Ошибка эспрессо-теста на CircleCI

Я пытаюсь запустить тесты инструментария Android на CircleCI. Они отлично работают на локальном компьютере, как из Android Studio, так и из командной строки. Выполнение CircleCI создает этот стек для каждого теста:

java.lang.RuntimeException: Waited for the root of the view hierarchy to have window focus and not be requesting layout for over 10 seconds. If you specified a non default root matcher, it may be picking a root that never takes focus. Otherwise, something is seriously wrong. Selected Root: Root{application-window-token=android.view.ViewRootImpl$W@677cf28, window-token=android.view.ViewRootImpl$W@677cf28, has-window-focus=false, layout-params-type=1, layout-params-string=WM.LayoutParams{(0,0)(fillxfill) sim=#100 ty=1 fl=#81810100 wanim=0x1030466 surfaceInsets=Rect(0, 0 - 0, 0) needsMenuKey=2}, decor-view-string=DecorView{id=-1, visibility=VISIBLE, width=480, height=800, has-focus=true, has-focusable=true, has-window-focus=false, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=2}} .

Какие-либо предложения? Вот соответствующие части circle.yml:

Я связался с поддержкой CircleCI и попросил их любезно создать примерный проект с эспрессо-тестами.

Так вот оно .

Это помогло мне. Надеюсь, это вам тоже поможет.
