When i m trying to run app in emulator or in real device everytime it throws an exception
Unable to connect to adb. Verify that your localhost entry is pointing to ip4 or ip6 respectively Android
For getting solution i dig google and tried the solution using
adb tcpip 5555
adb connect 127.0.0.1:5555
But every time it catch the same exception.
daemon not running; starting now at tcp:5037
adb F 05-03 12:32:21 9776 7156 main.cpp:45] cannot open C:\Users\admin\AppData\Local\Temp\adb.log: Permission denied
This application has requested the Runtime to terminate it in an unusual way.
Advanced help would be appreciated!
Open command Prompt use following commands
adb kill-server
adb start-server
adb devices // it will shows the device id if its connect success
if not showing the device restart android studio and mobile then execute the command again it will work
Finally i found an answer.
There was my silly mistake. While i was set JAVA_HOME path by
C:\Program Files (x86)\Java\jre1.8.0_211\bin
So just i needed to remove \bin. The correct path is
C:\Program Files (x86)\Java\jre1.8.0_211
Further i started Android Studio as Run as Administrator.
First, try running adb.exe in at the sdk/platform-tools. If it's not working then probably your adb.exe is broken. Then you need to download the sdk again or you can replace the platform-tools folder from some another pc. I also face that problem with Android Studio 3.4.
I'm having problems starting my adb in eclipse and looked for all answers here for this issue such as stopping an antivirus called COMODO Defense+ which i actually don't have or copying files from \platform-tools to \tool........ but non worked.
I get the following erros when ever reseting adb or trying to run my android application:
[2014-04-07 16:58:55 - Trucks] The connection to adb is down, and a severe error has occured.
[2014-04-07 16:58:55 - Trucks] You must restart adb and Eclipse.
[2014-04-07 16:58:55 - Trucks] Please ensure that adb is correctly located at 'C:\Users\........\adb.exe' and can be executed.
and the adb is directed in this directory for sure.
Also i get pop messages:
Adb failed to restart!
Make sure the plugin is properly configured.
and
Attempting to restart adb, but version check failed!
I had a randsome virus a while ago that locked my files, but i have unlocked them all now, could the virus had done something with eclipse that changed something related to the Adb?
I've had this problem before
at first kill adb.exe from task manager;
then turn off antivirus firewall - (or Put adb.exe in extensions).
at last start adb.exe.
try it , i hope it work;
When I try to test my Android application with an android emulator as always I now suddenly get an error message. I'm working with Windows 8. So far I tried the following things which unfortunately could not solve the problem:
reinstalling eclipse with android adt
reinstalling java
installing "android studios" first solved the problem but after one day mysteriously also here adb, stopped working with the error message given in the title " ADB not responding ...
furthermore I unsuccessfully tried out some advice from Mr. Google:
Stopping adb.exe via task-manager and restarting eclipse / android studios
"adb kill-server" then "start-server" via command prompt
setting the path to adb.exe as an environment variable
switching off any antivirus or firewall
starting the IDEs as an administrator
updating the IDEs
The only thing I can remember doing which may have destroyed adb on my computer for all times: I connected my motorola smartphone to my laptop and installed the motorola usb drivers but as I said the adb also won't work with the emulator.
Any help would be kindly appreciated. The issue bothers me for more than an entire day now. Maybe someone had similar problems on Windows 8 ?
On OSX helped:
Close Android Studio
Kill all processess using 5037 port
sudo lsof -i |grep 5037
sudo kill PID_NUMBER
Run adb devices from console
adb devices
Meanwhile the emulator is working again. I cannot definetly say what solved the problem. What It could be a combination of two things:
Deleting the hidden ".android" folder under C:\Users...
(Probably there was some malfunctioning automatically created code)
Deleting and recreating the Path variable to the folder with adb.exe ( ...\sdk\platform-tools\;)
Finally it could be a Windows 8 issue which I don't understand.
Try this,
Open a command prompt with administration permission and type
netsh interface tcp set global autotuninglevel=disabled
This worked for me
Edit: Windows only
Kill the adb.exe with a command prompt. Open a command prompt were your adb.exe is located and type
adb kill-server
Maybe HTTP Proxy blocked the localhost 127.0.0.1:5037
If you have config the HTTP Proxy, make sure to exclude the localhost like picture below
Also, port can also be blocked by the firewall and anti-virus firewall, please notice as well.
