#!/bin/bash
echo persist.sys.custom.test123二、在Makefile文件中添加需要编译的脚本 代码路径android/build/make/core/Makefile 1、写一个脚本并且定义一个变量把该脚本的路径赋值给该变量
BUILDINFO_SH : build/make/tools/buildinfo.sh
WQINFO_SH : build/make/tools/wqinfo.sh
VENDOR_BUILDINFO_SH : build/make/tools/vendor_buildinfo.sh2、定义一个wq.prop
intermediate_system_build_prop : $(call intermediates-dir-for,ETC,system_build_prop)/build.prop
intermediate_wq_build_prop : $(call intermediates-dir-for,ETC,system_build_prop)/wq.prop3、定义一个编译出来的wq.prop的目录是system/wq.prop
# build.prop
INSTALLED_BUILD_PROP_TARGET : $(TARGET_OUT)/build.prop
ALL_DEFAULT_INSTALLED_MODULES $(INSTALLED_BUILD_PROP_TARGET)
INSTALLED_WQ_PROP_TARGET : $(TARGET_OUT)/wq.prop
ALL_DEFAULT_INSTALLED_MODULES $(INSTALLED_WQ_PROP_TARGET)4、把wqinfo.sh脚本中的内容遍历拷贝到wq.prop文件中 $(hide) cat $(INSTALLED_ANDROID_INFO_TXT_TARGET) | grep require version- | sed -e s/require version-/ro.build.expect./g $$(hide) build/make/tools/post_process_props.py $ $(PRODUCTS.$(INTERNAL_PRODUCT).PRODUCT_SYSTEM_PROPERTY_BLACKLIST)wq_prop_file : $(TARGET_WQ_PROP)
$(intermediate_wq_build_prop): $(WQINFO_SH) $(wq_prop_file)echo Target wqinfo: $mkdir -p $(dir $)$(hide) echo $bash $(WQINFO_SH) $
build_desc :$(INSTALLED_BUILD_PROP_TARGET): $(intermediate_system_build_prop) $(INSTALLED_RECOVERYIMAGE_TARGET)echo Target build info: $$(hide) grep -v ro.product.first_api_level $(intermediate_system_build_prop) $
ifdef INSTALLED_RECOVERYIMAGE_TARGET$(hide) echo ro.expect.recovery_idcat $(RECOVERYIMAGE_ID_FILE) $
endif$(INSTALLED_WQ_PROP_TARGET): $(intermediate_wq_build_prop) $(INSTALLED_RECOVERYIMAGE_TARGET)echo Target build info: $$(hide) grep -v ro.product.first_api_level $(intermediate_wq_build_prop) $5、添加该变量INSTALLED_WQ_PROP_TARGET
include $(BUILD_SYSTEM)/sdk_font.mkdeps : \$(target_notice_file_txt) \$(tools_notice_file_txt) \$(OUT_DOCS)/offline-sdk-timestamp \$(SYMBOLS_ZIP) \$(COVERAGE_ZIP) \$(INSTALLED_SYSTEMIMAGE) \$(INSTALLED_QEMU_SYSTEMIMAGE) \$(INSTALLED_QEMU_VENDORIMAGE) \$(INSTALLED_USERDATAIMAGE_TARGET) \$(INSTALLED_RAMDISK_TARGET) \$(INSTALLED_SDK_BUILD_PROP_TARGET) \$(INSTALLED_BUILD_PROP_TARGET) \$(INSTALLED_WQ_PROP_TARGET) \$(ATREE_FILES) \$(sdk_atree_files) \$(HOST_OUT_EXECUTABLES)/atree \$(HOST_OUT_EXECUTABLES)/line_endings \$(SDK_FONT_DEPS)三、在property_service.cpp文件中加载该文件wq.prop 代码路径android/system/core/init/property_service.cpp
void load_system_props() {load_properties_from_file(/system/build.prop, NULL);load_properties_from_file(/odm/build.prop, NULL);load_properties_from_file(/vendor/build.prop, NULL);load_properties_from_file(/system/wq.prop, NULL);load_properties_from_file(/factory/factory.prop, ro.*);load_recovery_id_prop();
}
最后编译出来会在system下面产生一个wq.prop文件
