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 ] ; thenecho "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
fiopenssl genrsa -3 -out $1.pem 2048openssl 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/bashusage()
{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=falsewhile getopts "s:k:r" opt
docase $opt ins)SOURCE=$OPTARG;;k)KEY=$OPTARG;;r)REPLACE=true;;h)usage ;;?)usage ;;esac
donefunction sign(){for filename in $1/*do  if [ -d $filename ]then sign $filenameelif [ "${filename##*.}" = "apk" ]; thenecho "签名: "$filenametempname=$(dirname $filename)"/"$(basename $filename .apk)"_signed.apk"java -jar $KEY/signapk.jar $KEY/platform.x509.pem $KEY/platform.pk8 $filename $tempnameif [ $REPLACE = true ]; thenrm -rf $filenamemv -vf $tempname $filenamefifi  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’
