Android 11 usb调试默认打开

一. 修改ro.debuggable 默认值

build\make\core\main.mk

ifeq (true,$(strip $(enable_target_debugging)))
  # Target is more debuggable and adbd is on by default
  #ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=1
  # Enable Dalvik lock contention logging.
  ADDITIONAL_BUILD_PROPERTIES += dalvik.vm.lockprof.threshold=500
else # !enable_target_debugging
  # Target is less debuggable and adbd is off by default
 # ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=0

ADDITIONAL_DEFAULT_PROPERTIES += ro.debuggable=1
endif # !enable_target_debugging
## eng ##

二. 修改授权框(默认不弹出, 设置允许)

system\core\adb\daemon\main.cpp

int adbd_main(int server_port) 

//根据宏控制配置是否默认允许

if (android::base::GetBoolProperty("xxx.xxx.usb_def_debuger", true)) {
        auth_required = false;
    } 

三. 解决  打开"开发者选项" 崩溃

avc: denied { read } for 
name="u:object_r:logpersistd_logging_prop:s0" 
dev="tmpfs" 
ino=7775 
scontext=u:r:system_app:s0 
tcontext=u:object_r:logpersistd_logging_prop:s0 
tclass=file 
permissive=0

修改权限

system\sepolicy\prebuilts\api\30.0\private\system_app.te

set_prop(system_app, log_tag_prop)
# add fix bug Settings development fatal
set_prop(system_app, logpersistd_logging_prop)
userdebug_or_eng(`set_prop(system_app, logpersistd_logging_prop)')

system\sepolicy\private\system_app.te

set_prop(system_app, log_tag_prop)
# add fix bug Settings development fatal
set_prop(system_app, logpersistd_logging_prop)
userdebug_or_eng(`set_prop(system_app, logpersistd_logging_prop)')
