本文介绍了一种在Android设备上预安装应用程序的方法。通过修改init.rc文件并使用preinstall.sh脚本来复制APK文件到指定目录，确保首次启动时进行安装。此外，还涉及了Launcher2布局文件的定制。

1. 按如下所示修改：device/softwinner/wing-common/init.rc：

mkdir /data/app 0771 system system

后添加：

# added by shenjianjun for: run /system/bin/preinstall.sh to preinstall all apps in /system/preinstall. 2013.09.13 ..start

exec /system/bin/sh /system/bin/preinstall.sh

# added by shenjianjun for: run /system/bin/preinstall.sh to preinstall all apps in /system/preinstall. 2013.09.13 ..end

然后，注释掉以下内容：

# comed by shenjianjun start

# service preinstall /system/bin/busybox sh /system/bin/preinstall.sh

# user root

# group root

# disabled

# oneshot

# on property:sys.boot_completed=1

# start preinstall

# comed by shenjianjun end

2. preinstall.sh的内容:

#!/system/bin/busybox sh

BUSYBOX="/system/bin/busybox"

mkdir /bootloader

mount -t vfat /dev/block/bootloader /bootloader

if [ ! -e /data/system.notfirstrun ] ; then

echo "do preinstall job"

# added by shenjianjun for: copy all preinstall apks to /data/app, so these apks will be installed by PackageManagerService. 2013.09.13 ..start

$BUSYBOX cp /system/preinstall/*.apk /data/app/

$BUSYBOX cp /sdcard/preinstall/*.apk /data/app/

chown system:system /data/app/*.apk

chmod 0644 /data/app/*.apk

# added by shenjianjun for: copy all preinstall apks to /data/app, so these apks will be installed by PackageManagerService. 2013.09.13 ..end

$BUSYBOX cp /system/etc/chrome-command-line /data/local/

$BUSYBOX chmod 777 /data/local/chrome-command-line

mkdir /databk

mount -t ext4 /dev/block/databk /databk

rm /databk/data_backup.tar

umount /databk

rmdir /databk

$BUSYBOX touch /data/system.notfirstrun

echo "preinstall ok"

elif [ -e /bootloader/data.need.backup ] ; then

echo "data backup:tar /databk/data_backup.tar /data"

mkdir /databk

mount -t ext4 /dev/block/databk /databk

rm /databk/data_backup.tar

$BUSYBOX tar -cf /databk/data_backup.tar /data

rm /bootloader/data.need.backup

umount /databk

rmdir /databk

else

echo "do nothing"

umount /bootloader

rmdir /bootloader

3. 将定制好的布局文件替换Launcher2中的default_workspace.xml然后重新编译Launcher2.

4. 重新编译与打包：

rm $OUT/system

rm $OUT/root

make -j16 && pack
