Automatically accept all SDK licences

Question

Since gradle android plugins 2.2-alpha4:

Gradle will attempt to download missing SDK packages that a project depends on

Which is amazingly cool and was know to be a JakeWharton project.

But, to download the SDK library you need to: accept the license agreements or gradle tells you:

You have not accepted the license agreements of the following SDK components: [Android SDK Build-Tools 24, Android SDK Platform 24]. Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager. Alternatively, to learn how to transfer the license agreements from one workstation to another, go to http://d.android.com/r/studio-ui/export-licenses.html

And this is a problem because I would love to install all sdk dependencies while doing a gradle build.

I am looking for a solution to automatically accept all licenses. Maybe a gradle script ? Do you have any ideas ?

Retrochoir

You can also pop an echo y | in front of that command to auto accept the licence. Useful when running on a headless CI box :) – Schulman

I had to do ~/.android/tools/android update sdk --no-ui --filter build-tools-25.0.0,android-25,extra-android-m2repository because the android tool was localized to my home – Symphonious

sdkmanager --licenses no longer works. I used --upgrade, ignored the errors and this sorted the license problems. – Ody

sdkmanager --licenses in Android\tools\bin folder worked for me! – Robin

I've used this command for CI environment build script with small adjustment. I've added --sdk_root=$ANDROID_SDK_PATH. Problem was that licenses were accepted and not saved to Android SDK root folder. Final command: yes | sdkmanager --licenses --sdk_root=$ANDROID_SDK_PATH (without sudo) – Euphemie

Be sure to have set $ANDROID_SDK_PATH to the actual root path where you've installed the SDK (i.e.: /opt/android-sdk), or just put the path directly (i.e.: yes | sdkmanager --licenses --sdk_root=/opt/android-sdk) – Boots

yes | sudo sdkmanager --licenses this throws an Error: Unknown argument --licenses @Retrochoir – Constantino

In ubuntu docker, this worked for me: RUN sh -c ' printf "y\ny\ny\ny\ny\ny\ny\ny\ny\ny\n" | ./sdkmanager --licenses – Upon

@Boots that comment is quite important actually, if you work through cmd it's very likely you set ANDROID_HOME, so it doesn't work whatever else you do – Merovingian

I haven't seen "sdkmanager --licenses" work on any SDK since ~2017 - FYI Use "sdkmanager --update" instead – Tulatulip

I get ye sno se reconoce como comando interno – Moskowitz

Where do you run yes | sdkmanager --licenses --sdk_root=$ANDROID_SDK_PATH because yes is not a command. – Moskowitz

for window open cmd and change dir to C:\Users\username\AppData\Local\Android\Sdk\tools\bin and execute " sdkmanager --licenses" – Anthropogeography

errors when executing sdkmanager --licenses with Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema at com.android.repository.api.SchemaModule$SchemaModuleVersion.<init>(SchemaModule.java:156) – Blasted

Note for Linux users, in my case there was a permission issue, so I used sudo, only to realize that after accepting the licenses, they still showed as not accepted under user. To solve this, precede the sdkmanager --licenses with sudo chmod a+w $ANDROID_HOME/licenses – Cephalometer

Answer 1

UPDATE 2021 This should be the accepted answer as its easy and upto date

---

AndroidSDK can finally accept licenses.

Go to Android\sdk\tools\bin

yes | sdkmanager --licenses

EDIT:

as pointed out in the comments by @MoOx, on macOS, you can do

yes | sudo ~/Library/Android/sdk/tools/bin/sdkmanager --licenses

as pointed out in the comments by @pho, @mikebridge and @ Noitidart on Windows, you can do

cmd.exe /C"%ANDROID_HOME%\tools\bin\sdkmanager.bat --licenses"

be sure to install java before

Retrochoir

On Widows I had to go to Run then C:\Users\x1\AppData\Local\Android\sdk\tools\android then it popped open a GUI and then install missing then click "Accept Liscenses" in new dialog that pops. – Decortication

This is not working for linux. There is no sdkmanager file under the tools/bin dir or somewhere else. Can you please help? – Tacet

On macOS, you can do yes | sudo ~/Library/Android/sdk/tools/bin/sdkmanager --licenses – Looney

How can I accept licenses automatically from gradle wrapper? – Schuss

On mac via CLI on the path /Library/Android/sdk/tools/bin, execute: yes | ./sdkmanager --licenses – Curtal

If automating this process (maybe using Travis?), you need to update sdkmanager first by running: sdkmanager --update – Mollymollycoddle

