Question

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

Answer 1

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 config --android-sdk 'path-of-android-sdk'(only for ubuntu user)
> flutter doctor --android-licenses

Answer 2

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

Answer 3

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

Answer 4

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

flutter doctor --android-licenses

Answer 5

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.

Answer 7

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.

Answer 8

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

Answer 9

This works for me:

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

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

yes | ./sdkmanager --licenses

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 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

    X Android licenses not accepted.  To resolve this, run: flutter doctor --android-licenses

Actually what you have to run is the below command

Answer 20

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.

Answer 21

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).

Answer 22

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)

Answer 23

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
