onApplyWindowInsets is not called in CanvasWatchFaceService.Engine

Question

I am developing a watch face using CanvasWatchFaceService.Engine

I need to detect if watch is round or square.

I overrided onApplyWindowInsets, but it is not called.

Shall I set a specific listener or something like that?

Answer 1

In my experience, onApplywindowInsets only gets called when you're using Theme.DeviceDefault, or a theme descending from it. It won't get called if you're using a completely custom theme.

So in the manifest for your watch face, your application tag needs to look something like this:

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.DeviceDefault" >

Or if you have a theme for the watch face service, that will override it.

Answer 2

In my experience, onApplyWindowInsets is not called unless android:

isScrollContainer = "true"

is set to any view in layout.
