ADB pair unknown command using r32 platform tools

I've just downloaded a fresh install of SDK platform tools since I don't need the IDE.
Version: r32.0.0
When using adb pair i get the following:
PS C:\*userpath*\platform-tools_r32.0.0-windows\platform-tools> adb pair
adb: usage: unknown command pair
Tried downloading fresh again, and still the same error. Do I need to install other packages aswell? I just want the command line tools.

Ended up using an ADB version I didn't know was installed. Opening PowerShell directly in the folder and running
./adb
Made it work, just fine.

ADB server version (36) doesn't match this client (39); killing [duplicate]

This question already has answers here:
adb server version doesn't match this client
(41 answers)
Closed 5 years ago.
After installing the Android O preview on a test device my ADB stopped working and started giving me this error.
adb server version (36) doesn't match this client (39); killing...

The only answers I have come across on this issue referred to Genymotion being out of sync with ADB but I don’t use Genymotion. Any help would be greatly appreciated. I have already wiped and reinstalled Android Studio as well as all of its tools and settings yet seem to still have this issue.

This works for me...
go to GenyMotion settings -> ADB tab
instead of Use Genymotion Android tools, choose custom Android SDK Tools and then browse your installed SDK.

In my case this error occured when I set up my environment adb path as ~/.android-sdk/platform-tools (which happens when e.g. android-platform-tools is installed via homebrew), which version was 36, but Android Studio project has Android SDK next path ~/Library/Android/sdk which adb version was 39.
I have changed my PATH to platform-tools to ~/Library/Android/sdk/platform-tools and error was solved

The main point that all the others have missed, is that you will get this error when you have a running adb process in the background. So the first step is to find it and kill it:
ps aux | grep adb
user 46803 0.0 0.0 2442020 816 s023 S+ 5:07AM 0:00.00 grep adb
user 46636 0.0 0.0 651740 3084 ?? S 5:07AM 0:00.02 adb -P 5037 fork-server server
When you find it, you can kill it using kill -9 46636.
In my case, the problem was an old version of adb coming from GapDebug. If you got this with GapDebug, get out of it and then do
adb kill-server
adb start-server
because with GapDebug in the background, when you kill the adb server, GapDebug will start its own copy immediately, causing the start-server to be ignored

I had the same problem with Android Studio - adb server version (37) doesn't match this client (39). I fixed by the following solution :
In Android Studio go to Tools -> Android -> SDK Manager
In the SDK Tools tab untick Android SDK Platform-Tools, click Apply to uninstall.
I then renamed the folder Platform-Tools to Platform-ToolsOld
Then back in the SDK Manager re-tick the Platform-Tools to re-install.

As mentioned by others here, that you could have two adb's running ... And to add to these answers from a Linux box perspective ( for the next newbie who is working from Linux );
Uninstall your distro's android-tools ( use zypper or yum etc )
# zypper -v rm android-tools
Find where your other adb is
# find /home -iname "*adb"|grep -i android
Say it was at ;
/home/developer/Android/Sdk/platform-tools/adb
Then Make a softlink to it in the /usr/bin folder
ln -s /home/developer/Android/Sdk/platform-tools/adb /usr/bin/adb
Then;
# adb start-server

I had the same error. In my case, using Appium, I had two versions of ADB
$ /usr/local/bin/adb version 36
and
$ /Users/user/Library/Android/sdk/platform-tools/adb version 39
The solution was:
be sure that your $PATH in bash_profile is pointing to: /Users/user/Library/Android/sdk/platform-tools/
stop the adb server: adb kill-server and check Appium is stopped.
delete the adb version 36 (or you can rename it to have a backup): rm /usr/local/bin/adb
start adb server: adb start-server or just starting Appium

You have two versions of ADB
$ /usr/local/bin/adb version
Android Debug Bridge version 1.0.36
Revision 0e9850346394-android
and
$ /Users/user/Library/Android/sdk/platform-tools/adb version
Android Debug Bridge version 1.0.39
Revision 3db08f2c6889-android
You could see which one your PATH is pointing to (echo $PATH) but I fixed it with a adb stop-server on one version and a adb start-server on the other.

