本文以Android 5.1的A83T octopus-f1工程为例.
预装APK分为四种priv-app, preinstall, precopy, app
out/target/product/octopus-f1/system/priv-app 系统默认APP
out/target/product/octopus-f1/system/app 用户APP
out/target/product/octopus-f1/system/precopy: 第一次启动Launcher之前安装到/data目录, 可卸载
out/target/product/octopus-f1/system/preinstall: 第一次系统启动安装到/data目录, 可卸载
先装这四个文件夹下的文件全部删除.
配置文件为.mk结尾的文件主要在 build/target/product, device/softwinner/octopus-f1目录下.
将PRODUCT_PACKAGES是不需要的项目删除:
build/target/product/core.mk:
PRODUCT_PACKAGES += \
CertInstaller \
DeskClock \
Launcher2 \
Settings

build\target\product\core_base.mk:等等
具体APK作用, 参看网址 Android系统裁剪 apk
另外在全局查找可使用find+grep组合, 如:
root@virtual-machine:/home/root/CQA83TAndroid_v2.1.0_bv3/android# find . -type f -name \*.mk | xargs grep Dialer -in ./external/srec/config/en.us/config.mk:19: VoiceDialer.g2g \ ./external/srec/config/en.us/Android.mk:50:# ALL_PREBUILT += $(G2G_INSTALL_PATH)/VoiceDialer.g2g \ ./device/softwinner/octopus-f1/ril_modem/huawei/mu509/huawei_mu509.mk:8: Dialer \ ./device/softwinner/octopus-f1/ril_modem/Oviphone/em55/oviphone_em55.mk:11: device/softwinner/fiber-3g/ril_modem/Oviphone/em55/wcdma-ppp-on-dialer:system/etc/ppp/wcdma-ppp-on-dialer ./packages/services/Telephony/Android.mk:3:# Build the Phone app which includes the emergency dialer. See Contacts ./packages/services/Telephony/Android.mk:4:# for the 'other' dialer. ./packages/apps/Dialer/tests/Android.mk:15:LOCAL_PACKAGE_NAME := DialerTests ./packages/apps/Dialer/tests/Android.mk:17:LOCAL_INSTRUMENTATION_FOR := Dialer ./packages/apps/Dialer/Android.mk:43:LOCAL_PACKAGE_NAME := Dialer ./packages/apps/VoiceDialer/tests/Android.mk:12:LOCAL_PACKAGE_NAME := VoiceDialerTests ./packages/apps/VoiceDialer/tests/Android.mk:14:LOCAL_INSTRUMENTATION_FOR := VoiceDialer ./packages/apps/VoiceDialer/Android.mk:8:# LOCAL_PACKAGE_NAME := VoiceDialer ./packages/apps/VoiceDialer/Android.mk:16:# Install the srec data files if VoiceDialer.apk is installed to system image. ./build/target/product/full_base_telephony.mk:23:# VoiceDialer ./build/target/product/sdk_base.mk:32:# Dialer
如此可找到对应的mk将其删除即可.
注意如果要删除apk, 必须先把out中的apk删除才行, 再进行android make.
