"Failed to install the following Android SDK packages as some licences have not been accepted" error

I am getting this error in jitpack, I've tried everything on the internet. Below is my error

Failed to install the following Android SDK packages as some licences have not been accepted.
     platforms;android-26 Android SDK Platform 26
     build-tools;28.0.3 Android SDK Build-Tools 28.0.3
  To build this project, accept the SDK license agreements and install the missing components using the Android Studio SDK Manager.

And when i run ./sdkmanager --licenses

 All SDK package licenses accepted.======] 100% Computing updates...             

Using sudo with the above command gives

I don't know why it's checking for licenses there when my sdk location is other

You need to accept the licences before building.

According to Android SDK docs you can use the following command depending on the sdkmanager location: Docs on --licenses option seems to be missing though.

yes | sdkmanager --licenses

GNU/Linux Distributions:

yes | ~/Android/Sdk/tools/bin/sdkmanager --licenses

macOS:

export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home
yes | ~/Library/Android/sdk/tools/bin/sdkmanager --licenses

Windows:

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

Flutter:

> flutter doctor --android-licenses

In Android Studio go to Tools -> SDK Manager.

Go to SDK Tools tab.

Select the Android SDK Command-line Tools (latest) and download by pressing Apply.

On Windows, you can find the sdkmanager.bat at

C:\Users\[your_user]\AppData\Local\Android\Sdk\cmdline-tools\latest\bin

in Windows OS go to your sdkmanager path then execute

./sdkmanager.bat --licenses

You can find your sdkmanager in C:\Users\USER\AppData\Local\Android\Sdk\tools\bin

OR

For those people not using android studio on window os. Go to your cmdline-tools\tool\bin and type cmd on the directory box to open the directory in your terminal. Then run sdkmanager --licenses

To find your actual android SDK path follow the red marked area of the below picture

If you are working with Flutter then this command would definitely work for you.

flutter doctor --android-licenses

Problem: SDK license not accepted

Step 1: Open SDK Manager

After opening the SDK manager, open the SDK tools tab as shown below

Step 2: Check the option Show Package Details

It'll list out all the versions of SDK tools

Step 3: Install the required SDK tool version

Check the specific version of SDK tools that is complaining (for me, it was 29.0.3 as shown above in the first screenshot) from the list, accept the agreement in the dialog that opens next and you're done.

MacOS Catalina

Step 1: Changing Android Studio Preference

1. Open-up your Android Studio
2. Press Command+, or go to top-left AppBar Android Studio > Preferences.
3. From Left Pane, select Appearance > System Settings > Android SDK
4. Select SDK Tools next to SDK Platforms and under Android SDK Location
5. Check mark Android SDK Command-line Tools (latest) and Press OK button.
6. Wait for installation to be finished

Step 2 (For Flutter Users):

1. Go to Terminal and run the following command

flutter doctor --android-licenses

Step 2 (For Android Users):

1. Go to the Terminal and run the following command

export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home

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

You can accept the license agreements of the stated SDKs by going to the SDK Manager (Settings > [Search for Android SDK]) then find the packages noted in the error message and find them there. Chances are, you'll find SDKs that are not fully installed and installing them will ask you to accept the license agreement.

use android-28 with build-tools at version 28.0.3; or build-tools at version 26.0.3.

or try this: yes | sudo sdkmanager --licenses

This works for me:

yes | ./sdkmanager "platforms;android-28"

yes | ./sdkmanager "build-tools;28.0.3"

yes | ./sdkmanager --licenses

If you are getting this error while using Flutter then please run the below command on command prompt.

flutter doctor --android-licenses

If you get below error after running the above command

Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema
    at com.android.repository.api.SchemaModule$SchemaModuleVersion.<init>(SchemaModule.java:156)
    at com.android.repository.api.SchemaModule.<init>(SchemaModule.java:75)
    at com.android.sdklib.repository.AndroidSdkHandler.<clinit>(AndroidSdkHandler.java:81)

    at com.android.sdklib.tool.sdkmanager.SdkManagerCli.main(SdkManagerCli.java:48)

Then please do the below steps

1. Open android studio
2. Go to SDK manager
3. Click on SDK tools tab
4. Install Android SDK command line tool
5. Run flutter doctor --android-licenses again

For Android Studio Arctic Fox, it was solved for me by installing the Google Play Licensing Library.

