unable to connect to adb.check the event log for a possible issue, verify that localhost entry is pointing to 127.0.0.1 or:: 1 for ipv4 or ipv6
Tried adb kill-server, restart, invalidate restart nothing works.
Same issue reported over here https://issuetracker.google.com/issues/130791561
Note: I have not added any file or anything in studio, it's fresh installed Studio after format a full system still issue is there.
Replace your platform-tools with this one and delete the other one.

I was also facing this issue in android Studio 3.4 version, but now I have fixed it , if you are using windows then follow these steps:
Download Platform tools from here
https://dl.google.com/android/repository/platform-tools_r26.0.0-windows.zip
Extract downloaded zip file
Go To location "C:\Users\your_computer_user_name\AppData\Local\Android\Sdk" and Delete "Platform tools" folder
Copy and Paste, downloaded platform tool folder to above location
Now Go to your android studio and Rebuild your project Then run.
For Mac Users, follow these simple steps :
Just simply Navigate to Tools > SDK Manager> Android SDK>, then click on the Tab of SDK Tools, then look for Android SDK Platform-tools and update it.
Then the last step, Invalidate cache and restart your IDE, after that, then finally you restart your Mac. (Sometimes it's this step is unnecessary)
It will work out successfully.
Solution for Linux Users.
System info: Linux Mint Cinnamon 19.1 , Android Studio 3.4.1
Issue description: Problem with platform tools.
Solution: Remove the folder manually and update SDK tools through Android Studio.
Step 1: Go to your Android SDK installation folder. By default under your home directory. Choose platform-tools and simply delete. (/home//Android/SDK)
Step 2: Open Android Studio and go to SDK Tools. (File -> Settings -> Appearance & Behaviour -> System Settings -> Android SDK -> SDK Tools) By the moment you should be able to see Android SDK Platform Tools line unchecked.
Step 3: Put a check to install Platform Tools and press OK. Notice it'll relocate the folder to the directory where deleted.
Now that you re-installed the platform tools, restart the Android Studio and your deployment targets should show up.
If you don't install the platform tool back and ever try to build or run a project you'll get this IDE error. Just FYI :)
So that's all. Enjoy.
Happy coding
If you use Windows, you might have a corruption in api-ms-win-crt-runtime-l1-1-0.dll.
Try to update it - you can get the update from Microsoft's website.
You should check it - path/to/sdk/platform-tools and try to run adb.exe
When you update Sdk platform tools(which contains adb.exe) to release 28.0.2 and if you are using windows 8.1 then it needs few updates from windows.
As per SDK Platform tools release notes(https://developer.android.com/studio/releases/platform-tools):
Updated Windows requirements : The platform tools now depend on the Windows Universal C Runtime, which is usually installed by default via Windows Update. If you see errors mentioning missing DLLs, you may need to manually fetch and install the runtime package."
Windows update url: https://support.microsoft.com/en-ca/help/2999226/update-for-universal-c-runtime-in-windows
Prerequisite for Windows update url: https://www.microsoft.com/en-us/download/details.aspx?id=42327
Faced the exact same issue but after updating with prerequisite url first then the other url provided now it is working perfectly fine for me.
It worked for me by selecting -> Use libusb backend
This worked for me on Windows:
Goto cmd write %temp% hit enter -> delete all data from there.
Restart your Computer.
Open Android Studio now, it will work.
Clear all cache memory (related to Android Studio)
Restart ADB manually from Android Studio (first option)
Open Command prompt and got android sdk>platform-tools> adb kill-server
press enter
and again adb start-server
press enter
Restart ADB manually form Android Stidio (second option)
go to your (SDK store path) sdk>platform-tools>adb
press enter
ex. D drive > sdk>platform-tools>adb
Restart your system
Delete the platform-tools folder from the sdk and replacing with the same from your another pc. I am also facing this problem after updating to 3.4. If you face same problem please update to Android Studio 3.5 Canary Channel.
The reason is for ADB server problem. Simply re-run your adb.
(Go to your SDK folder then inside platform-tools folder you can see adb.exe. copy the path location and paste it in your computers system Environment variable. Set a new path there and paste the adb.exe file location there. hope it will solve )
If you are using Genymotion, there is an update that fix the problem.
Genymotion 3.0.2 (April 18th, 2019)
Corrections
We have fixed an
incompatibility with the adb tool bundled in the platform-tools 28.0.2
package of the Android SDK, which caused failures to start virtual
devices.
This new version of adb changed the behavior of the “adb connect
:” command by making the “port” part mandatory. This
broke Genymotion Desktop in a few places where it did not pass the
port. We have adjusted the way we call “adb connect” and also updated
the version we ship with the product to match the one in
platform-tools 28.0.2.