Finally, as of which version was this feature introduced? – Janot

This worked great in my Dockerfile where I had to accept all licenses during installation of certain packages in SDK manager: RUN yes | sdkmanager "build-tools;28.0.2" "platform-tools" – Neutralism

upvote to @Decortication for the path, but it didn't work, I had to run C:\Users\x1\AppData\Local\Android\sdk\tools\bin\sdkmanager --licenses from the command prompt and hit "y" + Enter to the prompts – Metalinguistic

Thanks @gangt for upvote and sharing the better path! – Decortication

Where do I find sdkmanager? It's not in my bin folder for the "Android Studio and SDK tools" that I downloaded. – Intelligentsia

Mine is at C:\Users\UserName\sdk-tools-windows-4333796 \tools\bin\sdkmanager.bat. – Incredulity

I have to change the location to { yes | sudo /opt/android/tools/bin/sdkmanager --licenses } – Antiphon

on windows, if you happen to have GitBash installed. you can run yes | C:\Users\x1\AppData\Local\Android\sdk\tools\bin\sdkmanager.bat --licenses there – Freeswimming

I had issues with this and couldn't run the sdkmanager, if you have an issue with it complaining about some Java.xml file, be sure you're using Java8 as I had Java11 set as my global version – Piccoloist

None of the command line stuff worked for me on Windows, but going to Tools -> SDK and downloading another SDK prompts you to accept licenses. – Filum

Good god android development is garbage. I started out a couple of years ago using one of their template examples, and every time I go back to it, there's a new version of android studio, and it takes hours to get that project - which was working fine - working again... – Camelopardus

"sdkmanager --licenses" hasn't worked in years and people still post it as a solution and people still upvote it. What am I missing? Y'all using old AF AndroidSDKs? – Tulatulip

One license was nicely accepted by command echo y| "%ANDROID_SDK_PATH%\tools\bin\sdkmanager" "ndk-bundle" on Windows. It must be without space between y and | – Ivoryivorywhite

On Mac while running the above command if you face issue like "zsh command not found sdkmanager Mac" it means you have not installed JDK. So please first install JDK and then run the above command. All licences will be accepted. Now you can proceed with your work like again run the project and you won't get any issue. – Scopula

--licences is not part of the SDK any longer! – Curran

I needed to follow this link before: #53995424 – Addieaddiego

I needed to add sudo prefix, then it worked. Otherwise it said "licenses accepted" but when I checked again they were not actually accepted. With sudo it became permanent. – Advantage

This actually doesn't work, because you're not downloading sdk's, so you still get halted. – Skiver

Lubuntu : I had to apt install sdkmanager and then type "sudo sdkmanager --licenses" TWICE (saying "y" the first time). – Actuality

Have a look at this page : #55829425 – Actuality

Answer 2

I was getting this error:

License for package Android SDK Build-Tools 30.0.2 not accepted.

So, I went to Tools -> SDK Manager -> SDK Tools. Then I installed Google Play Licensing Library. It solved the problem.

Smaragdine

I'm afraid I'm going to have to disagree with @AminPinjari and Cedric, this didn't make a darn bit of difference for me. – Verner

You dont have to reinstall everything - it is sufficient to run android-sdk/tools/bin/sdkmanager --licenses – Heterogenesis

Thank you, it is working on Windows with Android Studio Arctic Fox 2020.3.1 on 2021-08-02 – Jota

I don't understand why this is needed with a fresh install of AS but I'm happy that this answer exists! I just installed this and then did a gradle sync and all was great. – Cohen

I found and used this solution for my issues while I was using a Windows PC. I shifted to Mac, found the same problem and the same solution fixed my issue yet again. This is the best answer as of 2021. – Hydrops

This worked easily. But all the same building software is getting complicated. – Ace

It's nice that it works, but why???? why does it work? why is it needed? – Taper

And what is the equivalent on the command line? – Peirsen

can someone point out how can we do it using command line (debian)? – Diorite

Answer 3

I have encountered this with the alpha5 preview.

Jake Wharton pointed out to me that you can currently use

mkdir -p "$ANDROID_SDK/licenses"
echo -e "\n8933bad161af4178b1185d1a37fbf41ea5269c55" > "$ANDROID_SDK/licenses/android-sdk-license"
echo -e "\n84831b9409646a918e30573bab4c9c91346d8abd" > "$ANDROID_SDK/licenses/android-sdk-preview-license"

to recreate the current $ANDROID_HOME/license folder on you machine. This would have the same result as the process outlined in the link of the error msg (http://tools.android.com/tech-docs/new-build-system/license).

