android studio platform-tools missing adb.exe

Today, I clicked some update when I launch Android Stodio. I forgot what it is. Then, I run some code when there is a error
"8:34 PM IllegalArgumentException: Unable to locate adb"
Then, I google for few hours and still cannot solve my problem. And I found that there is no "adb.exe" under my platform-tools folder.
Can someone help?
my os is Window 10.
I have tried uninstall Android Studio and install it back. It doesn't help.
Edit 1: After I re-install the platform-tools, I get back the adb.exe.But, I run my program again, it does the "ADB initialization", my adb.exe file lose again.

I am writing the solution which worked for me:
go to SDK Platform Tools;
download SDK Platform-Tools for Windows;
extract zip file and copy to \AppData\Local\Android\sdk\platform-tools.

Had the same problem. Solution was that Avast deleted the adb.exe.
Try adding the SDK folder to your antivirus whitelist.

What worked for me (after having AS 2.x and AS 3.x installed and trying to get Canary 3.1 to work):
Sometimes during an update/trying to sideload a new version of Android Studio, the updater/patcher screws up. It might delete adb after saying it will stop and update it, it might be fastboot or aapt ... whatever.
What works for me is to delete the whole sdk/platform-tools folder, restart AS and get it to redownload the entire platform tools package.
Then start AS again and go to File->Invalidate caches/restart.
If you have been updating Java, you might also want to ensure your JAVA_HOME is correct and that your AS project has been set to the correct JDK (project settings).

Yep, looks like LOTS of folks (way too many, shame on you, Google) have come up with a missing 'adb.exe' symptom. (In my case, I claim that it never got installed at all, during my Windows-10 bundled installation of Android Studio,
version 3.1.2.)
Ok, here's my recommended solution (which I borrowed and modified slightly from
this question): Android Studio SDK installer hangs indefinitely at Unzipping 'platform-tools/systrace/NOTICE'
The second(?) answer is essentially correct..."Dx Arout" boldly and correctly recommends:
(1) Delete platform-tools from this location C:\Users\AppData\Local\Android\Sdk
and he/she's got the right idea, to then launch Android Studio and try to get it to complain and offer to fix the problem for you...says to:
(2) Then restart Android Studio. After gradle build finish it will ask for installation of missing tools. just click there. It should work fine.
Well, no, not quite. It didn't ask me anything, because I didn't get any
errors from current proj's build. So, I had to 'kick-it-in-the-*ss', by
launching Tools -> SDK Manager, choosing the middle tab ('SDK Tools'), and going to an already-installed entry named 'Android SDK Build-Tools 28-rc2' (your exact version entry may be somewhat different). So, click on its checkbox, choose 'Show package details' checkbox (down in lower-right corner). I lit up ALL the package variants, and forced it to install them all. That may have been overkill, but voila...once that completed, 'adb' DID get installed, as confirmed
when I launched a debug run. (Down in the 'logcat' tab's log-message window, the two RED headings, finally turned to black and debugging was finally USEABLE!
Cheers...

it's easy just go to your sdk location
like C:\Users\User\AppData\Local\Android\Sdk
there was to folder namely
platform-tools and platform-tools.backup.
open platfrm-tools.backup and copy the adb.exe and paste it to plaform-tools folder and now open the android studio again.studio will run smoothly and without any error
Thank you

I also faced the issue.
The avast antivirus had moved the file adb.exe to the virus chest and that was the cause of the issue. I have resolved it by restoring the adb.exe from the virus chest of avast.

Re-installing Android SDK Platform-Tools worked for me.
Go to: Android Studio >> Tools >> SDK Manager >> Appearance & Behavior >>
System Settings >> Android SDK >> SDK Tools
Uncheck Android SDK Platform-Tools >> apply
Check Android SDK Platform-Tools >> apply

The problem is solved. The issue I have is I upgraded the SDK platform-tools to 25.0.6. But My SDK Build-Tools is 25.0.3. (25.0.6 is not yet provided) I guess the version did not match which cause this problem.
I downgrade my SDK platform-tools to 25.0.3 and it is working as usual.

adb.exe won't appear if antivirus is installed and we need to whitelist this.
Anti virus block this because as it find .exe file so it will block it.

system deleted that file from platform tools u just make another copy of platform tools and whenever your system deleted your " adb.exe ". you can copy it to sdk/ platform .
this is a temporary solution i installed Quick Heal but its doesn't solve my problem
adb.exe is virus file for that its detected as malware
**
Solution 2 :
** Copy your SDK FOLDER in System folder where antivirus dont take action on it .
**
Solution 3:
1.Download new copy of Platform Tools
2.paste it into SDK
3.right click on adb.exe and go to security tab
4.disable access of deleting by user system USERGROUP
Solution 4
copy sdk in appdata/local it will solve your problem permanent .
Thank You

no adb found. I had to delete the virtual device from AVD manager create another. now virtual device connected succesfully

"The following SDK components were not installed: sys-img-x86-addon-google_apis-google-22 and addon-google_apis-google-22"

I'm Windows 7 64-bit user and I got Android Studio problem after I update the latest version of Android Studio and SDK components..
The following SDK components were not installed: sys-img-x86-addon-google_apis-google-22 and addon-google_apis-google-22
Please help me to resolve this problem. Thank you.