To add yet another potential solution, Helium by Clockworkmod has it's own version of ADB built in that kept being started. Exiting the Helium Desktop application resolves the issue.

I think you have multiple adb server running, genymotion could be one of them, but also Xamarin - Visual studio for mac OS could be running an adb server, closing Visual studio worked for me

ADB server didn't ACK on macOS

I am getting this error since two days ago when I updated my Android Studio to the latest stable version 2.3; the full error message I am getting from Gradle Console is:
07:59:59 E/adb: error: could not install *smartsocket* listener: Address already in use
07:59:59 E/adb: ADB server didn't ACK
07:59:59 E/adb: * failed to start daemon *
07:59:59 E/adb: error: cannot connect to daemon
07:59:59 E/ddms: '/Users/USER_NAME/Library/Android/sdk/platform-tools/adb start
server' failed -- run manually if necessary
My attempts to solve the issue:
kill all adb processes and make sure no process is holding port 5037, adb kill-server (says * server not running * even in cases when adb is running), close Android Studio, delete ~/.android directory, run adb start-server (says * daemon not running. starting it now at tcp:5037 *; * daemon started successfully *, start Android Studio and run application, MAC throws error adb quit unexpectedly and gradle console shows same the error I posted above.
uninstalled and deleted all Android Studio stuff (except for projects directory), restarted MAC, installed fresh and latest android studio.
increased gradle vm ram org.gradle.jvmargs=-Xmx1536M in project gradle.properties
uninstalled antivirus and restarted the mac
Environment:
OS: MacOS Sierra 10.12.3
Android Studio: 2.3
buildToolsVersion: '25.0.0'
Android Debug Bridge version: 1.0.39

Address already in use means you have another instance of adb running.
Check your system variable $PATH and $ANDROID_HOME and local.properties file (of your project) and your .bash_profile . Make sure that all of these has same android sdk path. Then try restarting the adb server.
adb kill-server and adb start-server.

I read that you killed the adb, but as this answer says How to resolve the "ADB server didn't ACK" error? did you do that from the platform-tools folder? If your answer is yes, update the Android SDK to the lastest version via the SDK manager and update the $ANDROID_HOME
I hope it helps!

I usually find this issue occurring when I have two instances of ADB working, i.e when I have my Eclipse and Android studio running at the same time AND when they point to different SDK Manager(platform-tools folder) on the system. Try to search for what other IDE is using ADB, kill it in the Activity Monitor and run only one instance. Or my work around was to have only one SDK Manager and point both my IDEs to one platform-tools folder.
Hope that helps.

In my case, I had an old version of adb installed using brew cask. And while I updated my Android Studio to the latest, the adb was still pointing to the brew installed older version.
So after updating that version, using:
brew cask install android-platform-tools
And making sure that the adb itself was pointing to the new version, the errors went away.

Just write down platform-tools path (/Users/USER_NAME/Library/Android/sdk/platform-tools)
In the .bash_profile file, located at (/Users/USER_NAME/.bash_profile), like this :
export PATH="$PATH:/Users/USER_NAME/Library/Android/sdk/platform-tools"

React-Native, Android, Genymotion: ADB server didn't ACK

I am working with React-Native, Android, and Genymotion on Mac. When I run react-native run-android I get this lines at the end of the launch operation:
...
04:54:40 E/adb: error: could not install *smartsocket* listener: Address already in use
04:54:40 E/adb: ADB server didn't ACK
04:54:40 E/ddms: '/Users/paulbrie/Library/Android/sdk/platform-tools/adb,start-server' failed -- run manually if necessary
04:54:40 E/adb: * failed to start daemon *

:app:installDebug FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:installDebug'.
> com.android.builder.testing.api.DeviceException: Timeout getting device list.
...
However, adb devices returns this:
List of devices attached
192.168.59.101:5555 device
So far I've found no solution to run my app on the emulator. Has anyone encountered the same issue?
Thanks,
Paul

After more research I've realized that Genymotion uses by default its own adb.
I switched to my main adb (the same used by react-native) and it solved the issue. I guess that because Genymotion's adb was launched first I got the Address already in use error message.