The hashes are sha1s of the licence text, which I imagine will be periodically updated, so this code will only work for so long :)

And install it manually, but it is the gradle's new feature purpose to do it.

I was surprised at first that this didnt work out of the box, even when I had accepted the licenses for the named components via the android tool, but it was pointed out to me its the SDK manager inside AS that creates the /licenses folder.

I guess that official tools would not want to skip this step for legal reasons.

Rereading the release notes it states

SDK auto-download: Gradle will attempt to download missing SDK packages that a project depends on.

Which does not mean it will work if you have not installed the android tools yet and have already accepted the latest license(s).

EDIT: Saying that, it still does not work on my test gubuntu box until I link the SDK up to AS. CI works fine though - not sure what the difference is...

Schulman

There is a small glitch in sdkDownload feature regarding some of the components, e.g., support-v4. It will update the components but gradle won't see update until next invocation. One workaround to exec gradle twice, once to throw away: gradle dependencies || true -- code.google.com/p/android/issues/detail?id=212309 – Sandeesandeep

you can use mkdir -p instead of || true. – Currish

It works thank you for this glitch, good to know. To check if your SDK path is defined as expected : echo $ANDROID_SDK – Wren

In my environment ANDROID_SDK is not defined, but it works with ANDROID_HOME – Whitman

This fails for Android SDk 26. – Lepage

Looks like another UID is needed for platform and build-tools: d56f5187479451eabf01fb78af6dfcb131a6481e. 8933bad161af4178b1185d1a37fbf41ea5269c55 still works for Google Repository and Android Support Repository. – Boggers

@Paul, Can you please add a code snippet which adds the new key. For me, the build is failing at the line "Downloading services.gradle.org/distributions/gradle-2.14.1-all.zip" – Enterogastrone

@stack_ved: I've just added another echo: echo -e "\nd56f5187479451eabf01fb78af6dfcb131a6481e" >> "${ANDROID_HOME}/licenses/android-sdk-license". But I think your problem hides somewhere else. – Boggers

true, the problem is with the new way of installing dependencies may be. SOmehtin like the accepted answer. Or what @Retrochoir has mentioned above. Any idea? – Enterogastrone

Turned out for me what @Boggers is suggesting worked. But i am looking forward to fix it for good. Thanks Paul! – Enterogastrone

any option to prevent gradle android plugin from automatic download of missing components? – Igbo

if you want to get this sha n8933bad161af4178b1185d1a37fbf41ea5269c55 you should run in your terminal sdkmanager --licenses at the bin folder of the path of your sdk , then accept it , then open the license file you accepted – Fcc

Answer 4

For the newest Android Studio (2.3) the best way to update/accept all licenses is to run:

cd $ANDROID_HOME
tools/bin/sdkmanager --licenses

you might still need to copy the licence files to other locations based on your setup.

Dioptrics

This looks like the best way to go and it works on all platforms too, just run tools/bin/sdkmanager --licenses – Deadlight

If you got old sdk manager --licenses wont work. It is necessary to copy tools folder to another location then use --sdk_root= and point it to your sdk folder, then you would be able to update tools to newer version. – Wells

can we pipe yes into this command somehow for automated build systems? You won't always have interactive console access to these machines, so pressing y on keyboard physically won't work. – Neutralism

Can anyone please guide me how to implement this solution? Got to add this line in build.sh? – Enterogastrone

it worked for me but i had to do cd $ANDROID_HOME before executing this command – Ogrady

Worked for me, but maybe you should add cd $ANDROID_HOME just to be more clear where to execute this, anyways thanks a lot. – Cotterell

I have android studion 3.0.1 I have updated all the sdk tools but I still see license error, I do try to run the command but I got this error: -bash: tools/bin/sdkmanager: No such file or directory – Polymerism

Not a valid answer to the question. This still needs manual input and thus it is not automatic as asked. – Chemotropism

Answer 5

For the new sdkmanager utility:

yes | $ANDROID_HOME/tools/bin/sdkmanager "build-tools;24.0.3"

There's a bit of a delay between yesses, so the command could hang with the license showing for a while, but it doesn't require human intervention.

