解决修改以太网配置后立即断电配置丢失问题
因为以太网配置结果是保存在本地文件中，当设置完成后立即断电，文件还在缓存中，并未真正写到磁盘，所以会导致配置丢失。这里在修改配置完成后增加磁盘同步，强制文件写入磁盘，从而解决断电配置丢失问题。

二、Android支持多摄像头
某些平台默认只支持2个摄像头，但随着 AI 越来越热门，图像识别应用越来越广泛，我们经常需要用到更多的摄像头。下面修改使 Android 能够支持最多10个摄像头。

三、Android替换默认签名
生成自定义签名
创建签名生成脚本
创建 build/make/target/product/security/mkkey.sh 文件，内容如下：
#/bin/sh!
if [ $# -ne 1 ] ; then
echo "Create a test certificate key."
echo "Usage: $0 NAME"
echo "Will generate NAME.pk8 and NAME.x509.pem"
echo "/C=CN/ST=Guangdong/L=ShenZhen/O=Company/OU=Team/CN=Company/emailAddress=xxx@gmail.com"
exit 1
fi
openssl genrsa -3 -out $1.pem 2048
openssl req -new -x509 -key $1.pem -out $1.x509.pem -days 10000 \
-subj '/C=CN/ST=Guangdong/L=ShenZhen/O=Company/OU=Team/CN=Company/emailAddress=xxx@gmail.com'
openssl pkcs8 -in $1.pem -topk8 -outform DER -out $1.pk8 -nocrypt
其中 『-subj』参数请替换为自定义值。
生成签名
通过 mkkey.sh，分别生成 media、platform、shared、testkey、verity 相关 key。
./mkkey.sh media
./mkkey.sh platform
./mkkey.sh shared
./mkkey.sh testkey
./mkkey.sh verity
生成文件如下：
.
├── Android.mk
├── media.pem
├── media.pk8
├── media.x509.pem
├── mkkey.sh
├── platform.pem
├── platform.pk8
├── platform.x509.pem
├── README
├── shared.pem
├── shared.pk8
├── shared.x509.pem
├── testkey.pem
├── testkey.pk8
├── testkey.x509.pem
├── verity_key
├── verity.pk8
└── verity.x509.pem
对全部内置应用重新签名
现在已经生成了自定义签名，但原内置的很多预编译应用还是使用的原 Android 默认签名，如果不对这些应用进行重新签名，将无法使用。所以，这里需要对全部预编译应用使用新的签名 key 进行重新签名。
创建批量签名脚本
创建批量签名脚本：vendor/rockchip/common/apps/ApkBatchSign/apksign.sh，内容如下：
#!/bin/bash
usage()
{
echo "USAGE: [r] [-s source directory] [-k key directory]"
echo "No ARGS means use default build option"
echo "WHERE: -s = set source directory"
echo " -k = key directory"
echo " -r = replace source file"
echo " -h = help"
exit 1
}
CUR_DIR=$PWD
SOURCE=$CUR_DIR
SIGNAPK_JAR=signapk.jar
KEY=$CUR_DIR
REPLACE=false
while getopts "s:k:r" opt
do
case $opt in
s)
SOURCE=$OPTARG
;;
k)
KEY=$OPTARG
;;
r)
REPLACE=true
;;
h)
usage ;;
?)
usage ;;
esac
done
function sign(){
for filename in $1/*
do
if [ -d $filename ]
then
sign $filename
elif [ "${filename##*.}" = "apk" ]; then
echo "签名: "$filename
tempname=$(dirname $filename)"/"$(basename $filename .apk)"_signed.apk"
java -jar $KEY/signapk.jar $KEY/platform.x509.pem $KEY/platform.pk8 $filename $tempname
if [ $REPLACE = true ]; then
rm -rf $filename
mv -vf $tempname $filename
fi
fi
done
}
sign $SOURCE
使用批量签名脚本对全部应用签名
参数解释：
● -s 指定 APK 路径，默认会递归子目录查找。
● -k 指定签名 key 路径。需要包含下面三个文件：
.
├── platform.pk8
├── platform.x509.pem
└── signapk.jar
例如：
ApkBatchSign$ ./apksign.sh -s . -k topband_sign -r
签名: ./dir/BooksProvider.apk
‘./dir/BooksProvider_signed.apk’ -> ‘./dir/BooksProvider.apk’
签名: ./RkEbookReader.apk
‘./RkEbookReader_signed.apk’ -> ‘./RkEbookReader.apk’
