I am using Windows 10 and when I launch the Virtual Device Emulator in Android Studio I keep getting the message which reads:
"The ADB binary at C:\Users\siviw\AppData\Local\Android\Sdk\platform-tools\adb.exe is obsolete and has serious performance problems with the Android Emulator. Please update to a newer version to get significantly faster app / file transfer".
I am a new developer with little experience. What do I need to update to a newer version so that message is no longer shown?
I am new to android as well. dkalev's answer is correct but not very descriptive for a new user. I have outlined the steps below.
Double Shift to open the search box
Type SDK Manager
In the results shown click "SDK Manager"
In the window that opens click the second tab "SDK Tools". You should see that there is an update available for SDK Build-Tools on the first line
Check "Show Package Details" in the lower right hand corner
Scroll to the last (latest version) item under "SDK Build-Tools" and check the box. (Mine was 28.0.1)
Click "Apply"
In the dialogue box that pops up, click "OK"
When the installer finishes, click "Finish"
Uncheck "Show Package Details" and look at "Android SDK Build-Tools" (first line). There should be no update available and it should say "Installed"
Click "OK" to close the SDK Manager
For me, update SDK doesn't help. I solve this problem by unchecking the emulator option "Use detected ADB location". Give it a try.
I had the same problem and solved it by updating the Android SDK Build-Tools. Open the SDK manager in Android studio (double shift and type SDK manager). Then on the second tab (SDK Tools) update the Android SDK Build-Tools and the error message should go away.
This is an years old bug.
Check your adb version like this : (the adb path is given with the error itself)
C:\Users\<your_user_name_>\AppData\Local\Android\Sdk\platform-tools\adb.exe --version
output :
Android Debug Bridge version 1.0.41
Version 29.0.4-5871666
Installed as C:\Users\sunil\AppData\Local\Android\Sdk\platform-tools\adb.exe
It means this adb comes from the latest sdk platform tools 29.0.4.
Check the latest version from official site here.
If you already have the latest version of ADB installed, and still getting the error, this is a known issue. Google hasn't yet provided any other ADB. Click on the "never show again" option and continue.

This works for me.
Just opened Android SDK Manager Then it showed 4 Updates Available. So I just Updated it and No more above warning.
Had the same issue but in my case the fix was slightly different, as no updates were showing for the Android SDK Tools. I opened the Virtual Device Manager and realised my emulator was running API 27. Checked back in the SDK Manager and I didn't have API 27 SDK Tools installed at all. Installing v 27 resolved the issue for me.
In my case what removed this message was (After updating everything) deleting the emulator and creating a new one.
Manually updating the adb didn't solved this for. Nor updating via the Android studio Gui.
In my case it seems that since the emulator was created with "old" components it keep showing the message. I had three emulators, just deleted them all and created a new one. For my surprise when it started the message was no more.
Cannot tell if performance is better or not. The message just didn't came up. Also I have everything updated to the latest (emulators and sdk).
This happened to me. And, in my case I need Android SDK Platform 29 because I am using react native 0.63 and Android 10 (Q). I had to uninstall Android SDK Platform 28 because it was the one that caused the warning.
I found this video See Here explaining the process.
Open Android Studio then click on configure
Go to SDK Manager
Go to SDK Tools and click show package details
Uncheck Android SDK Platform 28 (OBS: for me) and Apply
Click OK and Finish.
With this I was able eliminate the warning.
I had the same problem and solved it by updating the Android SDK Build-Tools in Android Studio.
step 1 - Double shift and type SDK manager, this will open the SDK manager
step 2 - Then on the second tab (SDK Tools), update the Android SDK Build-Tools and the error message should go away.
if this does not resolve check the option in Setting tab,use detected Adb tool in Setting tab
(You mentioned you are new to Android Studio) so I recommend pressing the Android Studio > Help > Check for updates... button that will update your environment.
I solved this error by uninstalling two older SDK build tools versions, leaving only the most recent one.
The solution that worked for me -
I closed my Android Studio.
I visited this site - https://androidstudio.io/downloads/tools/download-the-latest-version-of-adb.exe.html
From there I downloaded the latest adb.zip file
I unzipped the folder and copied the 3 files -
adb.exe
AdbWinApi.dll
AdbWinUsbApi.dll
I went to the folder - C:\Users\PayelSenapati\AppData\Local\Android\Sdk\platform-tools
There I replaced the old files by the new files. (Paste followed by replace the existing files)
Then I reopened my Android Studio, opened my virtual android device. Everything went fine. The error was no more.
In the SDK Manager, in the SDK Tools tab, check if you have any updates, if not, deselect "Hide Obsolete Packages" and check if you have something marked as (obsolete) if so, deselect the item and apply. In my case, it was the Android SDK Tools.
First you need to check which SDK your Emulator is using and as #kuya suggested you need to follow those steps and install the latest version of that SDK Build Tool. Suppose your Emulator uses SDK 27 then you need to install latest in that series. For me it was 27.0.3. After that the error was gone.