Scraper

In my install debian9 I only have a sdkmanager.jar: android-sdk-linux/tools/lib/sdkmanager.jar and # java -jar /android-sdk-linux/tools/lib/sdkmanager.jar Error: The tools directory property is not set, please make sure you are executing android – Taxexempt

This is based on the assumption that you downloaded the SDK tools as an archive from Google and unpacked them into $ANDROID_HOME – Scraper

This seems the most up-to-date answer. It seems --licenses does not exist anymore. Note: to see list of possible versions that can be provided: $ANDROID_HOME/tools/bin/sdkmanager --list – Chatav

Thanks for the hint. I ended up using yes | android-sdk-linux/tools/bin/sdkmanager --licenses || true in my CI. – Areopagus

es | $ANDROID_HOME/tools/bin/sdkmanager "build-tools;28.0.3" -> changing the version worked for me . Thanks ! – Antiphon

Answer 6

If you are using Jenkins, you can use the following bash script as first step in the build process:

(while sleep 3; do echo "y"; done) | $ANDROID_HOME/tools/android update sdk -u

This will of course install ALL available updates, but it will save you some time if you can spare the disk space. The sleep is to avoid the broken readline in the installation program, since "yes" does not work properly in this case.

EDIT: You also need to add the "Install Android project prerequisites" plugin in the build step to get the correct $ANDROID_HOME if you are using the built-in SDK manager.

Seville

I add your line of code before "cordova platform add android" in my jenkins build which is running on Ubuntu but still getting following error : BUILD FAILED in 7s Error: /var/lib/jenkins/workspace/qa_global_php/platforms/android/gradlew: Command failed with exit code 1 Error output: FAILURE: Build failed with an exception. * What went wrong: A problem occurred configuring root project 'android'. > You have not accepted the license agreements of the following SDK components: – Sevigny

[Android SDK Build-Tools 26.0.2]. Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager. – Sevigny

"The sleep is to avoid the broken readline in the installation program" <- What does that mean? – Docia

That android tool is deprecated – Skiver

Answer 7

We found same issue building the project on Jenkins. With buildToolsVersion '25.0.2', we must accept licenses before building. In our case, we needed to run:

yes | sdkmanager --update that accepts licenses for the sdkmanager itself, and then

yes | sdkmanager --licenses that accepts new licenses not previously accepted

Remember: run these commans with the same user that jenkins does. In our Debian, the Jenkins user is just jenkins. In other words: doing it as root will create the accepted licenses as root, so Jenkins will not be able to read them.

By the way, we found sdkmanager at /var/lib/jenkins/tools/android-sdk/tools/bin. If yours is not there, find it with find / -name "sdkmanager"

Cult

this one solved the issue in my case too (build tools 26.0.x), with Jenkins in Docker. Thanks! – Southbound

Unfortunately this does not include the "automatically" part of the question. – Chemotropism

@Chemotropism thanks for your comment! I've updated the question to match with last version feature to automatically accept all licenses without human intervention. – Cult

@Maruf install the Android SDK and add it to the path :·) – Cult

Answer 8

this solved my error

echo yes | $ANDROID_HOME/tools/bin/sdkmanager "build-tools;25.0.2"

Pray

To save a few characters, yes | $ANDROID_HOME/tools/bin/sdkmanager "build-tools;25.0.2" does the same thing. – Platitudinous

Answer 9

Unfortunately the way as OP originally solved it does not always work. If you find from the error message what is your builds current build-tools version. It could be that it is a higher version of build-tools that is missing. In that case you need to manually start SDK Manager and add the build-tools and accept license.

Per OP instructions, it look as follows.

$ ./gradlew build

 
To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: https://docs.gradle.org/2.14.1/userguide/gradle_daemon.html.

NOTE: 2017-04-16

Answer 10

The android tool is deprecated and you should use the sdkmanager instead. sdkmanager also writes the licenses file when you first accept it. The license changes depending on which SDK you are using so even though the command

echo -e "\n8933bad161af4178b1185d1a37fbf41ea5269c55" > "$ANDROID_SDK/licenses/android-sdk-license"

works on some systems. It won't work on all. Some SDK installs expect to license file to end without a newline in the file so try adding a -n to the echo command.

echo -n -e "\n8933bad161af4178b1185d1a37fbf41ea5269c55" > "$ANDROID_SDK/licenses/android-sdk-license"

If that isn't working you can try using the base64 encoding instead.

So to discover my license:

$> rm ${ANDROID_HOME}/
$> unzip tools_r25.2.3-linux.zip -d ${ANDROID_HOME}
$> ${ANDROID_HOME}/tools/bin/sdkmanager "system-images;android-23;default;x86_64"

It'll prompt you to accept the license. After accepting it'll copy it to ${ANDROID_HOME}/licenses/android-sdk-license. To ensure you always get exactly what is written use base64.

$> base64 ${ANDROID_HOME}/licenses/android-sdk-license
Cjg5MzNiYWQxNjFhZjQxNzhiMTE4NWQxYTM3ZmJmNDFlYTUyNjljNTU=

Then you can use base64 -d recreate the file exactly.

