# Invensense uses the OS version to determine whether to include batch support,
# but implemented it in a way that requires modifying the code each time we move
# to a newer OS version.  I will fix this problem in a subsequent change, but for now,
# hardcode to saying we're ANDROID_L so we can isolate this checkin to being
# only changes coming from Invensense.
#
# Setting ANDROID_L to true is perfectly safe even on ANDROID_M because the code
# just requires "ANDROID_L or newer"
