Answer

The solution is:

add line on top:

sudo: false

Create Emulator Management: Create, Start and Wait

before_script:
  - echo no | android create avd --force -n test -t android-21 --abi armeabi-v7a
  - emulator -avd test -no-skin -no-audio -no-window &
  - android-wait-for-emulator
  - adb shell input keyevent 82 &

Now Travis CI works.
