RK3288[android 7.1]調試筆記 開機進不了系統報以下log:init: Service 'bootanim' is being killed...

開機進不了系統報以下log:init: Service ‘bootanim’ is being killed…

開機進不了系統查看log，得知原因是由於開機動畫這條服務進程會被殺掉導致一直進不去系統

**原因：
因爲bootanimation服務的進程uid與AID_SYSTEM（system）不一致，也就是匹配bootanimation服務的進程uid不一致,我的uid是graphics

解決方法：
直接修改進程uid。找到啓動bootanimation服務的地方**

service bootanim /system/bin/bootanimation
    class core
    user graphics                          //將user graphics改爲user system 
    group graphics audio
    disabled
    oneshot
    

修改路徑爲/device/rockchip/rk3288/rk3288_box/init.rc文件，以下就是我修改的補丁