I am using genymotion, but Paul's solution alone did not fix the error (for Mac).
I had to:
Update Android SDK to the latest version (24.4.1) via the SDK manager
Type android in the command line
In the SDK manager find the latest SDK tools and install.
Once installed the SDK path should update the new SDK location like below.
Then update the $ANDROID_HOME to use the new SDK
export ANDROID_HOME=/usr/local/Cellar/android-sdk/24.4.1_1
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
Confirm it has been added by viewing your path with echo $PATH
Then in genymotion do what #Paul says above and point genymotion ADB to use the same sdk

System: Windows 10
My issue: Setting Genymotion to point to the custom SDK didn't have any affect. I still received the:
Couldn't start project on Android: could not install smartsocket
listener: cannot bind to 127.0.0.1:5037: Only one usage of each socket
address (protocol/network address/port) is normally permitted. (10048)
could not read ok from ADB Server * failed to start daemon * error:
cannot connect to daemon
What I discovered was there was a difference in ADB versions being used throughout the system. Here is the command I used to find them:
where /r C:\ adb.exe
This produced the results:
C:\Program Files\Expo XDE\resources\app\node_modules\xdl\binaries\windows\adb\adb.exe
C:\Program Files\Genymobile\Genymotion\tools\adb.exe
C:\Users\kyle\AppData\Local\Android\Sdk\platform-tools\adb.exe
C:\Users\kyle\AppData\Local\Android\Sdk\platform-tools\adb backup\adb.exe
Navigating to each directory and running:
adb.exe version
Allowed me to see that Expo was running ADB version:
Android Debug Bridge version 1.0.36
Revision fd9e4d07b0f5-android
While Genymotion using the custom SDK had version (c:\Users\kyle\AppData\Local\Android\Sdk\platform-tools\adb.exe):
Android Debug Bridge version 1.0.39
Revision 3db08f2c6889-android
As a test I took the adb files (adb.exe, AdbWinApi.dll, AdbWinUsbApi.dll) from
c:\Users\kyle\AppData\Local\Android\Sdk\platform-tools\adb.exe
and placed them into a backup folder. I then moved the adb files located at
c:\Program Files\Expo XDE\resources\app\node_modules\xdl\binaries\windows\adb\adb.exe
into that same location. I killed adb with:
adb kill-server
which caused a restart of the adb server automatically due to having my Genymotion device already running. I hit the "Restart" button inside of the Expo XDE and it immediately began working. Here is the log where I hit the restart button at 1:13:04 AM:
12:45:53 AM
could not install *smartsocket* listener: cannot bind to 127.0.0.1:5037: Only one usage of each socket address (protocol/network address/port) is normally permitted. (10048)

Conclusion: Genymotion and Expo may need to use the same version of adb so that Expo can properly communicate with the simulated device. Pointing Genymotion to your android SDK location as well as ensuring Expo XDE has that same version will allow correct communication between devices. I moved the Expo XDE version to the SDK location, but you might be able to go the other way (take the sdk ADB files and place them in the Expo XDE resource location).
P.S. I've been all through the stackoverflow posts related to this issue. Just so you guys know my task manager shows three instances of adb.exe running. If you kill any of them they just come back.
Hope this helps /cheers

Maybe your adb versions are mismatching
Check:
adb version
Then:
cd /Path/to/Android/Sdk/platform-tools && ./adb version
If these two are different you have an error here, just remove adb from sys and copy the one that is in platform-tools to /usr/bin/

the adb version on your system is different from the adb version on the android sdk platform-tools .
Below suggestion is work for me for Linux operating system
check sys adb version run the below command
adb version
Android Debug Bridge version 1.0.39
check sdk adb version
cd /root/Android/Sdk/platform-tools
./adb version
Android Debug Bridge version 1.0.32
copy
rm /usr/bin/adb
[Note : the above command remove the existing adb then copy the adb from sdk/platform-tools directory ]
sudo cp /root/Android/Sdk/platform-tools/adb /usr/bin/adb
Then run the project using this command
react-native run-android

If want to keep your system clean, you can also use Genymotion without Android Studio:
Find Genymotion's copy of adb. On macOS this is normally /Applications/Genymotion.app/Contents/MacOS/tools/.
Add the Genymotion tools directory to your path - execute/add the line export PATH=/Applications/Genymotion.app/Contents/MacOS/tools/:$PATH to your ~/.bash_profile or ~/.bash_rc.
Make sure that you can run adb from your terminal.
(From https://docs.expo.io/versions/latest/workflow/genymotion)

I had the same thing while I tried to run from expo UI.
Did the same things, as described in answers, but app was not running.
When once tried run exp android from command line (in the project folder), application ran successfully and next times runs from Expo UI was successfully.

