    #
    # Note: Currently (June 2018) there are no arm images for API > 25 provided by google.
    #       This is unlikely to change in the future due to the new emulator supporting
    #       (and requiring!) hardware acceleration for x86.
    #       Unfortunately Travis has no solution yet for providing KVM on the worker machines
    #       so running API25 and up emulators is not possible right now.
