there you can clearly see which platform tool is missing , then just install that and your adb will start working properly.

For anyone who is still running into this issue. I had a similar problem where I could see my device from adb on the command line using <code>adb devices</code> but Android Studio would not recognize when I had a device attached and would throw either:

<ul>
<li><code>Unable to locate adb within SDK</code> or</li>
<li><code>Unable to obtain result of 'adb version'</code>

I had tried start/stops of adb, uninstalls, of platform-tools, and more. What I found was that inside my <code>C:\Users\&lt;UserName&gt;\AppData\Local\Android</code> folder I had multiple sdk folders. I performed the following: 

<ol>
<li>Unistall Platform-Tools using Android Studio's SDK Manager</li>
<li>Deleted all <code>platform-tools\</code> directories within each <code>C:\Users\&lt;UserName&gt;\AppData\Local\Android\sdk*</code> directory</li>
<li>Reinstalled Platform-Tools using Android Studio's SDK Manager</li>
</ol></li>
</ul>

Hope this helps someone someday with their issue.

even after downloading specific required file or everything, we could face file execution error. 

a file execution fail could be due to following reasons: 
1. user permission/s (inheritance manhandled). 
2. corrupt file. 
3. file being accessed by another application at the same time. 
4. file being locked by anti-malware / anti-virus software. 

strangely my antivirus detected adb, avd and jndispatch.dll files as unclean files and dumped them to its vault. 

i had to restore them from AVG vault.
configure AVG to ignore (add folder to exception list) folder of AndroidStudio and other required folder.

if you are without antivirus and still facing this problem, remember that windows 7 and above have inbuilt 'windows defender'. see whether this fellow is doing the same thing. put your folder in antivirus 'exclusion' list as the vendor is trusted world wide.

this same answer would go to '<a href="https://stackoverflow.com/q/26355645/2173890">Error in launching AVD with AMD processor</a>'. i don't have enough reputation to answer this question there and there.

I had this issue with <code>Android Studio 3</code>, the SDK manager somehow didn't include the full tools in platform-tools folder so I had to download it manually from:

While all these answer might have been correct in my scenario it didn't work. It all started when i uninstalled 2.* android studio version after getting 3.0rc1. But that screw up things and started getting this error. After that i did followed majority of these steps and none of them worked. While analyzing SDK directory i noticed that i have two platform tools folder. The .backup had adb.exe where as the other one didn't. I just copied the .backup files in the other platform-tool folder and it fixed my issue.

It's worked for me (Android Studio 3.1.3):

1. Make sure that 'Android SDK Platform-Tools' is installed:

<blockquote>
 Tools > SDK Manager > SDK Tools (Tab)
</blockquote>

2. Copy path of 'adb.exe' file. Usually here:

<blockquote>
 C:\Users\Username\AppData\Local\Android\Sdk\platform-tools
</blockquote>

3. Open Enviroment Variables in Windows:

<blockquote>
 'Window + R' > and type 'SystemPropertiesAdvanced'> Enviroment
 Variables...
</blockquote>

4. Create new system variable with name 'PATH' and value of your adb.exe path like that 'C:\Users\Username\AppData\Local\Android\Sdk\platform-tools'

I struggled with this for a while. Tried to install/uninstall various packages under the SDK Manager without success. I even deleted Android Studio and reinstall it, it did not help.

I am running Android Studio 3.3 on OS X 10.14.2. At the end I tried the following:

<pre><code>rm -rf Library/Android/sdk
</code></pre>

This removed the whole sdk folder. You should run this command on your home directory in terminal. (it is the default location when you open it)

I then started Android Studio and it could not find the sdk. So it prompted me to download it. I downloaded a fresh SDK and everything was working normally.

It might be an overkill but it worked.

If you have an antivirus (such as AVG), you can take the file out of quarantine.

