systemapps.sh revision ae1f93cc3cef9c8c790330dd09f2ff87bf38eabc 
1# Script to start a set of apps in order and then in each iteration
2# switch the focus to each one. For each iteration, the time to start
3# the app is reported as measured using atrace events and via am ThisTime.
4# The output also reports if applications are restarted (eg, killed by
5# LMK since previous iteration) or if there were any direct reclaim
6# events.
7#
8# Variation: the "-T" option skips all of the atrace instramentation and
9# attempts to start the apps as quickly as possible.
10#
11# Example 1: start all default apps. 2 iterations
12#
13# ./systemapps.sh -i 2
14#
15# Example 2: just start chrome, feedly, and the home screen in a loop
16#
17# ./systemapps.sh -L "chrome feedly home" -i 5
18#
19# Example 3: just start the default apps as quickly as possible
20#
21# ./systemapps.sh -T
22#
23# Other options are described below.
