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
I have small code for ping in a loop:
#!/system/bin/sh
_count=0
_target="dns.google.com"
echo "target :: $_target"
while true;
do
_time="$(date +%H%M%S)"
_count=$((_count + 1))
echo "::::::::::::::::::LOOP"
echo "time :: $_time"
echo "counter :: $_count"
ping -w 1 -c 1 $_target >/dev/null 2>&1 &&
echo "$? ... is reachable" ||
echo "$? ... is down"
done
I'm calling this from android terminal (using SManager).
It should check host availability with a ping in a loop.
The problem is that I get a real response only for the first ping and all the others are bad (output):
$ /system/bin/sh /storage/emulated/0/pinger.sh
target :: dns.google.com
::::::::::::::::::LOOP
time :: 174912
counter :: 1
0 ... is reachable
::::::::::::::::::LOOP
time :: 174912
counter :: 2
1 ... is down
::::::::::::::::::LOOP
time :: 174913
counter :: 3
1 ... is down
::::::::::::::::::LOOP
time :: 174914
counter :: 4
1 ... is down
.
..
...etc.
What is the reason for this behavior?
Lukas
EDIT 2:
New script:
#!/system/bin/sh
_count=0
_target="dns.google.com"
echo "target :: $_target"
while true;
do
_time="$(date +%H%M%S)"
_count=$((_count + 1))
echo "::::::::::::::::::LOOP"
echo "time :: $_time"
echo "counter :: $_count"
ping -w 1 -c 1 $_target
done
Output:
$ /system/bin/sh /storage/emulated/0/pinger.sh

This question already has answers here:
How to make the 'cut' command treat same sequental delimiters as one?
(5 answers)
Closed 4 years ago.
I can get Receive and Transmit bytes for an android device as follows
130|sailfish:/ $ cat /proc/net/dev
Inter-| Receive | Transmit
face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed
rmnet_ipa0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

r_rmnet_data1: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Further, I am trying to filter the received and transmit bytes for an Android device using
cat /proc/net/dev |grep wlan | awk {'print $1'}
but I get the following error
/system/bin/sh: awk: not found
Any alternative way to select the appropriate columns?
I tried Perl as well as
cat /proc/net/dev | grep wlan | perl -lane 'print $F[1]'
which gave
/system/bin/sh: perl: not found
using cut as
cat /proc/net/dev | grep wlan | cut -d' ' -f3
gives
6720980481
but the issues is that I want to cut the tab instead of space as I want to select other tabs as well
I tried
cat /proc/net/dev | grep wlan | cut -d'\t' -f3
and
cat /proc/net/dev | grep wlan | cut -d' ' -f3
but it gives
cut: the delimiter must be a single character
I guess one of the solutions would be to try and install awk and/or perl, but I guess that can't be done for some reason. Anyway, tab is the default separator character in cut. So this should work
cat /proc/net/dev | grep wlan | cut -f3
When after I give the command:
buildozer android debug deploy run
I am getting the following error. Its showing syntax error ?
# Install distribute

It looks like this curl failed for some reason. Could you make sure your buildozer is fully up to date with git, delete your .buildozer directory, and try again?
I would try to update your Python version, make sure it is the latest.
Don't use virtual env. I had a similar issue. Just install builddozer and kivy in the default environment
I have a multi-threaded application(C++,C and pthread library) and I will like to know how much resources(CPU and memory) each thread uses. Is there a way to find out these details on Android?
I have tried
$ adb shell ps -p -t
But, this gives information in the below format,
USER PID PPID VSIZE RSS PRIO NICE RTPRI SCHED WCHAN PC NAME
root 1 0 476 312 20 0 0 0 c037c0e0 000087bc S /init
root 2 0 0 0 20 0 0 0 c031f114 00000000 S kthreadd

root 6 2 0 0 20 0 0 0 c031b4b4 00000000 S khelper
Any way to know which threads are running along with their parent's id will be really helpful.
using
$ adb logcat -v threadtime
prints info about the running process (PID) and the thread (TID).
But, its not enough for my purpose. I want to know how much resources is a particular thread consuming. Any pointers.
ps command in android seems to be very limited compared to linux.
You could try:
ps -t -c APP_NAME
This will show you threads(-t) and the CPU assigned to the thread (-c)
Example:
ps -t -c -p com.whatsapp
-p is thread priority(linux nice value)
