最近在编译一个老项目，项目中依赖了很多第三方库，用gradle编译要20-30分钟，而且内存开销很大。
公司配的15G内存的电脑，一次编译能用到14G。
编译的时候，ubuntu有概率会卡死（卡死的问题，网上的方法我尝试了一轮，但是没有用，物理重启电脑有效）。
此为背景。昨晚重启之后，我发现adb用不了了。报错如下：

adb devices
adb shell
error: protocol fault (couldn't read status): Connection reset by peer

adb start-server
adb: failed to check server version: protocol fault (couldn't read status): Connection reset by peer

最后的解决办法

step 0

mv ~/.android ~/Download

step 1 diable mDNS for wireless debugging

In Android Studio: Open File / Settings
Go to: Settings / Build, Execution, Deployment / Debugger
In Section "Android Debug Bridge (abd)":
Uncheck "Enable adb mDNS for wireless debugging"

step 2

Restart Android Studio.

step 3

restart the computer.

step 4

adb kill-server
adb server -a

排查过程

排查是否端口占用

adb nodaemon start-server
netstat -tuln | grep 5353

把占用5353端口的udp都给去掉.

export ADB_TRACE=all

wget http://dl-ssl.google.com/android/repository/platform-tools_r30.0.4-linux.zip
./adb start-server

netstat -tuln | grep 5037

把占用5037端口的tcp都给去掉.

重启电脑试图恢复

回家冷静一下

按 start-server 的日志看有没有人遇到类似的问题
