Android Epresso: DatePicker Click on OK add a year instead of validate

Issue

In an Google Espresso test, I'm trying to click on the OK button of a DatePickerDialog.

But instead of validating my input, it just add a year and does not close the dialog.

It seems that the click is done on the "+" button of year's column. Is that an Espresso bug or am I missing something?

Here is my Espresso code (in Kotlin):

onView(allOf(iz(instanceOf(javaClass<Button>())), withText("OK"),
            isDisplayed()) as Matcher<View>).perform(click())

Solution

After upgrading my testing device to 4.4.4, the bug has gone by itself: it was an Android < 4.4 bug T_T