<img src="https://i.stack.imgur.com/xtunZ.png" width="400" height="400">

Click Menu > Quarantine > Check box next to the adb.exe file > Arrow next to delete > Restore

But sometimes, the file will keep reappearing in the quarantine. The way to solve this is by clicking <code>Restore and add exception</code>, or by going to Menu > Setting > General > Exceptions > And adding something like this: <code>C:\Users\Johndoe\AppData\Local\Android\Sdk\platform-tools\</code>

Other antiviruses have similar equivalents of a "quarantine" that the APK file may be in.

Got the same problem. MacOS, Android Studio 3.6.1, SDK Android 10.0.

This is the directory where Android studio is looking for adb binary:

<pre><code>$ cd ~/Library/Android/sdk/platform-tools/
➜ platform-tools $ ls
package.xml platform-tools signing_request_for.3232179dce22d8a6332018729026ed39f5d5cd0b.1585090071041.platform-tools_r29.0.6-darwin.filelist

However, the binary is in the one directory deeper:

<pre><code>➜ platform-tools $ ls platform-tools
adb dmtracedump etc1tool hprof-conv make_f2fs mke2fs.conf sload_f2fs sqlite3
api e2fsdroid fastboot lib64 mke2fs NOTICE.txt source.properties systrace
</code></pre>

Simply make a soft link to current directory:

<pre><code>➜ platform-tools $ ln -s platform-tools/adb ./
➜ platform-tools $ ls
adb platform-tools
package.xml signing_request_for.3232179dce22d8a6332018729026ed39f5d5cd0b.1585090071041.platform-tools_r29.0.6-darwin.filelist
</code></pre>

This did trick for me.

P.S. Adding it to the PATH does not help, I can of course run it in terminal then, but Android Studio does not pick up PATH variable from .zshrc in MacOS.

Finally after several hours of investigation I think I have another solution for everyone having issues with AVD Manager "Unable to locate adb".

I know we have the setting for the SDK in File -> Settings -> Appearance &amp; Behavior -> System Settings -> Android SDK. This it seems is not enough! It appears that Android Studio (at least the new version 4) does not give projects a default SDK, despite the above setting.

So, you also (for each project) need to go to File -> Project Structure -> Project Settings -> Project, and select the Project SDK, which is set to [No SDK] by default.

If there's nothing in the drop-down box, then select New, select Android SDK, and navigate to your Android SDK location (normally C:\Users[username]\AppData\Local\Android\Sdk on Windows). You will then be able to select the Android API xx Platform. You now should not get this annoying adb error.

After trying all of the above (and more), I googled how to reset Android Studio, and that eventually worked for this!
On MAC delete this folder:
~/Library/Application Support/Google/AndroidStudio4.1
I then checked the adb in terminal by running adb command, and it was showing up as it should.

When I then ran my react-native project with yarn start and yarn android, it first failed, but running it a second time worked.

<blockquote>
It worked for me in this way
</blockquote>
open your android studio First, and go to SDK manager :
<a href="https://i.stack.imgur.com/KMu0M.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/KMu0M.png" alt="enter image description here" /></a>
and Copy your Android SDK location then open PowerShell on your windows
and go to that folder like :
<pre><code>cd C:\Users\YOURUSERNAME\AppData\Local\Android\Sdk
</code></pre>
then go to platform-tools folder:
<pre><code>cd platform-tools
</code></pre>
and then start ADB like this:
<pre><code>.\adb.exe
</code></pre>
you can also check if there is any adb.exe by <code>ls</code> or <code>dir</code> in windows command line
<blockquote>
if there isn't any platform tools you should first install it and then
paste it into that directory that I've mentioned earlier
</blockquote>
you can download platform-tool(adb) from here:
<a href="https://developer.android.com/studio/releases/platform-tools" rel="nofollow noreferrer">https://developer.android.com/studio/releases/platform-tools</a>

Does anyone know what this means? When I click the &quot;run&quot; button on my simulator I get this message.
<blockquote>
Throwable: Unable to locate adb within SDK
</blockquote>
I am running the latest version, <code>0.8.14</code>.