I had a similar issue.
First, I uninstalled the app.
Then, I pointed GenyMotion to the android sdk provided from Android Studio
Next, I ran "adb kill-server" into the terminal.
Finally, I re-ran "react-native run-android" and got a build success.

The steps worked for me are :
$ adb kill-server
$ adb start-server
$ cd android
$ ./gradlew clean
$ cd ..
$ react-native run-android

For Ubuntu
It works for me!!
check sys adb version
adb version
Android Debug Bridge version 1.0.39
2 check sdk adb version
cd /home/user_name/Android/sdk/platform-tools
./adb version
Android Debug Bridge version 1.0.32
copy
sudo cp /home/user_name/Android/sdk/platform-tools/adb /usr/local/bin
that's all! It will work now.

1.use custom sdk path in genymotion.(Suppose this one won't work means,Try to execute the second one)
2.Manually use this command to execute(SDK PATH/adb she
ll am start -n/Package name/MainActivity).
C:\Users\AppData\Local\Android\Sdk/platform-tools/adb she
ll am start -n com.example/com.example.ManiActivity
And try to run the application by using react-native run-android.

Same issue happened when I try to run my react-native project in Genymotion
For Linux ubuntu 20.04
Go to /home/mycomputer/Android/Sdk/platorm-tools
run $./adb version
just copy the adb path in /usr/bin
$ sudo cp /home/raik/Android/Sdk/platform-tools/adb /usr/bin
Then I can run my project in genymotion.
Note: In some Linux system may be copied to this path /usr/local/bin`

If someone is facing this issue in Windows with Android Studio emulator then just run following command in powershell or cmd:
taskkill /F /IM adb.exe
It should kill all the adb process instances and then you can Reload the app or Start the App on Android again via Expo CLI.

ADB not responding. You can wait more,or kill "adb.exe" process manually and click 'Restart'

I have installed Android Studio.
Then I have updated the Android SDK.
Now when I start Android Studio, this message pops up:
ADB not responding. You can wait more,or kill "adb.exe" process manually and click 'Restart'
The dialog has 3 options: Wait more, Restart and Cancel.
But all of them
gives me the same result, i.e. a message Waiting for ADB appears and I can't do anything with Android Studio.
I have to kill the program using windows task manager! I'm using windows 7.
Can anyone help me on this?

Go to
Tools > Android > (Uncheck) Enable ADB Integration
(if studio hangs/gets stuck end adb process manually)
then,
Tools > Android > (Check) Enable ADB Integration

On my macbook pro, i was occasionally getting this in Android Studio. The following resolved it for me:
Open up a Terminal and, instead of using 'adb kill-server', use this:
$ killall adb
wait a minute and it looks like Android Studio automatically restarts adb on it's own.

From the command prompt run the command adb kill-server. This will shutdown ADB and android studio or Eclipse if you were to use that, would show Waiting for ADB as you said.
Once ADB has shutdown down run adb start-server or run adb devices which will automatically start the adb service and show that your android emulator or development devices has successfully connected.

If you are suffering from "ADB not responding. If you’d like to retry, then please manually kill ‘adb’ and click ‘Restart’ or terminal appear Syntax error: “)” unexpected"
then perhaps you are using 32bit OS and platform-tools has updated up 23.1.
The solution is to go back to the platform-tools 23.0.1.
You can download the platform-tools 23.0.1 for Linux here , for windowns here and Mac here
After the download, go to your sdk location > platform-tools folder to delete old platform-tools in sdk and paste down into the downloaded one.
Woohooo ... it should work.
This is a bug with latest ADT.