Try this,
at the prompt try adb kill-server
Start one of your AVDs
at the prompt try adb root
The prompt should say adbd is already running as root.
That should fix it.
In case it helps anyone else, for me the problem was related with the USB hub that the tablet was plugged into on the computer (unplugging the webcam which was in use fixed it).
I got the same error. Don't worry. I have an solution. Go to Task Manager. Kill the process called adb.exe. You will find 2 or 3 processes. Kill all of them. You are done. It will work.
I have the same problems. Verify port 5037 is free and ports 5555 to 5585 are available and never used by another process.
"ADB server sets up connections to all running emulator/device instances. It locates emulator/device instances by scanning odd-numbered ports in the range 5555 to 5585"
FROM: http://developer.android.com/tools/help/adb.html
To find out which process is listening on a port on Windows yo can use:
C:> netstat -an -o
FROM: How can you find out which process is listening on a port on Windows?
I had the same problem, here is my simple fix:
-Go to task manager in windows, look for adb.exe, and kill it
-Go to command prompt, and tap adb devices ==> it will automaticaly start adb daemon
I finally just restarted the computer, and that solved the issue for me.
Uninstall HTC Sync. Or disable it somehow.
Try to open adb from command prompt from directory location as <sdk>\platform-tools,
If adb file is missing try to re-install Android SDK with latest version,
And try to run again..
I think issues will solved, by this procedure.
I saw this on a Mac OS X.
I shut down Android Studio and ran adb get-state in the terminal. When I started Android Studio back up, the warning had gone away.
BTW, I did just try restarting Android Studio without any luck. I am sure a restart of OS would have fixed it too.
The same thing with the Asus Sync utility (with the both our Transformer's 700 and 701).
I think there is a USB-port conflict between ABD driver and Sync utility.
Exit from Sync utility resolve the problem.
Looks like this could be caused by a bunch of different issues. This just happened to me because I had my android phone device plugged in for USB debugging, then after a few hours (and multiple android studio/phpstorm restarts) I had to do unplug the device manually. Things started working again after unplugging.
I have faced this problem few days ago. When I opened my task manager it showing me two adb runnig. It may be because of I am using mobogenie for connecting my android phone for debugging application. This problem is because of moboginie and adt port conflict. then I have followed following procedure to sort out this issue.
!) close eclipse
2) Go to task manager and kill all adb processes.
3) Now go to platform-tools in android sdk
4)press shift+right click mouse and select "open command window here" option
5) type
adb kill-server
adb start-server
6)if server sucessfully started then start eclipse and then connect your phone
(Remember dont connect your phone before starting eclipse)
Following works for me every time:
go to File->Invalidate Caches/Restart
select Invalidate and Restart
And, You are good to go.
After updating the SDK, Eclipse shows this error:
ADB server didn't ACK, failed to start daemon.
When I run an Android application, it gives me the following:
Please ensure that adb is correctly located at 'D:\android-sdk-windows\platform-tools\adb.exe' and can be executed.
How can I fix this problem?
Thanks, #jowett, I have solved my same problem, doing these steps
Step 1:
CTRL+Shift+Esc to open the task manager, which has adb.exe process and end (kill) that process
Step 2:
Now, close the eclipse, which is currently running on my computer.
Step 3:
Again, restart eclipse then solved that problem.
For those using OS X
killall adb
For those using Windows
adb kill-server
should do the trick.
I met same problem, though I didn't what caused this. Whatever, i find some clues and fixed finally.
When I open SDK and AVD manager, but find the AVD version(2.3.3) is not same with android lib version(2.3). So I create a new AVD with 2.3.
I fixed it by the following steps:
1. Open windows task manager and kill adb.exe process.
2. Close eclipse and restart it. Then it works.
Hope it helps.
Command prompt (cmd.exe):
netstat -aon | findstr 5037
Find the process id of 0.0.0.0:
Make sure it's adb.exe:
tasklist | findstr 1980
Kill this process:
taskkill /f /t /im adb.exe
Get ADB back to normal:
Credit: blog post *Android ADB server didn't ACK failed to start daemon*
These symptoms occur if you are using the Genymotion emulator (on Windows or Linux) at the same time as Android Studio:
adb server is out of date. killing...
