# Script to start a set of apps in order and then in each iteration
# switch the focus to each one. For each iteration, the time to start
# the app is reported as measured using atrace events and via am ThisTime.
# The output also reports if applications are restarted (eg, killed by
# LMK since previous iteration) or if there were any direct reclaim
# events.
#
# Variation: the "-T" option skips all of the atrace instramentation and
# attempts to start the apps as quickly as possible.
#
# Example 1: start all default apps. 2 iterations
#
# ./systemapps.sh -i 2
#
# Example 2: just start chrome, feedly, and the home screen in a loop
#
# ./systemapps.sh -L "chrome feedly home" -i 5
#
# Example 3: just start the default apps as quickly as possible
#
# ./systemapps.sh -T
#
# Other options are described below.