I had the same issue when trying to upgrade Android Studio from 1.1 to 1.2 on Mac OS 10.10.
I solved the problem by selecting custom installation instead of standard. Also we need to select the Android SDK Platform (Lollipop 5.1).

Choose the new UI Design >> next
Just try to cancel the "Downloading Components" from upper right
corner 'X' button.
A dialog box will appear then click OK (wait a bit for first time
launch)

I uninstall Only Android studio (keep the SDK and Emulator) and then reinstall it just android studio. took me 2 minutes and my android studio work again.

I had this same problem, but I'm a Linux user.
I resolved the problem by reattempting the installation with adminstrator privileges. [For those Linux users reading this, I ran studio.sh with sudo.]

I just click 'Retry' and it's ok! Also run on Win7 64-bit.

TRY BELOW SOLUTIONS.
SOLUTION 1:
-> Run Android Studio as Administrator (this is only required for first run or when any issues arise due to automatic updates on any run in future).
Though it shows API 23 is or any other updates are not installed (and wouldn't show any 'Retry' button), BUT still the download and installation of rest of the updates would proceed (you can see the download progress incrementing even after seeing the above errors). So, DO NOT ABORT the operation.
-> At the end of installation (after rest of successful updates are installed) it would this time display the "Retry" button to retry installation for API 23 or any other versions which had failed earlier. Then click the "Retry" button, it would work this time.
This would resolve your issue with successful installation.
-> Next time onward no need to run Android studio as Administrator, unless it does any automatic updates and shows similar issues.
SOLUTION 2:
-> Alternative approach is to install any updates (which ever failed in earlier attempt) from Android SDK Manager first and then later launch Android Studio (which would not need any check for updates and any additional installations).
To install any features or updates, run Android SDK manager as administrator (run as administrator is not mandatory for this but preferred to avoid any permissions related issues) and check the required options and proceed with the installation without any issues.
SOLUTION 3:
-> If still your issue is not resolved, then try the proxy solution as suggested by others or check your internet connectivity if it's working properly or not.
*Any of the above solutions should resolve your issues.

go to c->users->[Your user account]-> remove android 1.2 and restart the android studio
when it ask to import select first radio button which is import setting from previous config
there you go fixed

I am using Windows 7 Professional and I was having same problem #Bayu Mohammad Lufty not worked for me.
I simply delete .AndroidStudio1.2 from my C:\Users\UserName\ and restart my Android studio again.
It open Android Studio perfectly!
It configured everything again in next start :)

I'm a MacOS user.
I solved it by uninstalling Android Studio and reinstalling it again.
If you want to try this link helped me a lot.
Uninstall Android Studio MacOS (terminal)

When you are installing Android Studio, under Install type do not use standard setting, use custom setting instead, and check all the option boxes in the next step.

i have solve my same problem
i update my android studio, and i choose not to import my setting from my previous version than that problem appear.
than i realize that i have 2 AndroidStudio folder on my windows account (.AndroidStudio and .AndroidStudio1.2) and on my new .AndroidStudio1.2 folder there are no other.xml file.
than i copy other.xml file from C:\Users\my windows account name.AndroidStudio\config\options to C:\Users\my windows account name.AndroidStudio1.2\config\options
and that how i solve my problem.

I'm using UBUNTU and I got this same error. I restarted the set up using sudo and did a custom install. This solved my problem!
--More Specific--
re-installed using # sudo ./studio.sh
then I made sure to click "Custom Install"
then I made sure all packages were selected.
And I got this message Android virtual device Nexus_5_API_22_x86 was successfully created

I just run:
C:\Users[Username]\AppData\Local\Android\sdk\SDK Manager.exe
Install SDK Platform Android M Preview
And run Android Studio again.
It's working for me :D

When this error occured I first clicked retry for few times and waited for 2 minutes and clicked 'retry' then it installed without any error.(for 2 minutes I was searching to solve this problem online).

I was getting an "out of space" error, which left me scratching my head as I had plenty of disk space, until I realized that it ran out of space on /tmp, which on Arch Linux is mounted on a tmpfs with a size limit.

