一、如何编译出vendor.img

1. 首先找到产品对应BoardConfig.mk

路径：LINUX/android/

device/项目/产品/BoardConfig.mk

2. 修改BoardConfig.mk

设置下面代码中的ENABLE_VENDOR_IMAGE为true。

#Enable split vendor image

ENABLE_VENDOR_IMAGE := true

#ENABLE_VENDOR_IMAGE := false

ifeq ($(ENABLE_VENDOR_IMAGE), true)

BOARD_VENDORIMAGE_PARTITION_SIZE := 838860800

BOARD_VENDORIMAGE_FILE_SYSTEM_TYPE := ext4

TARGET_COPY_OUT_VENDOR := vendor

BOARD_PROPERTY_OVERRIDES_SPLIT_ENABLED := true

endif

3. 编译

make vendorimage -j4

二、如何编译packages/apps/Settings并进行push

1)进入packages/apps/Settings　　 执行mm；

2)执行

adb root;

adb disable-verity;

adb remount;

adb push out/target/product/***/system/priv-app/Settings/Settings.apk system/priv-app/Settings/

三、如何编译frameworks/base/packages/SettingsLib

1. 修改frameworks/base/packages/SettingsLib/Android.mk

屏蔽Android.mk里面的最后一行，如下

# For the test package.

#include $(call all-makefiles-under, $(LOCAL_PATH))

2. 编译

source ./build/envsetup.sh

lunch ***

进入frameworks/base/packages/SettingsLib目录下

执行mm

3. 【注意】

frameworks/base/packages/SettingsLib下的修改如何编译后进行push到手机？

解决方案：

1)进入packages/apps/Settings　　 执行mm；

2)执行

adb root;

adb disable-verity;

adb remount;

adb push out/target/product/***/system/priv-app/Settings/Settings.apk system/priv-app/Settings/

3)如果

有lib文件生成，则也要进行adb push操作。

四、编译boot.img

make bootimage

五、编译package/app/Nfc

make NfcNci
