@rkistner Mmmh, reading your [.travis.yml](https://github.com/embarkmobile/android-maven-example/blob/master/.travis.yml):

>   # Install required components.
  # For a full list, run `android list sdk -a --extended`
  # Note that sysimg-16 downloads the ARM, x86 and MIPS images (we should optimize this).
  # Note that `echo y` only accepts the first license. This is actually convenient, since
  # it prevents the installation of the ATOM and MIPS emulator images. It might cause
  # issues in the future though.

Could you please confirm what should be installed (beside the license prompt issue) ? in travis-ci/travis-worker#56, you said:

> Installing the Android SDK is the biggest pain point currently. The --filter option is not adequate to install specific packages, and some filters stop working when new SDK versions are released. Having all / most recent SDK components pre-installed should solve this.

Should we use `--filter` or not?
