| # 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. |
