Flutter: Android Platform Tools 29: Error retrieving device properties for ro.product.cpu.abi:

[vanlooverenkoen]

When I try to run my app in an emulator in Android Studio I get the following error. I have to say that it worked before and stopped working after some updates of SDK to v.29. Is there something I have to change now?

Reinstall of android studio and flutter did not work, I tried to kill and restart adb server and disabling heap protection. nothing worked

[brunocerk]

Exactly same error here, tried the same things

[vanlooverenkoen]

Did you update your platform tools to 29 as well?

[brunocerk]

I updated everything yesterday, there was 3 or 4 tools updates to do, i think platform tools was one of them.

[vanlooverenkoen]

I was working on a project in Android studio stable. But auto imports are only supported in the Android studio beta. I downloaded the Beta version on my windows. and boom everything was broken. The installation updated the platform sdk to 29

[brunocerk]

I'm setting up everything to work on Windows, installed Android Studio using JetBrains Toolbox, installed all de SDKs and tools, but when i tried to build on emulator it showed up the error, moved to real device, same thing, then i started looking for solutions

[SValab]

On stable i'm getting the same error after updating to 29. You can do a quick test to see the error using flutter doctor instead of running your project. Just make sure your device is running / connected.

[vanlooverenkoen]

I found a temporary fix while we wait for a solution provided by the Flutter team

Windows: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip
macOS: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-darwin.zip
Linux: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-linux.zip

this download contains the platform tools for 28.0.1

if you back up your platform-tools folder and place the content of the zip in the platform-tools folder.

this should be in your platform-tools folder

THIS IS A TEMPORARY FIX, NOT A SOLUTION

[brunocerk]

I prefer going back to my Linux boot where i haven't upgraded it, but thats a nice workaround, thanks for it!

[heinrichreimer]

@vanlooverenkoen You could also just download the platform-tools folder from official Google servers:

• Windows: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip
• macOS: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-darwin.zip
• Linux: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-linux.zip

[vanlooverenkoen]

Aaah nice. I couldn't find the links :D thanks. I updated my comment as well

[heinrichreimer]

@brunocerk Downgrading isn't hard.

1. Navigate to the Android SDK folder.
2. Remove platform-tools folder.
3. Unzip downloaded platform-tools from version 28.0.2, the last version before 29.0.0.

On Bash these are the commands you need (run at Android SDK home):

rm -r platform-tools
wget -O platform-tools.zip http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-linux.zip
unzip platform-tools.zip
rm platform-tools.zip

[Martin-P]

@vanlooverenkoen Thanks for this temporary fix.

For anyone who does not know where to find the platform-tools folder (at least I did not know :wink:), the folder screenshot in https://github.com/flutter/flutter/issues/33938#issuecomment-499250288 can be found at the following location:

C:\Users\[your-username]\AppData\Local\Android\Sdk

(AppData is a hidden folder by default)

[dxdiagmauric]

Same problem, fix platform-tools

[intercorps]

Its impressive how 2 google projects dont take care of this massive issues in consideration. This workaround works for now...

[kepuza]

same problem 5 hour ago

[mccreeper98]

@vanlooverenkoen Gracias por esta solución temporal.

Para cualquier persona que no sepa dónde encontrar la platform-toolscarpeta (al menos yo no sabía😉), la captura de pantalla de la carpeta en # 33938 (comentario) se puede encontrar en la siguiente ubicación:

C:\Users\[your-username]\AppData\Local\Android\Sdk

( AppDataEs una carpeta oculta por defecto)

other option windos + r, type %appdata%

[GuilhermeVendramini]

Same problem here.

[PhilParisot]

I have the same problem, I'm on the Android Studio stable channel and I rather wait for a fix instead of downgrading. How will we know if a fix is coming to the stable channel? How about the Beta/Dev/Canary Android Studio channels? Or will the fix have to be on the Flutter SDK side?

[shamoore]

Same issue. did the work around for now but that's inconvenient.

[470772345]

thanks~

[jp1017]

Download http://dl.google.com/android/repository/platform-tools_r28.0.3-windows.zip makes it.

Huge thanks!

[Cvilia]

saved me!

[jj007force]

Thank you! Downgrading the platform tools fixed the issue. Hope a newer sdk update or flutter update comes out to fix the issue with version 29.

[meidikawardana]

thank you.. I got problem yesterday and wake up till 3AM trying to solve this problem. now I am curious, how I can file an issue so this issue can be solved by Google's developers?

[Sun3]

Same error here too.

