[Hi3751V811][Android8.0]Android系统开机如何启动自己的可执行文件

一、实现编译时执行对此文件的拷贝。

执行文件存放路径： android/device/hisilicon/bigfish/etc/
目标地址为：/system/etc/

目录：/home/nova/hisi/android/device/hisilicon/Hi3751V811/device_copyfile.mk

#hisi start boot
PRODUCT_COPY_FILES += \ device/hisilicon/bigfish/etc/fstab.bigfish.androido:vendor/etc/fstab.$(TARGET_BOARD_PLATFORM) \ device/hisilicon/bigfish/etc/init.hidolphin.rc:root/init.hidolphin.rc \ device/hisilicon/bigfish/etc/init.bigfish.rc:root/init.$(TARGET_BOARD_PLATFORM).rc \ device/hisilicon/bigfish/etc/ueventd.bigfish.rc:root/ueventd.$(TARGET_BOARD_PLATFORM).rc

我们可以加一条

PRODUCT_COPY_FILES += \ device/hisilicon/bigfish/etc/*.sh:/system/etc/

这样，Android在执行编译的时候就会把新增文件拷贝至相应的目标路径去了，拷贝动作已经实现。

二、添加启动动作，使Android在启动时候执行。

目录：android/device/hisilicon/bigfish/etc/init.bigfish.rc
以memcserver为例：

# Add memcserver
service memcserver /vendor/bin/memcserver class main user root group root oneshot

三、挂载权限

目录：android/system/core/libcutils/fs_config.c

static const struct fs_path_config android_files[] = { /* clang-format off */ { 00644, AID_SYSTEM, AID_SYSTEM, 0, "data/app/*" }, { 00644, AID_SYSTEM, AID_SYSTEM, 0, "data/app-ephemeral/*" }, { 00644, AID_SYSTEM, AID_SYSTEM, 0, "data/app-private/*" }, { 00644, AID_APP, AID_APP, 0, "data/data/*" }, { 00644, AID_MEDIA_RW,  AID_MEDIA_RW,  0, "data/media/*" }, { 00640, AID_ROOT, AID_SHELL, 0, "data/nativetest/tests.txt" }, { 00640, AID_ROOT, AID_SHELL, 0, "data/nativetest64/tests.txt" }, ... { 00550, AID_ROOT, AID_SHELL, 0, "system/etc/init.goldfish.sh" }, { 00550, AID_ROOT, AID_SHELL, 0, "system/etc/init.ril" }, { 00555, AID_ROOT, AID_ROOT, 0, "system/etc/ppp/*" }, { 00555, AID_ROOT, AID_ROOT, 0, "system/etc/rc.*" },
}
