Travis CI build doesn't work with Android Constraint Layout

Question

I am trying to make Travis build my Android project. It fails when it tries to download the library for ConstraintLayout. Do you know what I have to do to make

Answer 1

Workaround to accept the license is no longer required as explained here if you directly accept it:

  - echo yes | sdkmanager "extras;m2repository;com;android;support;constraint;constraint-layout;1.0.2"
  - echo yes | sdkmanager "extras;m2repository;com;android;support;constraint;constraint-layout-solver;1.0.2"

Full working sample using constraint-layout codelab repository for Android API level 22 to 25.