Try factory reset to virtual device from Android Device Manager
None of the top-voted answers worked for me, except when I unchecked "Use detected ADB location" as mentioned above by #褚阳光. Fortunately, in my case though, the message didn't show up, even when I turned it back on. In other words, the problem might be resolved by restarting "Use detected ADB location" :)
Try update your SDK Tools items, and then delete all currently created emulator and recreate again. it works for me
This might sound normal but I was getting the same error but just updated it and it worked now without any error. I suggests anyone to try for updates first.
If you are stuck after following each of the steps outlined in above, I will suggest you combine more than one answers. The answers of #Kuya and #褚阳光 worked for me. Try them out. I can explain more if the steps are yielding results for you.
This can also be an issue with hyper-v settings on Windows 10 pro. Because with this error I was facing BSOD - https://www.techclassy.com/fix-hypervisor-error-bsod/
I faced the same issue, and I tried following things, which didn't work:
Deleting the existing AVD and creating a new one.
Uninstall latest-existing and older versions (if you have) of SDK-Tools and SDK-Build-Tools and installing new ones.
What worked for me was uninstalling and re-installing latest PLATFORM-TOOLS, where adb actually resides.
I got this error and I tried all the possible solutions that I found on every site, nothing worked.
I was working with flutter, and the command flutter doctor showed me that I need to accept a few agreements
I did that and ADB started to work
So conclusion:
If nothing works, install flutter, run flutter doctor, execute the commands that flutter doctor suggests to you. This should solve your problem
the command was: flutter doctor --android-licenses
I followed the answer, but the magic final step was deleting the existing virtual environment and creating a new one.
Whenever I check for update, I keep getting this error
And I have no problem with my connection.
I would suggest updating manually by downloading and installing the latest version from the Android Studio homepage. Depending on the "jump" in versions (e.g. from 1.9 to 2.1), this will either update the currently installed version or install the new version alongside it, letting you import your settings from the old version. The updated version should then be able to check for updates correctly.
Otherwise: Try deleting the Android Studio settings folder in your Windows user directory. Are you behind a proxy? Make sure your PC's date/time settings are correct.
I am getting this in my Log cat Window from last week. What if I will update? I am little nervous if new version will be different from which i m using Android 1.5.1
After pressing "Available" in Log Cat I get
What to do now.?
Change is always good in the long run.
If the new version is a stable version,you should switch.You can check latest stable build here.
You can see this video to run 2 different versions parallely if you want to have a preview
You can see release notes to see what has been updated .
Android Studio 2.0 has instant run for builds which will save you a lot of time.
Update wouldn't change IDE drastically. You will only get newly features which are added in every updated addition.
like Android Studio v2.0.0 has Instant Run feature
Android Studio now deploys clean builds faster than ever before.
Additionally, pushing incremental code changes to the emulator or a
physical device is now almost instantaneous. Review your updates
without redeploying a new debug build or, in many cases, without
restarting the app.
Read Android Studio Release Notes.
My current Android Studio installation (linux-64bit) is showing a pop-up saying there is a new Version of Android Studio 2.
I am unable to download the current stable of Android Studio.
The download-link (on big green button) reffers to the Terms and Conditions. If i Accept and klick the button (which is showing no text, which is also strange) it redirects me to the index page again.
Here is the index page: http://developer.android.com/sdk/index.html
Have they withdrawn the release or something? Does anybody know a direct-link?
Thank you for any help on it
You need to have a little patience and try to check for update from time to time until you'll be able to update Android Studio from within the IDE. I encountered the same issues as you but after a while it worked well.
My advise is to wait with the upgrading to 2.0 and stick with your 1.5 version because a lot of people here have problems with Android Studio 2.0 (for now it is kind of buggy, maybe later Google will fixed some issues...).
As an example of my problems with Android Studio 2.0 I've posted recently, check this: After upgrading to Android Studio 2.0, I cannot change the screen orientation in the Android emulator, but of course it is your decision to upgrade or not :) .
P.S. I'm a linux user too.
As this is entirely a new version, you will not be able to update (or upgrade) from within the app.
You will have to download the installer and install at the same location replacing your Android studio 1.5
I did the same thing and is working for me.

Has anyone been able to upgrade from within the Android Studio Preview (canary channel) to Android Studio beta or do you have to start with a fresh beta install?
You cannot upgrade Android Studio Preview to Beta. These are two different products. You have to uninstall the preview and install the beta. It was straitforward for me. Beta setup can even import Preview settings. I just had to update my build.gradle file (on a small project) since I also downloaded API 20. It was not more painfull than an ordinary canary update of Android Studio Preview after all ;)
This page may be usefull for a step by step Android Studio Beta installation guide: http://bugapart.blogspot.fr/2014/06/install-android-studio-beta-for-dummies.html
As Dazzibao said, you cannot. However I would like to point out that I can't seem to find the Preview version being advertized for download anywhere on Google's site anymore. It would seem to me then that it IS recommended to upgrade to Beta as soon as possible if you're already on the Preview build. I would have posted a comment to reply directly to amchang87's comment on going against recommending it, but I simply don't have the rep yet.
I'm swapping mine out as I type this.
