android-21-circle.yml

#
# Build configuration for Circle CI

general:
    artifacts:
        - /home/ubuntu/your-app-name/app/build/outputs/apk/

machine:
    environment:
        ANDROID_HOME: /usr/local/android-sdk-linux

dependencies:
    override:
        - echo y | android update sdk --no-ui --all --filter tools,platform-tools,build-tools-21.1.2,android-21,extra-google-m2repository,extra-google-google_play_services,extra-android-support

test:
    override:
        - (./gradlew assemble):
            timeout: 360

I have this

dependencies:
    override:
        - echo "y" | android update sdk --no-ui --all --filter tools,platform-tools,build-tools-25.0.1,android-25,extra-google-m2repository,extra-google-google_play_services,extra-android-support
        - chmod +x gradlew
        - ANDROID_HOME=/usr/local/android-sdk-linux ./gradlew dependencies

and I get the following error

A problem occurred configuring project ':android-lib'.
> You have not accepted the license agreements of the following SDK components:
  [Android Support Repository].
  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

What am I missing?

@bolorundurowb there are different licenses that need to be accepted so you need to group your packages according to their license.

dependencies:
  pre:
    - echo y | android update sdk --no-ui --all --filter "platform-tools, tools"
    - echo y | android update sdk --no-ui --all --filter "android-24, build-tools-25.0.2"
    - echo y | android update sdk --no-ui --all --filter "extra-android-m2repository"
    - echo y | android update sdk --no-ui --all --filter "extra-android-support"

I also noticed that you have echo "y" try removing the quotes surrounding y
