_android-MNC_12 -t android-MNC
	There is more than one system image defined for platform 'android-MNC'.
	Pick an image to use and set it in the 'Target ABI' config field.
	Valid ABIs: default/x86, default/x86_64