$> echo Cjg5MzNiYWQxNjFhZjQxNzhiMTE4NWQxYTM3ZmJmNDFlYTUyNjljNTU= | base64 -d > ${ANDROID_HOME}/licenses/android-sdk-license

You can verify if the file written is what is expected by running a sha1sum on it.

$> sha1sum ${ANDROID_HOME}/licenses/android-sdk-license

Answer 11

if you run yes | sdkmanager --licenses, then we print content of $ANDROID_HOME/licenses/android-sdk-license,

we will get this

# cat $ANDROID_HOME/licenses/android-sdk-license

8933bad161af4178b1185d1a37fbf41ea5269c55

d56f5187479451eabf01fb78af6dfcb131a6481e

For GitLab CI, to accept Android SDK Build-Tools 26.0.2 licenses, you need to run this

before_script:
  - mkdir -p $ANDROID_HOME/licenses
  - echo "8933bad161af4178b1185d1a37fbf41ea5269c55" > $ANDROID_HOME/licenses/android-sdk-license
  - echo "d56f5187479451eabf01fb78af6dfcb131a6481e" >> $ANDROID_HOME/licenses/android-sdk-license

Plucky

You're second echo is going to the same $ANDROID_HOME/licenses/android-sdk-license is this intended? ie. appending – Bottom

@RyanR, yes, the second echo is appending, Android SDK Build-Tools 26.02 added a new license sha1 string – Plucky

I'm using bitbucket pipelines, but the concept seems to be the same as with GitLab CI. Your answer helped me understand the whole process better. Thanks! – Ravel

@Ravel I'm also using Bitbucket Pipelines and found myself here when we upgraded to Build-Tools 26.0.2 and our build broke. My end solution was to simply do yes | sdkmanager --licenses. No echos needed and this is future proof. – Bottom

@Ryan You mean I can just add 'yes | sdkmanager --licenses' to the pipeline.yml? That would be great! – Ravel

Doesn't work for me. sdkmanager says unknown argument --licenses... perhaps a newer version would be required? – Ravel

I'm using the latest android sdk dl.google.com/android/repository/sdk-tools-linux-3859397.zip. Here's my Dockerfile: git.io/vdS5k – Bottom

(Using SDK 27) since my CI is Windows-based, I did the following: copied and checked-in the whole %ANDROID_HOME%\licenses folder into the git repo as ./exported-licenses, and then in the build file I put as follows: xcopy exported-licenses %ANDROID_HOME%\licenses /s/h/e/k/f/c/y/i – Severn

This worked for my non-production build, but production complains I haven't accepted all licenses. Is there something I'm missing? – Heeled

Answer 12

Note that for anyone coming to this question currently, build-tools-24.0.2 is (I think) now considered obsolete, so you'll get:

 Error: Ignoring unknown package filter 'build-tools-24.0.2'

when running the various commands that have been suggested to install them.

The solution is to add --all:

android update sdk --no-ui --all --filter "build-tools-24.0.2"

Also if you're on 32bit linux, everything after build tools 23.0.1 is 64bit only, so will not run. 32bit users are stuck on 23.0.1, the only way to get a later build tools is to switch to 64bit.

Woodrow

Yeah, build-tools was just bumped to 25.0.1. – Precise

Your solution was the only thing I could find to work on a headless ubuntu 16 machine for build-tools-25 and gradle 4 – Undershorts

Answer 13

If you use tools/bin/sdkmanager --licenses you still need to have a human interaction. I have the problem using my gitlab CI. This is my solution:

wget --quiet --output-document=tools.zip https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip
unzip -qq tools.zip
echo y | tools/bin/sdkmanager "platforms;android-25"
echo y | tools/bin/sdkmanager "platform-tools"
echo y | tools/bin/sdkmanager "build-tools;25.0.2"
echo y | tools/bin/sdkmanager "extras;android;m2repository"
echo y | tools/bin/sdkmanager "extras;google;m2repository"

echo y will say yes if there is any question, but you need to make one line per installe package

Estrada

Still quite relevant after several months. Thank you. You saved my day :) – Gargantuan

This was helpful for me, also using GitLab – Surfboarding

Answer 14

You can also just execute:

$ANDROID_HOME/tools/bin/sdkmanager --licenses

And in Windows, execute:

%ANDROID_HOME%/tools/bin/sdkmanager --licenses

Adcock

Answer 15

Ok FOR ANYONE HAVING THIS ISSUE AS OF 2018. The above answers did NOT work for me at all. What DID work was opening Android SDK - clicking the DOWNLOAD button on the tool bar and selecting the appropriate packages. After they finish downloading, it will let you accept the license agreement.

