The following message is being printed, and the build aborts:
[android] Required Android tools not found in PATH; cannot continue
Version 2.7.1 of the plugin has been released, which includes this fix.
Code changed in jenkins
User: Jørgen P. Tjernø
Don't look for specific emulator binaries.
Only look for the main emulator binary when validating an SDK root -
don't look for the emulator64-* binaries (only in r21+) and the -mips
and -x86 binaries (only in r12+).
This resolves JENKINS-15967.
Potential pull request to fix this: https://github.com/jenkinsci/android-emulator-plugin/pull/19