1. Go to Preferences
2. Expand Appearance & Behavior
3. Then expand System Settings
4. Select Android SDK and go to SDK Tools tab
5. Install Google Play Licensing Library

In Android Studio go to: Tools > SDK Manager > SDK Tools

On the bottom right, check the "Show Package Details" box and download the version of sdk that you need:

Tried this on Android Studio and it worked for me:

Tools > SDK Manager (Make sure to check Show Packages below)

SDK Platforms > Show Packages > Android - 28

SDK Tools > Show Packages > 28.0.3

Appears to be a bug at the momment: https://issuetracker.google.com/issues/123054726

Solution that worked for me:

Create a .travis.yml file in your project directory and copy these lines:

before_script:
- mkdir "$ANDROID_HOME/licenses" || true
- echo "24333f8a63b6825ea9c5514f83c2829b004d1fee" > "$ANDROID_HOME/licenses/android-sdk-license"

Reference: https://github.com/square/RxIdler/pull/18/files

in Windows OS go to your sdkmanager path directory in cmd

You can find your sdkmanager in C:\Users\USER\AppData\Local\Android\Sdk\tools\bin

then execute the followwing command:

sdkmanager --licenses

after that it will ask to accept license agreement several times then accept all by just typing y on cmd

This works for me in Windows 10:

C:
cd \Users\YOUR_USER\AppData\Local\Android\Sdk\cmdline-tools\latest\bin
sdkmanager.bat --licenses

After, yes to all

On Mac OS 10.15.1, I got the same error even after accepted all the licenses by running sdkmanager --licenses It worked after I updated the ANDROID_HOME path configuration in the ~/.bash_profile to the following

export ANDROID_HOME=/Users/your_username/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
export PATH=$PATH:~/Library/Android/sdk/platform-tools

And reload the ~/.bash_profile

source ~/.bash_profile 

I tried many solutions but didn't work for me. The below solution works for me.

locate the sdkmanager file in android SDK.

In my case : ~/Android/Sdk/tools/bin

go to that path : cd ~/Android/Sdk/tools/bin

Accept licenses manually : ./sdkmanager --licenses Enter Yes or y

If you are using flutter go with the following steps

1.open the command prompt

Then the following command

2.C:\Users\niroshan>flutter doctor

And you will see the issues as follows

Actually what you have to run is the below command

C:\Users\niroshan>flutter doctor --android-licenses

https://www.youtube.com/watch?v=g789PvvW4qo really helped me. What had done is open SDK Manager and download any new SDK Platform (dont worry it wont affect your desired api level).

Because with downlaoding any SDK Platforms(API level), you should accept licences. That's the trick worked for me.

I had the same problem when trying to run an app on my android device in a different project where I was working with some old version of tomcat8 and had to set the JAVA_OPTS variable and value. So I removed this system variable for JAVA_OPTS, which had a Variable value set to -Xms1024m (Remove the JAVA_OPTS system variable, but you can also store it for future use if you need to revert to using your old projects that might need it).

Then run the SDK manager bat file in your sdk path: PS C:\Users[your_pc_username]\AppData\Local\Android\Sdk\tools\bin> .\sdkmanager.bat --licenses

Accept all licenses (Y).

How I solve this problem (AndroidStudio 4.2)

• Click in Build tab
• Select Failed to install the following Android SDK packages ... (warning)
• Click Install missing SDK package(s)

On Ubuntu it still didn't work using the answers suggested.

This is what worked for me:

cd full-path-to-bin folder, where sdkmanager is located.

yes | ./sdkmanager --licenses --sdk_root="full-path-to-bin"

In the option --help it shows we can pass common args to it, which finally accepted ALL licences:

Usage:
...
sdkmanager --licenses [<common args>]
...
Common Arguments:
    --sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK containing this tool

To add to the answers, you can also change to the sdkmanager directory and in a sub shell and accept the licenses there

(
	cd /home/user/android-sdk-linux/tools/bin
	yes | ./sdkmanager --licenses
)

I just done File -> Invalidate caches and restart Then install missing packages. Worked for me.

On Windows:

1. Add USER Environment variables:

NOTE: Path should be appended

JAVA_HOME			%ProgramFiles%\Android\Android Studio\jre
ANDROID_SDK_ROOT	%LocalAppData%\Android\Sdk
Path				%LocalAppData%\Android\Sdk

2. Run the below command to accept licenses:

NOTE: Accept all licenses (say y)

%ANDROID_SDK_ROOT%/tools/bin/sdkmanager.bat --licenses

3. Now run your app:

(like below, or another command that failed for you):

cd \myapp\
react-native run-android

in my case I just installed a new version of android studio on a new laptop and cloned the old repository where buildToolsVersion "30.0.2" at application level build.gradle. I just upgraded to 30.0.3 which android studio recommended on its own and the problem went away

I moved my Sdks and Avds folder as it was using lots of memory in local disk c, but after that I got the above issue.

For me Invalidate Caches/Restart solve the issue

File->Invalidate Caches/Restart

In my case updating buildToolsVersion in app level build.gradle worked perfectly. If you don't know which to use you can create new project and copy buildToolsVersion from that into existing one.

A one liner solution with downgrade to java 8:

sudo apt-get install openjdk-8-jdk -y && export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 && flutter doctor --android-licenses

Just visit to the Build.gradle(Module Appname.app) here, find the "buildToolsVersion" and change the version to "32.0.0"