Rightful

Answer 16

In Android Studio for Windows, the solution is as follows:

Go to File -> Settings -> Appearance & Behaviour -> System Settings -> Android SDK -> SDK Tools -> check Google Play Licensing Library -> Click Apply, and then Ok

After the installation, build your application. It will work.

Answer 18

Note: This is only for Mac users

I had same issue but none of the answers posted helped since there was no tools folder present in Library/Android/sdk. (I'm using Android 3.6.3 on Mac OS 10.14.4)

Below steps helped me to overcome licensing problem error:

1. Open Android Studio
2. Press cmd + shift + A. This opens Actions pop-up window.
3. Search for SDK Manager and hit enter to open.
4. This opens pop-up for Android SDK. Select some other version of Android apart from already installed one. (In my case Android 10.0 was already installed so I selected Android 9.0)
5. Then select Apply button. This will install corresponding SDK.

6. Now run your app it should work without any exception.

Richardo

Answer 19

For those having issues with the command line SDK, the reason it won't find the licenses you have accepted is because they have have been written to a different location than $ANDROID_HOME/licenses which is where they need to be.

I found the easiest solution was to accept the licenses like this:

$ANDROID_HOME/bin/sdkmanager --licenses --sdk_root=$ANDROID_HOME

Note: This assumes you've set ANDROID_HOME to point to wherever your sdk is installed.

Deckle

Answer 20

I solved this problem by creating a public git repo with the accepted license files. Then I use wget to fetch these licenses on any machine I need into a [sdk-dir]/licenses directory before running ./gradlew to build my project.

Americanist

Unfortunately, your solution doesn't tell me how to solve the problem. Can you share how you obtained the "license files"? – Albemarle

@FrederickNord Licenses are obtained from your $ANDROID_HOME/sdk/licenses on your computer. – Americanist

cd C:\Users\username\AppData\Local\Android\sdk\tools\android\Sdk\tools\bin

then run sdkmanager --licenses command, it asks to accept licenses.

Answer 24

In Windows PowerShell, you can do

for($i=0;$i -lt 30;$i++) { $response += "y`n"}; $response | sdkmanager --licenses

This is much more flexible and requires zero manual intervention. The 30 number is arbitrary, should be enough to cover the number of license acceptances, but can be increased if needed

Great answer, this worked for me still in 2023. Running above command allowed me to accept all licenses, then I was able to use sdkmanager to install all the packages I needed without issue. – Mahon

Answer 25

I finally found a solution on Windows, to have a real silent and automatic install:

On Windows, the following syntax doesn't work:

echo y | sdkmanager --licenses

It seems the "y" aren't correctly sent to the java program called in the batch.

The workaround is to create a file file-y.txt with several "y", one by line, and to use

call sdkmanager --licenses < file-y.txt

This will create the needed files in the licenses directory. The problem is probably related to the use of BufferedReader in Java

Here is my Docker setup.
You can follow from a plain Linux environment.

Note that yes | and --licenses --sdk_root=${ANDROID_HOME} clauses.
It seems sdkmanager --update reverts agreements, so yes | is appeared twice.

Answer 28

Download the SDK manager from this link. Then unzip and use the following command in terminal.

!tools/bin/sdkmanager --sdk_root=/usr/lib/android-sdk --licenses <<< $'y\ny\ny\ny\ny\ny\ny\n'

Copy the entire licenses/ directory and paste it into the Android SDK home directory on the machine where you wish to build your projects.

https://developer.android.com/studio/intro/update.html#download-with-gradle

this resolved the issue for me

Damiandamiani

Answer 30

I had the same error while using Cordova.

The problem was due to the fact that I installed Android Sdk through Android Studio and through apt with apt install android-sdk adb. And Cordova was calling the files installed through apt instead of the files in my home directory.

It worked once I changed the path to SDK in bash:

# Change path
export ANDROID_HOME="$HOME/Android/Sdk/"
echo "Android home = $ANDROID_HOME"
# Accept licenses
eval "${ANDROID_HOME}/tools/bin/sdkmanager --licenses"
# Run Cordova
cordova build android

Then I removed the system files that weren't used anymore: apt remove android-sdk adb.

Answer 31

You can accept all the license by executing the following command:

 sdkmanager --licenses

This will prompt you through each licenses you haven't accepted yet and you can just enter y to accept each of them.

