- 对于使用自己开发的网管程序的项目，需要关闭系统网管开关
将build文件中的ro.tr069.enable的值从true改为false，开机时间大幅度缩减，之前一直在29-30S左右，更改后的值在23-24S左右
3.Mstar平台

4.开机时间分析注意事项
- 账号问题：非正式账号可能导致时间变长，这种情况建议使用友商的正常账号先验证一下
- 开机日志分析：
一般分析四个过程
（1）硬件启动消耗时间
上电到开机结束时间减去logcat抓取日志时长
（2）开机到网络连接上
搜开机日志dhcpcd ，表示8.469时刻连网成功

（3）系统校时
代表10.916时刻FTP校时成功

（4）launcher启动
找到对应包名，然后搜start u0
10-25 10:28:35.140 I/ActivityManager( 1968): START u0 {act=cn.cmvideo.action.ITV cmp=tv.icntv.ott/.icntv (has extras)} from pid 2629
（5）launcher启动完成
10-25 10:33:24.417 D/c ( 2738): _finish() start 10-25 10:33:24.417 D/c ( 2738): _finish() end 10-25 10:33:24.418 D/c ( 2738): _done() end
