android - WearOS 始终开启模式无法在设备上运行

问题描述

我是 WearOS 的新手，我需要开发一个活动跟踪应用程序。我从 Google 为 Always-on 应用程序提供的示例开始。在模拟器中一切正常，从这个跟踪中可以看出：

2020-05-27 15:44:51.002 4296-4296/com.example.android.wearable.wear.alwayson D/MainActivity: loadDataAndUpdateScreen(): 1590587091002(false)

但是当我在真实设备（Suunto 7、WearOS 2.17）上尝试时，它不起作用。当我转动手腕时，应用程序没有进入环境模式，它给出了这个错误Error on detecting ambient animation，而不是调用onEnterAmbient()它只是调用onPause(). 一旦我点击显示屏，就会调用 onResume()。完整的跟踪在这里：

难道我做错了什么？该代码正是谷歌在此处提供的代码。关于如何解决它的任何线索？谢谢

解决方案

我发现了问题。要使此模式正常工作，必须在 Settings -> Display -> Always-on screen 中将显示设置为始终开启。这并不是我真正想要的，因为 Suunto 应用程序可以在不激活此模式的情况下实现这一点，但我想这是因为它是一个系统应用程序。
