I'm new to WearOS, I need to develop an activity tracking application. I'm starting from the example provided by Google for Always-on applications. In the emulator everything works fine as can be seen from this trace:

But when I try on a real device (Suunto 7, WearOS 2.17) it does not work. When I turn the wrist, the application does not enter ambient mode, it gives this error Error on detecting ambient animation and instead of calling onEnterAmbient() it just calls onPause(). As soon as I tap the display, onResume() is called. Full trace here:

Am I doing something wrong? The code is exactly the one provided by Google here. Any clue about how to solve it? Thanks
I found the problem. To get this modality to work the display has to be set as always on in Settings -> Display -> Always-on screen. This is not really what I wanted since the Suunto app can achieve this without this modality being active, but I guess it's due to the fact that it is a system application.