Updating Android tools inside of SDK Manager automatically restarts my machine

Here is what's going on... It doesn't matter if I'm in Eclipse or manually launch SDK Manager. Once I'm in the Android SDK Manager I have packages selected and I click Install x packages... I accept the License agreement then click Install. It is then my computer restarts itself before it downloads and installs anything. It restarts before I can see any error messages. It does this every single time. I have re-downloaded everything and tried it from scratch, but I still get it. Why is it doing this and how can I prevent it?!

Since nobody on here could help me I figured it out. Here's what I did. First, I gave all permissions and took away read only attributes for the folder sdk [it may be named something different on your system] I then created a copy of the tools folder and named it tools 2. I opened a command prompt using administrator and use the command "android.bat avd manager" and i was able to update my sdk tools and all without any issues. Thank you me.

Can't update Android SDK tools to rev13

When I try to update my SDK to the latest version, i get the following error:
A Folder failed to be moved. On windows this typically means that a program is using that folder (for example Windows Explorer or your anti-virus software.) Please momentarily deactivate your anti-virus software or close any running programs that may be accessing the directory 'C:\adt\android-sdk\tools'. When ready, press YES to try again.
I checked with Process Explorer what processes use that directory and, surprise surprise, it's the SDK Manager that I use for the update.
Has anyone solved this?

I was also facing the same kind of error when i was trying to installing SDK, later on i found that there is a Kaspersky anti-virus installed in my machine and due to it, android is giving me this error.
Once i have paused the Kaspersky security service then i was successful to download the SDK and installation for the same.
So my clue is you should stop any antivirus service.

This problem was resolved in Android SDK Tools rev14.

Error received when updating the SDK with the SDK Manager

I'm completely frustrated with the Android SDK Manager.
I'm running Win 7 Home edition and have the SDK installed in its own top level directory on my D:\ drive.
When I run SDK Setup.exe from the command line (and I've even opened the prompt as an administrator), I get an error when trying to update the packages.
The SDK manager is telling me that I need to install the SDK Tools rev 7. But when I accept the license, I get an error message stating:
"A folder failed to be renamed or removed" yada yada yada. The Installing Archives window says "Failed to rename directory D:\android-sdk-windows\tools to D:\android-sdk-windows\temp\ToolPackage.old01."
I looked here for help:
http://groups.google.com/group/android-developers/browse_thread/thread/4b784f3eb1e096fd/ecadfb28ce5daf5f?lnk=gst&q=cannot+rename+folder#ecadfb28ce5daf5f
but the content there didn't help.
I DO have my antivirus (AVG) disabled.
I DO NOT have any other programs running -- just the command prompt to launch the SDK Manager.
I have even given the everyone group, for the D:\android-sdk-windows\ folder, full control.
I tried to rename the tools directory before starting the SDK Manager but then I get an error that a batch file cannot be found when I try to launch SDK Setup.exe. Grrrr.
None of this works.
Suggestions how to get the package to update without error are greatly appreciated.
Thanks!

A simple thing,
There will be zipped file after this error has been occured. Meaning that Updated tools got store as
tools_r16-windows.zip in C:\Program Files\Android\android-sdk\temp
Just extract it and copy it in our tools folder
C:\Program Files\Android\android-sdk\tools
Enjoy:)
I think ths might help. Please give your comments!!

If you get this error while using Eclipse on a 64-bit Window 7 (might 32-bit as well), exit Eclipse, go to your SDK folder and run "SDK Manager.exe" as Administrator. In my case, Eclipse turned out to be what locked the folder in the first place.

# Stratos - Thank you for your instructions, they worked for me.
Go to Android\
android-sdk\
tools\
Delete "source.properties" (Right click - delete)
Open SDK Manager and update
And everyone lived happily ever after...

You can't use 64 bit java or 64 bit eclipse. That's almost certainly your problem.

Had the same problem. For me it was a bit circular, the SDK manager had a hold at source.properties and closing the process terminated the update. I deleted android-sdk\tools\source.properties before running the SDK manager and it all worked. Oh and I was not updating through Eclipse so it is not an Eclipse problem.

I can't vote yet, or I would have voted for Stratos.
I had already disabled my Norton antivirus (after reading other posts).
Removing the source.properties file helped.
Don't forget to run SDK manager with admin rights if not already.

There is another simple way:
When the SDK asks to install the Java SE JDK press back and then press next. This time it will detect the installed JDK. I solved this problem twice with this method

Use Unlocker to unlock the tools folder.
Right click on tools folder -> Unlocker. This way you don't even have to find out what is locking the folder...

Start task manage and end Adb.exe. Thisnisnthe program that has a hold on the folder. Rename the tools folder to some other name eg. 'toolsold'. Then extract the zip file containing the new tools folder. Rerun the updates and it should be detected as updated and it should proceed with the outstanding tasks.

Run SDK manager as Administrator, this fixed for me
