aystshen/Android-preload

The file is built into the system partition, and the file is automatically copied to the sdcard directory for the first boot.

Android-preload

This repository solves the problem of Android built-in files. The default file exists in the system/preload directory. This script starts and copies the files in the system/preload directory to the sdcard directory.

Usage

1. Copy the preload directory to vendor/rockchip/common/.

shenhb@dqrd01:~/vendor/rockchip/common/preload$ tree
.
├── Android.mk
├── preload
├── preload.mk
└── preload.sh

2. Modify device/rockchip/common/init.rockchip.rc and add the following code:

#preload
service preload /system/xbin/preload.sh
    class late_start
    user root
    group media_rw
    oneshot

3. Modify vendor/rockchip/common/BoardConfigVendor.mk and add the following code:

PRODUCT_HAVE_PRELOAD ?= true

4. Modify vendor/rockchip/common/device-vendor.mk and add the following code:

ifeq ($(PRODUCT_HAVE_PRELOAD),true)
$(call inherit-product-if-exists, vendor/rockchip/common/preload/preload.mk)
endif

For SEAndroid

1. Modify device/rockchip/common/init.rockchip.rc and add the following code:

#preload
service preload /system/xbin/preload.sh
    class late_start
    user root
    group media_rw
    oneshot

2. Modify device/rockchip/common/sepolicy/file_contexts and add the following code:

# for preload
/system/xbin/preload.sh            u:object_r:preload_exec:s0

3. Modify device/rockchip/common/sepolicy/init.te and add the following code:

domain_trans(init, preload_exec, preload)

4. Add device/rockchip/common/sepolicy/preload.te file.

type preload, domain, coredomain, mlstrustedsubject;
type preload_exec, exec_type, vendor_file_type, file_type;
init_daemon_domain(preload)