Answer 33

I have faced two errors while Build my project on Android Studio:

1. License for package Android SDK Platform 28 not accepted. (while Build my project in Android Studio 4.1)

2. exception in thread main java.lang.noclassdeffounderror javax/xml/bind/annotation/xmlschema (while running SDK manager to accept license)

For me, it was a java version problem. I have installed JDK instead of java. TO SOLVE THE ISSUE, I did the following steps.

For Windows:

Step1: Download and install the latest JAVA version from https://www.java.com/en/download/

Step2: Search for "View advanced system settings" in the start menu button (windows icon)

Step3: Click on "Environment Variables"

Step4: under "System variables" click on "New", now set "Variable name: JAVA_HOME" and "Variable value: C:\Program Files\Java\jre1.8.0_271" (add latest installed java path here). Then "OK", "OK", and "OK".

Step5: open cmd as an administrator and type the following commands:

1. cd C:\Users\kevin\AppData\Local\Android\Sdk\tools\bin (*change username here)

2. sdkmanager --licenses

Press "y" for all questions.

Step6: Restart your Android Studio again.

DONE.

Let me know if anyone having a problem while following the above steps.

Answer 34

As of July 2019, the easiest method is to use: flutter doctor --android-licenses in the command prompt.

It proceeds to display the unaccepted T&C of SDKs one by one and you're given option to choose 'y/n'. Choose y for all.

Alternately, when you run flutter doctor, it will run Android toolchain diagnostics which displays how many licenses are not yet accepted, and suggests you to run it with the --android-licenses flag.

I was going to downvote but I am going to make a comment. This is only valid if you have flutter or you are developing with flutter, which is not the case of the OP. sdkmanager is the right way as it is generic enough as it covers everyone that has the Android SDK. – Dihedral

Answer 35

This path has been changed in the recent versions. ./sdkmanager is now in /Library/Android/sdk/cmdline-tools/latest/bin and then just do

./sdkmanager --licenses

Answer 36

If your "tools" folder is missing on MacOS, then you can do the following-

1. Use command+shift+A to open actions in Android Studio (the shortcut may vary)
2. Search for "SDK Manager"
3. Go to "SDK Tools"
4. Check Android SDK Platform Tools and click apply.

The tools folder should now appear.

Error: Unknown argument --licenses – Vitriform

Answer 42

I had this issue and I though that these answers didn't help then I figured out that my environment variables wasn't correct, although I was able to do sdkmanager command anywhere, so make sure that the environment variable is set correctly:

1. In the environment variables define a new variable with ANDROID_SDK_ROOT as a name and give it a value of where the sdktools are located eg.: C:\Android\sdk\

2. Edit your path to add the created variable to be %ANDROID_SDK_ROOT%\tools\bin\ restart you cmd.

3. Run the command that where mentioned in the answers: sdkmanager --licenses

4. Install the desired packages using sdkmanager "packageName".

Welldone

Answer 43

Turns out if you didn't install any SDK, Android Studio also shown "you haven't accept the license"...Such deceiving message, normal people would assume it implied SDK were already installed but anyway. In the Studio's SDK manager, you can just manually select the missing sdk to download and install and it handles license too. You just need to restart the Android Studio.

Here is a YT video showing your where SDK manager is.

Answer 44

On Windows, with sdkmanager in your PATH and WSL installed and configured, the following one-liner should work with every default distro (in fact I can't think of a counterexample):

wsl --exec yes "y" | sdkmanager --licenses

If that's not enough, you might want to look at this script (disclaimer: it's mine).

Matelote

Answer 45

I did successfully accept the license with the command

sdkmanager --sdk_root=$ANDROID_HOME --licenses

HOWEVER, the license was not saved anywhere. I would run the above command many times to accept all licenses but kept asking for them again. So the solution was to simply add sudo to the command...

sudo sdkmanager --sdk_root=$ANDROID_HOME --licenses

Thie successfully generated multiple license files under $ANDROID_HOME/licenses

FOR REACT NATIVE APPs:

If you are having this problem for a React Native app, in addition to above mentioned steps, make sure you have the local.properties file in the android directory(AppName/android) of your app which points to your 'sdk' directory:

sdk.dir=/PATH_TO_SDK/

Setting your android_home variable properly works for react native apps as well. Personally, I set it in my IDE run configuration. – Ragin

Answer 49

I got the same error of license not accepted...trying to set up android environment to run a React-native app in android emulator for API level 23.

I did the following:

Based on the link https://developer.android.com/studio/intro/update#download-with-gradle

Verified if the license got downloaded via the Android studio 3.1.3's SDK manager.

Set up ANDROID_HOME as C:\\Android\Sdk

(it was installed in C:\Users\username\AppData\Local\Android\Sdk)

The error got resolved after retrying the build in a new command prompt.