[MonipichMP]

same here

[PrimeFactor7]

Same issue with 29, downgrade to 28 workaround is functional

[vanlooverenkoen]

Please upvote the question so it had a high priority

[mohabmm]

same is here

[veluisg]

I'm starting with Flutter and just got this error. I downgraded to 28 and it worked!

[blacknepia]

saved me.

[akshay512]

Probably androidx app may work I guess..

[vanlooverenkoen]

Have you already tested it with AndroidX?

[akshay512]

Just my suggestion not yet tested check this out whether it works or not

Can you upload your "platform-files" folder to google drive or etc.?

[samuelg123]

@hybrayhem38
Try this (if you using windows).

1. Download http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip
2. Close Android Studio
3. Open command prompt & run this >> taskkill /f /im adb.exe
4. Move old platform-tools folder somewhere else (as a backup).
5. Extract platform-tools_r28.0.2-windows.zip to old path
6. Open Android Studio and it should work again

I don't know if I'm the only one, but I find myself spending an extraordinary amount of time getting Flutter and Android Studio emulator to work on a fairly regular basis. It's really killing the productivity promise of Flutter.

Have you already tested it with AndroidX?

AndroidX also got this problems

[Alfie-AD]

Very true. But i guess flutter is still fairly new and these bugs can be forgiven. Future still bright.

Try this (if you using windows).

1. Download http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip
2. Close Android Studio
3. Open command prompt & run this >> taskkill /f /im adb.exe
4. Move old platform-tools folder somewhere else (as a backup).
5. Extract platform-tools_r28.0.2-windows.zip to old path
6. Open Android Studio and it should work again

@vanlooverenkoen
Thank you for your fix. It works!

Work on me thx

Is this a permanent and actually solution?

[vanlooverenkoen]

@kavinraju the sollution is located in one of the first comments. And @aam has merged a pr

[PhilParisot]

Will the fix be pushed on the Stable branch?

[kavinraju]

Thanks a lot, the issue is fixed. :)

[vvinogradsky]

After the upgrade adb.exe would keep crashing non stop.
Downgrading platform tools to 28.0.2 saved me! What a scare!

[genX-flutter]

Thanks, was suffering from this since morning. finally resolved. Big thanks :)

[jotisa]

Hi! Did anyone try adb.exe v 28.0.3?

[bhurlbert]

I just ran into this. Thanks for the solutions above! Fortunately, I didn't have to spend much time on it thanks to the solutions and comments here in the last 24 hours.

One comment regarding emulator performance caught my eye, because i had some performance issues in the beginning too. I am using _Windows_ and I was developing with _Flutter_ on a beefy laptop, but it wasn't enough. I experienced difficulty keeping the emulators running, rebooting etc.

My unsolicited advice? Get a powerful workstation if you can and you will love developing in _Flutter_ again. This is what I replaced my laptop with a month ago and it changed my Flutter dev life immediately. :)

The fix for this landed on master branch of flutter only at this point, will take time to percolate through the (dev/beta/stable) channels per https://github.com/flutter/flutter/wiki/Release-process.
Your options as things stand right now are either to switch to master channel of flutter or go back to 28.0.2 of android platform tools as folks suggested above (https://github.com/flutter/flutter/issues/33938#issuecomment-499250288)

[shariful2011]

thanks @aam, after I changed my channel the issue solved. Now I have 1.7.3-pre31

[cgarrido8102]

Error I am getting when running flutter doctor

[langaro]

Just had the same problem. Downgrading to 28 fix it.

[garyng]

So, to sum up (https://github.com/flutter/flutter/issues/33938#issuecomment-499670279):

1. downgrade platform tools to v28 (https://github.com/flutter/flutter/issues/33938#issuecomment-499250288)
2. switch to master channel of flutter:

flutter channel master
flutter doctor

🎉

[vivek7374]

it works thanks to all.

[aam]

Here are some more details on the issue and the fix that landed:

Underlying problem is that in recently released platform-tools 29.0.0 adb.exe shell ..., that flutter uses on Windows, returns "heap corruption" -1073740940 (0xc0000374) exit code on every invocation.
Normally flutter expect 0 exit code indicating successful completion of the adb.exe shell command, so non-zero exit code stops flutter tools early on in application compilation/deployment process.

The fix https://github.com/flutter/flutter/pull/33951 makes flutter to ignore this error code as adb.exe seems to be doing all the right things(except of the setting exit code to 0).

[sarahpoehler4]

Switching to master did not work. Downgrade sdk did not work. Problems over problems.

[GustavoContreiras]

Switching to master did not work. Downgrade sdk did not work. Problems over problems.

