由于客户的几个app中使用的.so文件是同名的，所以不能单独把.so提取出来，内置这些.so到系统库中.。只能这样来实现，系统在第一次刷机完后，用install 的方式来安装这些应用.

整体思路如下：

1.把这些要install的应用放置在freescale\imx7\device\fsl\shiyuan_7d_eink\preinstall这个路径。包括安装apk脚本和Android.mk文件,和启动这些apk的脚本文件。

其中安装apk脚本如下:

#!/system/bin/busybox sh

BUSYBOX="/system/bin/busybox"
if [ ! -e /data/system.notfirstrun ]; then
echo "do preinstall job"

   /system/bin/sh /system/bin/pm preinstall /system/preinstall

$BUSYBOX touch /data/system.notfirstrun

echo "preinstall ok"
fi

Android.mk：

LOCAL_PATH := $(call my-dir)

#########################
include $(CLEAR_VARS)
LOCAL_MODULE := SYAirdisk-ink.apk
LOCAL_MODULE_TAGS := optional
LOCAL_CERTIFICATE := PRESIGNED
LOCAL_MODULE_PATH := $(TARGET_OUT)/preinstall
LOCAL_MODULE_CLASS := APPS
LOCAL_SRC_FILES := $(LOCAL_MODULE)
include $(BUILD_PREBUILT)

#########################
include $(CLEAR_VARS)
LOCAL_MODULE := SYCCASworker_ink.apk
LOCAL_MODULE_TAGS := optional
LOCAL_CERTIFICATE := PRESIGNED
LOCAL_MODULE_PATH := $(TARGET_OUT)/preinstall
LOCAL_MODULE_CLASS := APPS
LOCAL_SRC_FILES := $(LOCAL_MODULE)
include $(BUILD_PREBUILT)

#########################
include $(CLEAR_VARS)
LOCAL_MODULE := SYLocalserver_ink.apk
LOCAL_MODULE_TAGS := optional
LOCAL_CERTIFICATE := PRESIGNED
LOCAL_MODULE_PATH := $(TARGET_OUT)/preinstall
LOCAL_MODULE_CLASS := APPS
LOCAL_SRC_FILES := $(LOCAL_MODULE)
include $(BUILD_PREBUILT)

#########################
include $(CLEAR_VARS)
just_copy_to :=system/bin/preinstall.sh
just_copy_from:=$(LOCAL_PATH)/preinstall.sh
$(shell mkdir -p $(just_copy_to))
$(shell cp $(just_copy_from) $(just_copy_to))

启动apk的脚本如下:

#!/system/bin/busybox sh
echo "start two important service process"
am startservice org.golang.app.ccasworker/.GoNativeService
sleep 1
am startservice org.golang.app.localserver/.GoNativeAidlService
sleep 1
am startservice org.golang.app.airdisk/.GoNativeService
echo "end of the starting operation"

2.在apk文件，安装apk脚本，Android.mk文件，和启动apk脚本文件放置在对应路径后；把对应的apk拷贝到/system/preinstall路径下，实现如下:

#For WhiteListApp and preinstall apks;add by Jack 2019/04/09
PRODUCT_COPY_FILES += \
   device/fsl/shiyuan_7d_eink/WhiteListApp.properties:system/etc/WhiteListApp.properties   \
device/fsl/shiyuan_7d_eink/preinstall/SYCCASworker_ink.apk:system/preinstall/SYCCASworker_ink.apk   \
   device/fsl/shiyuan_7d_eink/preinstall/SYLocalserver_ink.apk:system/preinstall/SYLocalserver_ink.apk   \
   device/fsl/shiyuan_7d_eink/preinstall/SYAirdisk-ink.apk:system/preinstall/SYAirdisk-ink.apk

把preinstall.sh，和startTargetProc.sh两个脚本拷贝到Android系统路径/system/bin下

PRODUCT_COPY_FILES +=   \
   device/fsl/shiyuan_7d_eink/preinstall/preinstall.sh:system/bin/preinstall.sh   \
   device/fsl/shiyuan_7d_eink/preinstall/startTargetProc.sh:system/bin/startTargetProc.sh

那么至此，Android源码编译后的结果是，脚本已经拷贝到/system/bin下面，apk.拷贝到/system/preinstall路径下；

3.刷完机后，Android系统启动的时候，会启动init.rc脚本文件，在这个脚本文件中调用安装apk的脚本，和调用启动apk的脚本。

a.init.rc 中调用安装应用脚本

service preinstall /system/bin/busybox sh /system/bin/preinstall.sh
user root
group root
disabled
oneshot

b.init.rc中嵌入调用启动apk的脚本

#start the two services
#触发器，当系统属性dev.bootcomplete=1即启动完成时触发
on property:dev.bootcomplete=1
start startservice
service startservice /system/bin/startTargetProc.sh
   class late_start
   user root
   group root
   disabled
   oneshot

4，至此，第一次刷完机，预安装的应用会安装在/data/app路径下。

再次启动系统，就会执行启动应用脚本，把应用默认启动起来.

总结:

此次预安装的可卸载的apk中的总的思路，是要把目标apk，从源码移动到/system/preinstall路径下，不能移动到/system/app，也不能移动到/system/priv-app下。所以需要copy,而不能通过Android.mk编译进系统。