Answer 50

After trying many the possible solutions mentioned by members from the community I just found there might have been different problems overtime so most of the solutions are outdated.

Currently, and as I posted in the Travis community, Travis should be accepting all the licenses by default, but it kept complaining about not accepting the licenses 27.0.3 which shouldn't happen.

Adding:

before_install:
  - yes | sdkmanager "build-tools;27.0.3"

should fix the problem, we we would be able to even use an a 3.+ version of Android Gradle Tools without needing to even declare what version of build-tools we are using:

android:
  components:
    # Use the latest revision of Android SDK Tools
    - tools
    - platform-tools
    - tools

    # The SDK version used to compile your project
    - android-${ANDROID_API}
    # - build-tools-28.0.3    # WE DONT NEED THIS ANYMORE FROM AGP 3.+

    # Additional components
    - extra-google-google_play_services
    - extra-google-m2repository
    - addon-google_apis-google-${ANDROID_API}

This works as October 29th, 2018. Travis might make changes in the future so good luck with that!

Answer 51

I've spent a half day to looking for solution for Bitbucket Pipelines

If you are using Bitbucket Pipelines and you have the issue with accepting all SDK licences, try to use this code in your .yml file:

image: mingc/android-build-box:latest

pipelines:
  default:
  - step:
      script:
        - chmod +x gradlew
        - ./gradlew assemble

It should works.

All I had to do is yes | sdkmanager --licenses > /dev/null, and everything was accepted, and no huge output on the console or travis log or wherever. It also works like yes | sdkmanager "tools" > /dev/null for example.

Answer 56

You have not accepted the license agreements of the following SDK components: [Android SDK Build-Tools 24, Android SDK Platform 24]. Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager. Alternatively, to learn how to transfer the license agreements from one workstation to another, go to http://d.android.com/r/studio-ui/export-licenses.html

Uninstall and Reinstall the Android SDK Platform 24 and then the License agreements will appear, Accept the agreements and the problem will be solved!

Answer 57

In window this problem can be solved as: Open CMD in window run this command in CMD

Answer 58

I solved this because I can't use the UI. It's for pipelines in Azure. (Windows) none of the answers worked for me, but the @moobyfr posting with file-y.txt pointed me in the right direction

This works on the fresh install. You don't need to use Android Studio at all or any UI.

1. Create C:\AndroidTest
2. Create ENV variable called ANDROID_SDK_TOOLS with path from #1
3. Create ENV variable called JAVA_HOME and give it the folder path
4. open up CMD in Admin mode and go to C:\Android
5. curl --output test.zip https://dl.google.com/android/repository/commandlinetools-win-8092744_latest.zip
6. Use your favorite command line to extract the zip into the same folder
7. Navigate to the bin folder ( cmdline-tools\bin )
8. In this folder, create a file like mentions in another answer. file-y.txt and add a bunch of y's. Basically type y on each line. I did 20. So you have 20 lines with 1 y on each
9. sdkmanager "platform-tools" "platforms;android-29" --sdk_root="C:\AndroidTest\cmdline-tools\bin" < file-y.txt

This will download all the sdk's you need without the need for gradle/AndroidStudio/Xamarin. It's great for pipelines to download entire SDK support on the fly

If you have an issue, you need to type sdkmanager --licenses --sdk_root="C:\AndroidTest\cmdline-tools\bin" < file-y.txt
But, I doubt so.

Answer 59

In your Gitlab/GitHub pipeline you can:

echo y | android-sdk-mobile/cmdline-tools/bin/sdkmanager --sdk_root=android-sdk-mobile/cmdline-tools "platforms;android-${ANDROID_COMPILE_SDK}";
echo y | android-sdk-mobile/cmdline-tools/bin/sdkmanager --sdk_root=android-sdk-mobile/cmdline-tools "build-tools;${ANDROID_BUILD_TOOLS}";

Mechanistic

Answer 60

There are 2 approach that I can found to this problem.

1. Update sdk tools with command window by accepting licence agreement as follows, just change the version according to your need.

   android update sdk --no-ui --filter build-tools-25.0.2,android-25,extra-android-m2repository

2. Second approach is copying licence folders to Android root directory. Goto your development machine open Android Studio. Find your sdk location from Project Structure menu. (C:\Users\UserName\AppData\Local\Android\sdk). Under that directory there must be a licence folder. Copy that folder with the content. Paste that folder in your Jenkins server machine (or where you face with this problem) under android sdk root folder. (C:\Users\UserName.jenkins\tools\android-sdk)
