[android] "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

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

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

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

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.

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

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

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

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"

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.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

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

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

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

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

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

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
)

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 

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.

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.

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
