Rebuild android code with error “SSL error when connecting to the Jack server. Try 'jack-diagnose”

System: ubuntu 18.04
environment：VirtualBox
The first time I compiled the AOSP source code on Ubuntu 18.04, it passed, and the second time I compiled it failed.
Here is an error message.

I get the same error when I switch to Ubuntu 16.04.Below is a list of the installed Curl versions of Ubuntu 18.04.

I have tried many ways, but I can't solve it. Please help me,thanks.

After the two steps below were applied, the AOSP was successfully built.
Remove TLSv1, TLSv1.1 from jdk.tls.disabledAlgorithms in /etc/java-8-openjdk/security/java.security file
Restart the jack server:
cd /prebuilts/sdk/tools/
./jack-admin kill-server
./jack-admin start-server

I just found the answer, see the link below
enter link description here
Change the code to this,
from /etc/java-8-openjdk/security/java.security remove TLSv1, TLSv1.1.
jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA,
DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL,
include jdk.disabled.namedCurves

I just want to give all the different ways to solve the problem.
There are few ways to overcome this problem, one may work for someone -
Try to simply restart the jack server by below command at your android root folder
./prebuilts/sdk/tools/jack-admin kill-server
./prebuilts/sdk/tools/jack-admin start-server
Try to reduce the number of concurrent services in file $HOME/.jack-server/config.properties
Code:
jack.server.max-service=4
Try to make this value 2 or 1.
If jack server is not running or it hangs when try to run. Than try removing TLSv1, TLSv1.1 from rom /etc/java-8-openjdk/security/java.security
Solution 3 Worked for me.

A way to fix that in your Dockerfile :
USER root
# Fix jack server SSL issue during build
RUN perl -0777 -i -p -e 's/(jdk.tls.disabledAlgorithms=.*?), TLSv1, TLSv1\.1/$1/g' \
/etc/java-8-openjdk/security/java.security

How to parse "adb shell top" to display only CPU or memory usage?

I have the output result from "adb shell top" in a .txt file. I want to get only the CPU usage for my testing app and display it as a table:
Time cpu %
1 18
2 20
3 15
4 19
I have tried cat top.txt | grep Cpu | nl > cpu.txt (followed the instructions from here link), but the file is empty.
Do you have any idea how can I start? I have never used regex and not sure will it help. Please, looking forward hearing any tips :)
User 23%, System 5%, IOW 0%, IRQ 0%
User 434 + Nice 0 + Sys 106 + Idle 1273 + IOW 10 + IRQ 0 + SIRQ 3 = 1826
PID PR CPU% S #THR VSS RSS PCY UID Name
1868 1 20% S 50 1394620K 175176K fg u0_a174 com.test.app
1841 6 2% S 11 1897824K 48632K fg shell uiautomator
4794 1 1% S 148 2334708K 130924K fg system system_server
447 1 1% S 14 422152K 17476K fg system /system/bin/surfaceflinger
29195 1 1% S 21 369676K 20040K fg media

Given your top.txt sample, I would do the following, step by step:
First, select only the lines for your app com.test.app with grep:
grep com.test.app top.txt
Take the third field (delimited by spaces, so this is the CPU usage) by piping into awk:
grep com.test.app top.txt | awk '{ print $3; }'
Add line numbering by piping into nl (the -nln is for left justification):
grep com.test.app top.txt | awk '{ print $3; }' | nl -nln
Finally, just prepend your header with echo (-e and double quotes are needed for newline \n):
echo -e "Time cpu %\n" && grep com.test.app top.txt | awk '{ print $3; }' | nl -nln
This will give you for the sample top.txt:
Time cpu %
1 20%

Jack server failed to (re)start

Can someone please help?
EDIT
Jack server logs are clean, there are no exceptions or errors.
The default ports 8076 and 8077 get blocked as seen in netstat -nlp, which indicates the server is indeed started.
tcp6 0 0 127.0.0.1:8076 :::* LISTEN 19180/java
tcp6 0 0 127.0.0.1:8077 :::* LISTEN 19180/java
The machine I am building the code upon, is behind a proxy.

When I was getting Curl error 7 it was accompanied by an SSL error when running jack-diagnose. The following solution worked for me:
Edit java.security file under /etc/java-8-openjdk/security/
Remove TLSv1, TLSv1.1 from jdk.tls.disabledAlgorithms
Restart the jack server:
cd <your-aosp-home-dir>/prebuilts/sdk/tools/
./jack-admin kill-server
./jack-admin start-server

Try changing service and admin ports both in .jack-settings and .jack-server/config.properties and make sure they match.
Jack server may not be able to use the default ports, especially if you are on a server machine where there are more than one user trying to use Jack.

