On Build Tools 25.3.0 Google removed the command "android" which throws out
The android command is no longer available. For manual SDK and AVD management, please use Android Studio. For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager
so "android create avd" doesnt work anymore. The plugin seems to be using it to create the emulators. Every build fails with
"Could not create Android emulator: Failed to parse AVD config file"