For me, on Windows 7, killing the ADB server and restarting it via command line did not help. It would not start up successfully.
>adb kill-server
>adb start-server
* daemon not running. starting it now on port 5037 *
ADB server didn't ACK
* failed to start daemon *
So killing the adb.exe process via Task Manager was actually the easiest solution that case.

Check if any service is listening on port 5037, and kill it. You can use lsof for this:
$ lsof -i :5037
$ kill <PID Process>
Then try
$ adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
This solved my problem.

I ran into this problem and tried a number of solutions on my Mac without any success. I finally got to work with the commands below:
$ rm -rf ~/.android
$ killall adb
$ adb devices
Note that rm -rf ~/.android will remove any AVDs that you have configured, so don't take this step lightly. Personally I had to though and I'm not sure why. Hopefully this helps someone.

This issue could be because adb incompatibility with the newest version of the platform SDK.
Try the following:
If you are using Genymotion, manually set the Android SDK within Genymotion settings to your sdk path. Go to Genymotion -> settings -> ADB -> Use custom SDK Tools -> Browse and ender your local SDK path.
If you haverecently updated your platform-tools plugin version, revert back to 23.0.1.
Its a bug within ADB, one of the above must most likely be your solution.

I run netstat -nao | findstr 5037 in cmd.
As you see there is a process with id 3888. I kill it with taskkill /f /pid 3888
if you have more than one, kill all.
after that run adb with adb start-server, my adb run sucessfully.

1.if your phone system is over 4.2.2 , there will be
2.disconnect the USB and try again or restart your phone
3.After after all try , it didn't work. It may be a shortage power supply so try other usb interface on your computer.
I solved the problem doing the first step . anyway have try.

If you need to kill all adb processes on windows with one command, you can do it as follows:
taskkill /F /IM adb*

I had this problem and solved it by this way...
I had a app in my pc that used adb...
I tried to disable it but still my android studio's adb had problem
after unistall that application and problem solved.

I had the same problem. I have restarted ADB in any possible way, I have killed the process and restarted the PC with no results.
Then I found this plugin. Just download and install it in your Android Studio IDE. Under Tools -> Android you have a menu ADB Idea. Here you can kill, start, restart, clean ADB.

None of the above helped me completely. Although Oventoaster made me think. I had a couple of adb on my system. Removed them almost all.
I am running android studio on ubuntu 14.04 64 bit.
So I checked manually /home/xxxxx/Android/Sdk/platform-tools/adb
where xxxxx was my linux username
this gave
/home/xxxxx/Android/Sdk/platform-tools/adb: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
https://stackoverflow.com/a/27415749/4453157
solved it for me.

If the above CMD command option is not working and you cannot make it work in any other way then follow this below.
Click on below link
http://adbshell.com/downloads
and download the first link with name ADB Kits ( contains adb.exe and necessary .dll files).
After downloading replace these files with the ones in the path
Android/Sdk/platform-tools/
Now click on adb.exe and it will open cmd and will start the adb server.
Now it will detect the device and no problem. OOOOOllllaaaaa.....
If the Problem persists again then do the same... save the folder
somewhere.... just replace files... it will detect the device
automatically then

I had this problem on Windows 8, but I solved the problem by updating all of Android Studio's plugins with the SDK Manager, then restarting the computer.

An another one: you might want to avoid running Eclipse and Android Studio together, it helped me.

I had this problem on Windows 7. My situation is this through SDK Manager. I only download API 19 but I had not downloaded related Android SDK build-tools. So it occur this problem.
I went through SDK Manager download build-tools 19 to fix it. Hope to give you help.

Faced this issue on Mac:
I have tried different solution, But below works for me -
Uninstall "Vysor" plugin if you have installed for Chrome
Under Home folder > find .Android folder and move to trash
Goto, Android sdk > delete/move to trash platform-tools folder
Again install/download from Android SDK Manager
Open terminal -
adb kill-server
adb start-server
Check adb devices, It will work and display you all connected devices.
Hope it helps !

there seems to be about a million reasons this bug happens, but for me (running on ubuntu), it was openvpn running in the background that caused it.
I killed the openvpn service and no more issues.