Command giving no output when being read?

I have a rather weird issue. I can't figure out why it's happening or how to fix it.
The script:
#!system/bin/sh
#set -x
reader() {
t2=-1
grep -v -E "add device|name:" | while IFS=' ' read -r t1 a b c d _; do
t1=${t1%%-*}
t=`expr $t1 - $t2`
if let 't > 0 && t2 > -1'; then
echo "sleep $t"
fi
printf 'sendevent %s' "${a%?}"
printf '%5d %5d %5d\n' "0x$b" "0x$c" "0x$d"
t2=$t1
done
}
let() {
IFS=, command eval [ '$(($*))' -ne 0 ]
}
countDown() {
echo 'Starting in...'
i=4
while [[ $i -gt 1 ]]; do
i=$(($i-1))
echo "$i"
sleep 1
done
printf '%s\n\n\n' 'Go!'
# echo "$*"
"$#" | reader
}
clear
printf '%s >' 'Catch by [n]umber of events or [t]imeout?'
read type
case $type in
n)
printf '%s >' 'Events to catch?'
read arg
echo "Gonna catch $arg events!"
countDown getevent -t -c "$arg"
;;
t)
printf '%s >' 'Timeout (in seconds)?'
read arg
echo "Gonna catch events for $arg seconds!"
countDown timeout -t $arg getevent -t
esac
The goal of the script:
Catch the user's interactions (e.g. key presses, screen taps, etc) using the getevent command and outputs a script to stdout, that can be used to replicate these events.
Additional info:
getevent's output is in hexadecimal format
sendevent accepts decimal format
Expected output:
Catch by [n]umber or by [t]imeout? n
Events to catch? > 4
Gonna catch 4 events...
Starting in...

Go!
sendevent /dev/input/event5 1 102 1
sendevent /dev/input/event5 0 0 0
sleep 3
sendevent /dev/input/event5 1 102 0
sendevent /dev/input/event5 0 0 0
The problem:
The code runs as expected when "n" is picked. When "t" is picked, the script exits after the specified amount of seconds. However, it does not output anything - the first line of the while loop doesn't even run.
With set -x, here's what's shown (last few lines):
+ printf %s\n\n\n Go!
Go!
+ reader
+ t2=-1
+ grep -v -E add device|name:
+ timeout -t 5 getevent -t
+ IFS = read -r t1 a b c d _
Running this alone shows output to stdout (output that's supposed to be read and modified inside the while loop):
timeout -t 5 getevent -t
Any ideas?
Thanks.
EDIT:
Alright, so I think it's a buffering issue. Basically this gives a similar issue:
getevent > output
The file gets updated every bunch of events, but not instantly (and might never update if not enough events are made). I'm not aware of any work around on Android.

I think there's no way of enabling line-buffering in busybox's grep, but you can do something like this:
$ adb shell timeout -t 10 getevent -t | \
grep --line-buffered -v -E "add device|name:" | \
while read line; do echo "READ: $line"; done

Here was basically that stuff I translated from your code before being mangled by bug workarounds. Replacing the one command I don't have with cat on the timeout branch, it runs correctly with your sample input in Busybox sh, dash, mksh, bash, and ksh93.
Since so many basic things about the shell and applications are broken, it isn't surprising this doesn't work. I would make sure Busybox is up-to-date and see whether the arithmetic and other bugs you keep hitting are reproducible on other systems, and report bugs if this code doesn't work.

Had the same problem, and remembered a trick that I first used in MS-DOS 3.30, and later in Cygwin(not for timeout, but the more command is a magical bullet for lots of redirect problems):
timeout -t 8 getevent | more > getevent.txt
works well in Total Commander's shell
with su (not sh)
You're welcome :-)

how do i get rid of the bugs (what is wrong with my script )

i have written a bash script that uses nice, renice and oom priority(optional ), to bulletproof apps periodically, it check for the app if running renices it else, nices it for the next time running, but there are bugs and because I am new to bash scripting I needed some help, this is for a sony ericsson xperia x10 running gingerbread, but other than the app names, all the commands are standard busybox commands
#!/system/bin/sh

then

if you can find the error or show me a good scripting guide i will be thankful

In a shell there is no such statement as if[. You need a space after each if.
Also, after:
phoneid='pidof com.android.phone'
you have in your variable text: "pidof com.android.phone" instead of output of that command. You need to use `command param ...` or (preferably) $(command param ...) syntax.
Remember to check you shell syntax with:
/bin/sh -n myscript.sh
The command above (run on your PC) will not try to run the script, just check the syntax.
Also, You have a lot of uneeded semicolons, but this will not fail your script.
