使用adb 命令(atrace)抓起systrace的方法。

adb shell atrace -c -b 10240 --async_start -z gfx 

1. 执行查看adb shell atrace 功能

atrace --h
atrace: invalid option -- h

usage: atrace [options] [categories...]
options include:
  -a appname      enable app-level tracing for a comma separated list of cmdlines; * is a wildcard matching any process
  -b N            use a trace buffer size of N KB
  -c              trace into a circular buffer
  -f filename     use the categories written in a file as space-separated
                    values in a line
  -k fname,...    trace the listed kernel functions
  -n              ignore signals
  -s N            sleep for N seconds before tracing [default 0]
  -t N            trace for N seconds [default 5]
  -z              compress the trace dump
  --async_start   start circular trace and return immediately
  --async_dump    dump the current contents of circular trace buffer
  --async_stop    stop tracing and dump the current contents of circular
                    trace buffer
  --stream        stream trace to stdout as it enters the trace buffer
                    Note: this can take significant CPU time, and is best
                    used for measuring things that are not affected by
                    CPU performance, like pagecache usage.
  --list_categories
                  list the available tracing categories
 -o filename      write the trace to the specified file instead
                    of stdout.
 atrace --list_categories   列出连接设备可用的跟踪类别参数(后面分析会看到这些参数)。

1.普通抓取方法

adb shell "atrace gfx -b 20480 -t 1 | grep xxx/xxx.SGameActivity"

2.指向文件输出使用

adb shell atrace -c -b 10240 --async_start -z gfx input view wm am sched load idle freq
adb shell atrace -c -b 10240 --async_stop -z gfx input view wm am sched load idle freq > d:/trace_raw

或者
adb shell "atrace gfx -b 20480 -t 1 | grep xxx/xxx.SGameActivity" > d:/trace_raw

3.不间断循环抓取

开始:
adb shell atrace -c -b 10240 --async_start gfx

执行循环输出
adb shell atrace -c -b 10240 --async_dump gfx

停止
adb shell atrace -c -b 10240 --async_stop
