1. 配置文件：config.txt

buffers: {
    size_kb: 522240
    fill_policy: RING_BUFFER
}

buffers: {
    size_kb: 2048
    fill_policy: RING_BUFFER
}

    config {
        name: "linux.process_stats"

        }
    }
}

            atrace_apps: "*"
        }
    }
}
duration_ms: 15000

2. 抓trace的命令文件： perfetto.sh

备注说明：生成一个.html结尾的，保存在“/home/xadz1307/trace/”的文件。

#!/bin/bash
date_time=$(date +"%Y_%m%d_%H%M")
echo $date_time
product_name=`adb shell getprop ro.product.name`
FILE_NAME=$product_name"_"$date_time
echo $FILE_NAME
CURRENT_PATH=$(cd $(dirname $0); pwd)
echo $CURRENT_PATH
TRACE_PATH=/home/xadz1307/trace/

adb push config.txt /data/misc/perfetto-traces/config.txt

adb shell "perfetto -c /data/misc/perfetto-traces/config.txt --txt -o /data/misc/perfetto-traces/$FILE_NAME.html"

adb pull /data/misc/perfetto-traces/$FILE_NAME.html $TRACE_PATH

3. 打开trace文件：

google浏览器-打开--  --> open trace file
