MTK8127发布版本开机时间大约在秒左右如果发现开机时间变长大部分是因为加上了客户订制的东西代码累赘太多了。
、下面看一下开机花时间的是哪些动作 kernel初始化 加载分区 启动Android 加载类 在zygote里面加了 时间发现 这个时间确实很长 包扫描 应用扫描
如何查看启动时间的相关时间点呢看下面 rootmid713l_lp_lvds:/ # cat /proc/bootprof ----------------------------------------0 BOOT PROF (unit:msec)----------------------------------------4098 : preloader722 : lk1829 : lk-Kernel----------------------------------------8743.419000 : Kernel_init_done8758.075154 : SElinux start.14921.341308 : SElinux end.15750.858462 : INIT: on init start16147.198077 : INIT:NAND:Mount_START32627.899693 : INIT:NAND:Mount_END32630.724232 : INIT:PROTECT:fat start32733.226540 : INIT:PROTECT:fat end32736.114693 : INIT:PROTECT_RAW_DISK:Mount_START33582.732924 : INIT:PROTECT_RAW_DISK:Mount_END34489.614386 : INIT: eng build setting38913.817386 : BOOT_Animation:START57958.511387 : Zygote:Preload Start61800.738080 : Zygote:Preload 2774 classes in 3827ms62764.249541 : Zygote:Preload 274 obtain resources in 941ms62800.117541 : Zygote:Preload 31 resources in 35ms62890.361695 : Zygote:Preload End63355.167926 : Android:SysServerInit_START64077.987388 : Android:PackageManagerService_Start64640.584772 : Android:PMS_scan_START70069.473157 : Android:PMS_scan_done:/custom/framework70141.781234 : Android:PMS_scan_done:/system/framework71685.662234 : Android:PMS_scan_done:/system/priv-app75316.111234 : Android:PMS_scan_done:/system/app75327.165004 : Android:PMS_scan_done:/system/vendor/app75328.890158 : Android:PMS_scan_done:/system/vendor/operator/app75330.559850 : Android:PMS_scan_done:/custom/app75337.836927 : Android:PMS_scan_data_start75418.824465 : Android:PMS_scan_data_done:/data/app75420.457542 : Android:PMS_scan_data_done:/data/app-private75422.520927 : Android:PMS_scan_END75840.712234 : Android:PMS_READY80126.832927 : AP_Init:[service]:[com.android.systemui]:[com.android.keyguard/.KeyguardService]:pid:80982539.565158 : AP_Init:[service]:[com.mediatek.security]:[com.mediatek.security/.service.PermControlService]:pid:85183699.413696 : AP_Init:[content provider]:[android.process.acore]:[com.android.providers.contacts/.ContactsProvider2]:pid:92085690.594004 : AP_Init:[service]:[com.google.android.inputmethod.latin]:[com.google.android.inputmethod.latin/com.android.inputmethod.latin.La87394.339466 : AP_Init:[broadcast]:[com.google.android.gms]:[com.google.android.gms/com.google.android.location.internal.NlpNetworkProviderSet91038.825466 : AP_Init:[added application]:[com.android.phone]:[com.android.phone]:pid:990:(PersistAP)91111.352389 : AP_Init:[added application]:[com.mediatek.voicecommand]:[com.mediatek.voicecommand]:pid:1003:(PersistAP)91179.826158 : AP_Init:[added application]:[com.mediatek.bluetooth]:[com.mediatek.bluetooth]:pid:1018:(PersistAP)91248.128928 : AP_Init:[added application]:[com.mediatek.dongle]:[com.mediatek.dongle]:pid:1036:(PersistAP)91372.823851 : AP_Init:[activity]:[com.android.launcher3]:[com.android.launcher3/.Launcher]:pid:105291390.517158 : Android:SysServerInit_END91448.375543 : AP_Init:[service]:[com.android.printspooler]:[com.android.printspooler/.PrintSpoolerService]:pid:106797597.181851 : AP_Init:[content provider]:[android.process.media]:[com.android.providers.downloads/.DownloadProvider]:pid:110097846.665697 : AP_Init:[content provider]:[com.google.process.gapps]:[com.google.android.gsf/.gservices.GservicesProvider]:pid:1119103043.537698 : AP_Init:[broadcast]:[com.google.process.location]:[com.google.android.gms/com.google.android.location.network.LocationProviderC108608.975006 : BOOT_Animation:END、再来看一下 各个阶段的时间 可以通过平板上显示的图标看出来 16147.198077 : INIT:NAND:Mount_START 32627.899693 : INIT:NAND:Mount_END
从这个日志看 NAND 挂载花了秒多 这个时间肯定要优化一下要不然开机时间消耗太大
、从日志分析时间