ADB server didn't ACK
* failed to start daemon *
Genymotion includes its own copy of adb, which interferes with the one bundled in the Android SDK.
The easiest way to fix seems to be to update your Genymotion Settings so it uses the same ADB as your Android SDK:
Just check the "Use custom Android SDK tools" option and enter your desired location.
ADB will often fail if there is a newline in adb_usb.ini. Remove it, restart it, and that will often solve the problem (at least for me anyway).
If you are using a sync application for the device, it could also be because there are other apps using the same 5037 port. Shut down all services running on port 5037 and try starting ADB.
To check if any application is using port 5037, use this:
netstat -a -n -o |findstr "5037"
Get the PID of the application.
Use Process Explorer to find the Process and exit it.
Now use adb start-server or adb get-state to start/check the ADB server status.
I faced the issue when I used the Snappea / Wandoujia Sync application.
I caused this problem by entering an extra blank line at the end of ~/.android/adb_usb.ini
(Removing the extra blank line fixed the problem)
We can solve this issue so easily.
Open a command prompt, and do cd <platform-tools directory>
Run command adb kill-server
Open Windows Task manager and check whether adb is still running. If it is, just kill adb.exe
Run command adb start-server in the command prompt
I have solved my first question: Open Eclipse, open the SDK Manager, and choose the device to open.
Or you can open the SDK directory. Open the SDK Manager, and then choose the device to open
2: Close Eclipse, and then open it.
Make sure USB debugging on your phone is turned on. ADB kill-server and ADB start-server is not the problem.

I've already up-voted another answer here to this question, but just in case anyone was wondering, you don't need to restart Eclipse to get ADB running again. Just open a shell and run the command:
adb start-server
If you haven't set the path to ADB in your system properties then you must first go to the directory in which ADB exists(in Android\android-sdk\platform-tools....I'm running Windows, I don't know how the mac people do things).
Run over to sysinternals.com and pick up TCPVIEW and PROCESS EXPLORER, if you don't have them installed already.
For some reason, the ADB daemon is terminating before the close socket exchange is complete. If you run (from the command prompt) "NETSTAT -o", you will see the socket (generally 5037) in CLOSE_WAIT state and the owning process number. Process Explorer won't show that process ID (the daemon terminated), and the process called adb.exe (which opened the socket) will be gone. (If adb.exe if found, try killing the task and see if things get cleaned up.)
Using TCPVIEW, locate the hung socket. The process name column will show the associated process can not be found. Right click, and select "Close Connection". The socket is now closed, and the adb daemon should be able to start.
I had a similar issue. Killing an existing instance of the ADB process from Task Manager did not work for me.
Just few days back, I had tried to install MIPS SDK and ADT-17 earlier and Eclipse gave me the error, and I did not fix that issue.
So, now, when I got this ADB server didn't ACK, failed to start daemon... issue, I executed 'Check for Updates' in the Eclipse Help menu item.
There were no updates available, but at least 'ADB server did not ACK' error disappeared.
I hope this might help in a few cases.
Type ./adb nodaemon server in a terminal.
If it returns Invalid content in adb_usb.ini, then there is a problem with your adb_usb.ini file in the .android folder.
Open adb_usb.ini and erase its contents. Then restart the server...it worked for me.
Check for the path of the Android directory. It should not contain spaces, etc.
Also check if the plugin has been properly configured in Eclipse → Preferences.
In my case I had everything checked multiple times, but it was still not working. I was about to reinstall everything, but I came upon an answer on this site (some other post).
Do check your antivirus. It may be blocking the ports of adb.exe or emulator programs, etc. That solved the problem in my case.
In addition to #Bastet's solution:
Actually we have to kill the process using the address 0.0.0.0:0. That's why for most of the people killing adb.exe from Task Manager was working (in my case I was not able to see it even in Task Manager).
Following the #Bastet steps, I found out that some other process was using this address. I went ahead to kill it, and it gave me ACCESS DENIED as Error.
So using the tasklist | findstr **** I found out the name of the process and killed it from Task Manager.
Thereafter it started working.
In my case bas_daemon and bas_helper were using this address both of which corresponds to MOBOROBO.
I had the same problem. But there was no process of adb on my laptop. I just log out and log in to my account, and it's resolved...
ADB could start from CMD windows after that.