Got this problem just now. Solved by downloading http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip and replacing

Make sure you restarted vscode / command prompt

[sarahpoehler4]

I tried to replace platform tools. Nothing changed. I am using Android Studio.

[francyfre]

i replace platform tools: 28.0.1, 28.0.2 and 28.0.3... try to restart ADB: adb kill-server and adb start-server

NOTHING IS CHANGE! flutter run dont GO for the first problem here up!!! flutter doctor tell me:
"Checking Android licenses is taking an unexpectedly long time...-Error retrieving device properties for ro.product.cpu.abi:"

NOW I finish all my idea!

thank
Francyfre

[GustavoContreiras]

@sarahpoehler4 try run through command prompt/terminal with flutter doctor -v and flutter run on your project folder. If that solves, try clean generated files/folder from your project with flutter clean or deleting .gradle folder

[Alfie-AD]

I tried to replace platform tools. Nothing changed. I am using Android Studio.

If this was the only error you a having then the solutions should fix it.
Are you still getting THE SAME error?
Did you close android studio before replacing the platform tools folder, or atleast restart after?
Running flutter clean in terminal helps.
Post your error report

[francyfre]

when i run project, from flutter run on CMD... system give me this error:Error retrieving device properties for ro.product.cpu.abi:

after finish with same error upstairs here!

[shariful2011]

I did git pull(if you are far behind from version), flutter channel master and flutter doctor, problem solved. Try these 3.

[francyfre]

probably yess... why is need to change branch?

[shariful2011]

because stable branch needs some times so that's why change to latest master.

[francyfre]

@shariful2011 you HAVE REASON... i solve my problem!!

repeat for all:
_cmd on Flutter folder
_git pull
_flutter channel master
_flucter doctor

and all problem is solved!! thankSoMuch @shariful2011

[sarahpoehler4]

after switching to flutter master I get this error:
bash: /c/Users/flutter/bin/flutter: No such file or directory

[AnthonyMansour]

https://github.com/flutter/flutter/issues/33938#issuecomment-499841930 worked for me. Thanks!

[kleinstein]

i had the same problem.
After i only changed the channel to master without downgrading platform tools to v28, it also works fine.
(the default channel was origin, i think...)

[sarahpoehler4]

after switching to master the flutter directory isnt ascertainable.

[axellebot]

I had an issues when I updated Android Studio but the work around https://github.com/flutter/flutter/issues/33938#issuecomment-499250288 worked for me

[kleinstein]

after switching to master the flutter directory isnt ascertainable.

-> well.. you can change it again from master to stable..

[sarahpoehler4]

no I can't. bash: /c/Users/flutter/bin/flutter: No such file or directory
After the webview issue now this issue...

[TikoZiko]

Thank you guys 👍 for saving me.
I was about to go crazy, tried everything from upgrading Platform to reinstalling Android Studio....

Now, I receive a msg that Android SDK Platform-tools are ready to be upgraded. :) Guess we should ignore this until further notice from the flutter team about the permanent fix.

[rubenmarcuspaschoarelli]

Its worked ! I am used platform-tools_r28.0.2-windows
Thanks!

[aaugmentum]

Thanks a lot)

[ahmetozde]

Downgrading to r28.0.2 fixed my problem. Thanks a lot..

[Delfin333]

i had the same problem.
After i only changed the channel to master without downgrading platform tools to v28, it also works fine.
(the default channel was origin, i think...)

Thanks.. It's works for me too..

[Hussain-AlBayyat]

It's works for me too. Thank you.

[bhavikvashi1804]

I found a temporary fix while we wait for a solution provided by the Flutter team

Windows: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip
macOS: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-darwin.zip
Linux: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-linux.zip

this download contains the platform tools for 28.0.1

if you back up your platform-tools folder and place the content of the zip in the platform-tools folder.

this should be in your platform-tools folder

THIS IS A TEMPORARY FIX, NOT A SOLUTION

this is not working

[Akash4097]

i just want to know that how may i suppose to notify whether i should update my android studio or not in future or i always stick to the same version even the updates are available.

[bhavikvashi1804]

@Akash4097
update android studio does not create the problem
but after updating android studio you need to manually downgrade platform tools and never update it until google fix it

[Akash4097]

hey @bhavikvashi1804 that means i need to do these solution manually until google fix it

[bhavikvashi1804]

@Akash4097
Yes but It works with latest version just changing platform tools downgrading

[Akash4097]

@bhavikvashi1804 ok thanks for the help

[aseemydv]

Its impressive how 2 google projects dont take care of this massive issues in consideration. This workaround works for now...

