This might related to this issue #16025

HerbertKoelman · 2018-04-06T15:36:34Z

This issue is indeed related to the JDK's version. I was using a JDK v9 which apparently doesn't go well with Android Studio.

I've switch my JAVA_HOME env variable to a 1.8 version and flutter doesn't complain anymore:

$ export JAVA_HOME=`/usr/libexec/java_home -v 1.8*`
$ flutter doctor --android-licenses
...
$ flutter doctor

Go to SDK root

open a Terminal on this folder, and run the command:
sdkmanager --licenses

thanks!

@saurabh47 If the suggestions don't work for you please create a new issue with full information (flutter doctor output). Comments on closed issues are easily overlooked.

rushikeshmore · 2018-09-05T15:27:21Z

To solve that problem Run following command:

flutter doctor --android-licenses

I guess solve your problem Happy to enjoy Flutter

lakshyapunhani · 2018-09-10T18:42:25Z

Following command flutter doctor --android-licenses gives command not found

rushikeshmore · 2018-09-11T01:54:58Z

@lakshyapunhani Run CMD in administration thenrun following command -

                   flutter doctor --android-licenses

I hope your problem is solved

git bash to flutter/bin directory and run flutter doctor --android-licenses.
This worked for me.

zoechi · 2018-10-31T06:56:16Z

@stickyboiproject did you check if the directory is correct?
That's not really a Flutter issue. You need to install and set up Java properly.

paulolimarb · 2018-11-29T21:02:35Z

I resolved this problem setting this environment variable.

export JAVA_HOME="/usr/lib/jvm/default-java"

I worked around the issue and finally figured out the solution. I got two errors which were

Android toolchain - develop for Android devices (Android SDK 28.0.3)
✗ Android license status unknown.
Android Studio (not installed)

so I am working on android studio and Flutter from my External Hard disk and as the android studio was installed but the command Flutter Doctor did not find it as it was not installed under Applications .

I had to fix Android studio(not installed) first. So my work around was flutter config --android-studio-dir="YOUR ANDROID STUDIO DIR". This solved the installation error.

The toolchain error was simply solved after making sure that the android studio was installed and using the command flutter doctor --android-licenses

alfeyo · 2019-01-14T13:13:26Z

I had the same problem on Linux. In my case it was the way I installed android studio, from a zip file and not from the software centre, try deleting android studio and reinstalling it from the app store. and now try flutter doctor --android-licenses hope this helps

zoechi · 2019-02-19T17:42:04Z

@OsamaxD1 better to ask on StackOverflow. Seems your PATH environment is not set up correctly.

harimau99 · 2019-02-25T00:07:40Z

Hi. I have question. is it possible no to have install android studio version sdk, instead using cli version of sdk.
is it possible?

zoechi · 2019-02-25T06:04:40Z

@harimau99 yes, it's possible

mitulp534 · 2019-03-16T08:06:30Z

flutter doctor --android-licenses
this is the best solution for this issue

exactly

Bohne13 · 2019-04-25T19:36:19Z

It looks like flutter don't like the openjdk--11 version of java, since Ubuntu 19.04 the version 11 is the default version.

zhaozhao · 2019-05-15T01:40:40Z

flutter doctor --android-licenses will not respect your http_proxy env variable.
you can manually update android licenses by
~/Library/Android/sdk/tools/bin/sdkmanager --proxy=http --proxy_host='web-proxy.xxxxx.com' --proxy_port=8080 --licenses

shahprashant030 · 2019-07-05T04:43:37Z

I got this error when I entered flutter doctor:

[!] Android toolchain - develop for Android devices (Android SDK version 28.0.3) ! Some Android licenses not accepted. To resolve this, run: flutter doctor --android-licenses

Then I tried running flutter doctor --android-licenses and I accepted every license by entering Y and it solved my problem.

If you are working on windows then first try executing it in cmd. But if it doesn't work then try executing it through Windows Powershell.

anderzilla · 2019-07-16T23:42:05Z

Thanks @Snapjv
your coment save me! lol

moshTech · 2019-08-23T04:29:05Z

All you need to know is that you have to downgrade to java-8 then try this after installing java-8 and make it default
on linux: try this on your terminal
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/
then
flutter doctor --android-licenses
and continue with the responses you get.

ar4hc · 2019-09-20T09:45:08Z

for me on mac the issue seemd to be the JAVA_HOME variable.
i have jdk13 and openjdk 8 installed.
Even with jenv setting pointing to 1.8, but JAVA_HOME didnt exist,
flutter or androidsdk seemd to pick up jdk13 and fail with a red hering saying an update for androidsdk is avaialble
Each of flutter and adroidsdk worked separetly.

