To not depend on the app locale, you can use the code from Matt Logan by replacing "Navigate up" with R.string.abc_action_bar_up_description:

onView(withContentDescription(R.string.abc_action_bar_up_description)).perform(click());
This helped me a lot because I have an app in more than 5 languages and I had to act like this.