The best and the most efficient way without restarting any device or software is:
Run the following:
adt-bundle-windows-x86_64\sdk\platform-tools\adb.exe
And one more thing.. ADB is a self-dependent thing. You cannot do anything until unless it wants itself to work. There is one more way which I found out: Leave the device connected for 5-6 minutes and wait. Soon the device gets connected and tries to launch.
This didn't start happening for me until I rooted my Samsung Galaxy S III phone (following the xda-developer forum guide).
It happens pretty randomly, but it's definitely occurring while running Eclipse.
Killing the adb.exe process and restarting it solves the problem.
Look at the antivirus or firewall... Does any of that block you from access... In k7 antivirus I turned off system monitor, and it does works for me...
Linux/Ubuntu users this might also be the case.... i had an android emulator running and I had to kill that. To do that do the following
lsof -i :5307
(use sudo if needed)
Note the pid in the result of above command. Then
kill -9 <pid_from_above>
then go ahead with
adb shell
I had to allow adb.exe to access my network in my firewall.
Killing Eclipse and then rebooting did not help me. I added the Android tool to the PATH variables, started Task Manager and killed adb.exe.
I restarted Eclipse, and then it worked.
This question already has answers here:
Eclipse error "ADB server didn't ACK, failed to start daemon"
(23 answers)
Closed 4 years ago.
I am a Android newbie. I guess I might be doing something stupid here. I have started the Virtual Device and I see that adbd daemon is running from the Terminal Emulator. When I run adb devices I get the following error:
C:\Program Files\Android\android-sdk\tools>adb devices
* daemon not running. starting it now on port 5037 *
ADB server didn't ACK
* failed to start daemon *
error: cannot connect to daemon
No other process is using port 5037. What am I doing wrong? Here are the packages I have installed -
1) Android SDK Tools, revision 10
2) Android SDK Platform-Tools, revision 3
3) SDK Platform Android 2.3.3, API 10, revision 1
This will occur normally,if abd is not able to launch properly and didn't exit when adb kill-server is executed.
So if in Windows
1. Go to Task Manager (CTRL+ALT+DEL)
2.look for adb.exe and end the process.
Now restart the emulator ,should work properly.
additionally you can close and launch the development environment also (eg: Eclipse or NetBeans).
I suspect the problem is cause of many adb instances (in windows) , i usually face this problem cause i don't turn off my system so the adb process may not end properly.
So open task manager choose Process tab just search for adb.exe, right click on it and choose End Process Tree rather than just End Process
Had the same problem, it seems that my security solution was blocking adb.exe
this is not the right folder for adb : lately adb has moved from /tools to /platform-tools in the sdk folder.
Seems like the security program is blocking adb.exe, so go to the adb file path and open adb's properties, then check the Run this program as administrator setting.
In my case the process adb.exe starts when i connect the phone, and then when I adb devices then I have your problem, and killing the process does not help it is resurrecting like a stubborn zombie, as long as the phone is connected.
so my solution was to disconnect the phone, then kill adb.exe process, then start it by adb devices and connect the phone
After that when i command adb devices i ma getting the same prompt about killing adb out of date, but this time on the second line is * daemon started sucessfully*
win xp
htc sensation
the new eclipse adt sdk bundle from google so i suppose up to date.
I found there was a process call "Tadb.exe" in Windows Task Manager.
I guess Tadb.exe is a similiar adb application of Tencent. Because I got an alert of "android device detected by QQ" after I install the last version of Tencent QQ2013 Beta5 (6970) yesterday.
After I killed the Tadb.exe, the original adb.exe of Android SDK works again.
You can see the detailed proecss to solve this problem here:
adb cannot run, adb server is out of date
I turned off the Windows Firewall and its working like magic. I am connected to the Internet through WiFi. If you are not behind a proxy and are still unable to access the Internet through a wireless link via the emulator, go to Device Manager and disable your LAN card.
As I have tried as follow by combining omni.present's method , and finally emulator works fine.
firstly I stop adb.exe process in the task manager
then I stop and start eclipse
The fundamental reason is because the 5037 port on your machine to be occupied by a process, not only Android devices can not use adb connection ios device not use iTunes.
Can query process and close it, netstat / a / o maybe can help you to take up to 5037 ports.
To windows7 the LogsAndAlerts service will occupy port 5037.