..and this when they are planning to support Fuchsia OS with Flutter

[walkerrabelo]

@shariful2011 you HAVE REASON... i solve my problem!!

repeat for all:
_cmd on Flutter folder
_git pull
_flutter channel master
_flucter doctor

and all problem is solved!! thankSoMuch @shariful2011

Yes ! Works for me !

[lewcianci]

EDIT: I wrote a detailed guide on how to fix this issue here: https://medium.com/@lewwybogus/fixing-that-adb-error-when-you-try-to-deploy-using-flutter-ab479937df02?source=friends_link&sk=538df558221cf53e152384ba0e008a19

Just to chime in briefly on this, I'm moving to Flutter from Xamarin Forms because of the sheer amount of builds breaking in XF and there not being any way to debug what broke and why. Having platforms straight up break flutter deployments is scary for me, and reminds me of the painful workflow I left when working with XF :(.

Downgrading platform tools seemed to help though.

[hamza-sabri]

how come am getting an error and the "flutter doctor" reports no issues found :

[hamza-sabri]

am still having the same problem I've tride all the solutions but nun of them worked for me what to do plz help?!

IT works!

[djensen47]

I originally posted this is not a great experience for new developers coming to Flutter for the first time. However, the team was quick to address it. However, that fix is not in the latest download on the main Flutter site.

After switching to flutter channel master now flutter doctor asks me to download Visual Studio (not VS Code, the other one)

 X Visual Studio not installed; this is necessary for Windows development.
      Download at https://visualstudio.microsoft.com/downloads/.

Is this a new requirement to run Flutter?

Update: I just ignored the message and it works fine.

---

BTW, Flutter is great, I'm excited to use it, and the Flutter team is doing great!

[lewcianci]

This shouldn't be closed. Not fixed in stable.

[bharath79]

did anyone find the solution for this?

[NurGuz23]

If I downgraded to 28.0.2, when use --device, not recognize

[geekydiamond]

This is probably impacting every flutter developer on Windows yet still no fix on stable. Please could we either have stable fixed or an explaination why this shouldn’t be an emergency fix?

This gives a terrible impression of the stability of flutter and could impact developer adoption of it.

[wadeziegler]

The platform-tools_r28.0.2 fix worked for me too, but there really should be an emergency fix for this. Flutter stability has been an ongoing issue for me. Code keeps breaking with updates even after the beta period was finished.

[ZolderonGitHub]

that's dasen't work

[brecarv]

I did git pull(if you are far behind from version), flutter channel master and flutter doctor, problem solved. Try these 3.

Thanks bro, it works fine.

[16273849]

Thanks, Guys. You are Awesome.
This problem ties me up for two weeks.

[jonahwilliams]

Please see https://twitter.com/FlutterDev/status/1137033935089807365

[ilvassa]

Tanks for the work around!!!! ...
https://github.com/flutter/flutter/issues/33938#issuecomment-499250288

It was affecting both Windows and Linux enviroments for days... But it's bugging me that I've tried downgrading flutter and android sdk but for some reason it didn't work.... and now yes....

Now I'll wait for the real fix.

[fredgrott]

for easy way someone is keeping track and storing things on github https://github.com/awake558/adb-win

so makes it easy for manually installing and fixing

[iozuniga]

repeat for all:
_cmd on Flutter folder
_git pull
_flutter channel master
_flucter doctor

It worked for me too! BTW, I also runned 'flutter upgrade' after 'flutter doctor'.
I look forward to switch back again to the stable channel

[KaranSingh1412]

https://github.com/flutter/flutter/issues/33938#issuecomment-499854134
This steps seem to work very good,
Just launch to your flutter where you have installed it and write these commands to make it work;
git pull
flutter channel master
flutter doctor

just to repeat again

[mtb550-KSA]

I spent two days in my work to solve this issue... My Guaaaaaaaaaaaaaaaaaaaaaaaaaaaaad.
thanks brothers

[abc123james]

After update the platform tools , the problem solved

[GaboCuba]

I had the same problem. I uninstalled Platform Tools 29 on Android Studio and voilá!!! All working again! Thanks for the post.

[akshay512]

This is fixed now as we got a new update for platform tools 29.0.0 to 29.0.1

Confirmed. After the update to 29.0.1 y moved to stable channel and everything working.

打开Android Studio 根据提示把platform tools 29.0.0升级到29.0.1 就正常啦。

@vanlooverenkoen You could also just download the platform-tools folder from official Google servers:

• Windows: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip
• macOS: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-darwin.zip
• Linux: http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-linux.zip

This works!!!!!!!!!!!!!! Thnaks

For those still having this problem, try USB for file transfer instead of USB for charging or anything else. That did the trick for me.