Setting java_home env to the 1.8 directory helped and flutter or androidsdk picked up the correct java stuff and it worked.

Looks to me like flutter and androidsdk had problems finding the correct java without the explicit JAVA_HOME.

ajeethhacki · 2019-09-22T06:09:21Z

@lakshyapunhani Run CMD in administration thenrun following command -
                   flutter doctor --android-licenses

cseas · 2019-09-22T12:32:07Z

The answer here helped me solve the issue on Ubuntu 18.04 with Java 9.

As mentioned in the above link, you just need add the following line to your bashrc file:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

Save the file then run:

source ~/.bashrc
flutter doctor --android-licenses

The terminal will ask you to review the licenses. Accept them by the entering Yes and the issue should be solved.

FlashJonas · 2019-09-25T12:53:18Z

I got rid of the error by using the solution described here #39549 by @lookfirst
JAVA_OPTS="" JAVA_HOME="/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home" flutter doctor

Larpoux · 2019-10-28T03:41:49Z

Thank you @FlashJonas .
Changing $JAVA_HOME to point to "/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home" solved my problem.

Burak-Ibrahim-Unal · 2019-11-19T09:44:35Z

Go to SDK root
C:\Users\%user%\AppData\Local\Android\Sdk\tools\bin
open a Terminal on this folder, and run the command:
sdkmanager --licenses

thanks!

Thanks.It fixed my problem.

magician20 · 2019-12-22T16:41:21Z

I had the same problem.
I used this way:

Go to SDK root
C:\Users\%user%\AppData\Local\Android\Sdk\tools\bin
open a Terminal on this folder, and run the command:
sdkmanager --licenses

Didn't work ,so i remove all java path from environment variables then used the above way again and worked.

Ahabdelhak · 2020-01-01T20:10:41Z

try running flutter doctor --android-licenses and accepting every license by entering Y .
This solution solving my problem.

gr3grisch · 2020-01-03T18:40:14Z

I tried the Flutter SDK one year ago and I had an issue regarding Java 8 (I was using java 11)
and after one year I still need to change the bat file to edit the JAVA PATH to version 8. Exactly the same issue than one year ago: (at least it will be quicker to fix)

:findJavaFromJavaHome
set JAVA_HOME=%JAVA_HOME:"=%
set JAVA_EXE=%JAVA_HOME%/bin/java.exe

if exist "%JAVA_EXE%" goto init

--->

@Rem Execute sdkmanager
"%JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% %SDKMANAGER_OPTS% -classpath "%CLASSPATH%" com.android.sdklib.tool.sdkmanager.SdkManagerCli %CMD_LINE_ARGS%

It raises an exception (cause of java 13)

Do you think youo will be able to synchronize with the folks who work on Android SDk?

Thx
Best rgds

agusarifbimawan · 2020-02-02T04:26:58Z

Downgrade java version to jdk1.8.0_241 and update your java path

@rubankrish Looking at your screenshot, the issue is resolved. It's saying: All Android licenses accepted which is what is expected.

rubankrish · 2020-03-13T07:34:01Z

@vickz84259 Everything looks okay but what about this warning

Android NDK location not configured (optional; useful for native profiling support)

It is okay or I need to setup anything, Please guide me.

ifanchu · 2020-03-28T17:33:56Z

Well, in my case, apparently I didn't give consent to those Android licenses.

When I ran

~/Library/Android/sdk/tools/bin/sdkmanager --licenses

It popped up a few software licenses and I had to choose 'y' for each of them then the issue is fixed.

lookfirst · 2020-03-28T18:12:59Z

houssem-mallat · 2020-04-03T15:28:24Z

Hello Everyone , all you need is here 👍

1 - remove java JDK
In your macOS terminal type this one by one

sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo rm -fr /Library/PreferencePanes/JavaControlPanel.prefPane
sudo rm -fr ~/Library/Application\ Support/Oracle/Java

After that you can navigate to specific version of java that you intend to delete by using the following command:

cd /Library/Java/JavaVirtualMachines

check java version that you have

java --version

sudo rm -rf jdk-13.0.1.jdk

Instead of jdk-13.0.1.jdk you can give any version number in your system.

2 - reinstall Android SDK Tools (Obsolete) in Android Studio
3 - Restart your IDE
4 - Problem resolved