If non of the above answers worked for you (as same happend to me), down grade to the old version of Android Studio by following these steps:
Uninstall current Android Studio
Go to Android Studio Archive and download any older version
After installation, Open the project. You might see an error like this
This version of Android Studio cannot open this project, please retry with Android Studio 3.4 or newer.
Now, open project gradle and update classpath tools.build version. I.e. in my case Android studio version is 3.2 and classpath 3.2.1
Hope it might save someone time.
I faced this issue last night, and I tried these methods to fix:
download older platform-tools and place it in the android sdk folder.(not work for me)
adb kill-server, adb start-server.(not work for me, adb had no response with these cmd)
kill the process that occupies port 5037.(for me, there is no other .exe run at this port)
reinstall platform-tools in Android Studio.(not work)
download ADB Kits and replace them in platform-tools folder.(work!!!)
It seems that my adb file has been modified or replaced by some programs. You can try these methods, and I hope some of them can work for you.
I had this issue only after a Genymotion update, on Mac.
What worked for me: Open Genymotion preferences, Select ADB, choose "Use custom Android SDK tools" and points to your Android SDK folder.
Actually the problem is not with the android studio version 3.4
Problem is with the android platform tools version which is latest one 29.
So install the previous version of the android platform tools version it will solve your problem. as above #Ved mentioned.
Ved link:
https://dl.google.com/android/repository/platform-tools_r26.0.0-windows.zip
EndTask adb.exe from Background processes (TaskManager) and Run Application again.
It works for me
I want to reset my PC,so all my installed softwares will vanish after resetting.I have the setup of older version of android studio but I updated it to newest version few days back.I can use the newest version of Android studio but I don't have its setup.How can I get the setup of newest version without needing to downloading anything so that I can use it after I reset my PC?
Do not worry, just copy your android-studio folder and Android Folder and copy it to a safe drive then reset your pc ...
So I got my new laptop(Win 10) and installed the Android studio 2.2.3 with SDK bundle.
When I first executed Android Studio it got stuck on the splash screen. adding "Add disable.android.first.run=true" to the idea.properties file solved it.
After I got to the first screen, I needed to configure SDK in order to create new project so I clicked on Configure->Project Defaults -> project structure.
I set the location of the SDK and JDK , and then it gets stuck with the "Checking Availability" message:
Checking Availability
I also tried to configure the sdk by clicking from the first screen on
Configure -> SDK Manager.
In this screen it also gets stuck with the message :Looking for updates":
Looking for updates
I tried to install it as Administrator and also to install lower version.
It didn't help.
Thanks in advance
First of all update Android Studio to latest version(V2.3.1) with complete bundle.
Then you don't need to install jdk manually. after finish installation check "Use embedded jdk" in project structure if not checked. and if you needed Android NDK kit then you can download it later.
Today I'm trying to update the SDK in Android Studio on my Ubuntu, and looking for the menu that make the download process running in the background. So I want to download the SDK and continue to work in Android Studio.
As far as I can remember Eclipse has menu that can download in the background task so I can continue work while downloading.
I've tried to find the option in settings but I could not find it, and on the downloading GUI has no option to download it in the background, here is my screenshot:
Is anyone having the same issue here? How can I resolve this?
You can go to tools -> android -> sdk manager and click on Launch stand alone sdk manager hyperlink. This will open sdk manager outside android studio, select the packages and download. You can continue to work on android studio this way.
The "Launch standalone SDK Manager" option seems to be gone in Android Studio 2.3.3 for Windows. However, there is sdkmanager.bat in \tools\bin
It is possible to do it all by code using the sdkmanager tool.
The sdkmanager is a command line tool that allows you to view,
install, update, and uninstall packages for the Android SDK.
This is an example using the sdkmanager with the command line:
First at all, the sdkmanager is located in android_sdk/tools/bin/.
Go where the sdkmanager is located
List installed and available packages using this command:
sdkmanager --list
The result willl be something similar to this
In my case I want to Download a System Image with Release Name "P" with ABI x86 ( I saw this information from Android Studio)
The next step is to search that system image in your list
Finally install this package in this way:
./sdkmanager "system-images;android-P;google_apis;x86"
This will begin the process of downloading the package
After finish you can check that the image is available to use

Upgrade to latest version of Android Studio (Currently in 2.3.1).
It now support download (both SDK and plugins) in background.
I have android studio version 0.4.2 and want to upgrade it to version 0.8.9. I am using ubuntu. In linux there is no installer for android studio. So, I downloaded the android studio version 0.8.9. Now should I just run the studio.sh file in the bin directory? Are there any precautions that I have to take? How do I make sure that this act as an update rather than just running a new android studio (what about my previous workspace, dependencies etc)?
Your version (Preview) uses ~/.AndroidStudioPreview to store the configs. Starting 0.8 the configs are saved in ~/.AndroidStudioBeta.
After first start, the new version will ask to import from old install. Point it to ~/.AndroidStudioPreview and you'll be good to go.
