将我的应用定义为 Google 助理的默认音乐服务

Define my app as Google Assistant's default music service

我正在开发 Android 音乐播放器应用程序。我想将它与 Google 助手集成,以语音控制播放和搜索歌曲。 我已经根据 official documentation.

的说明在我的应用程序中实现了媒体会话

当请求 Google 助理在我的应用中播放某些内容时,我必须说 "Play some artist on MyApp" 之类的话。当我说 "Play some artist" 时,助理告诉我我没有配置默认音乐提供商。

这会将我带到 Google 助手应用程序中的以下屏幕:

我注意到 MyApp 未在 "Your music services" 中列出。 我的问题如下:我必须在我的应用程序中更改什么才能将其选为默认音乐服务?

供您参考,这是清单文件:

Google 助手目前允许列表中的某些合作伙伴应用。合作伙伴我不确定你到底在做什么。如果您在一家大型音乐提供商公司工作,您可能已经有一位 Google 业务开发代表,他应该能够将您与合适的人联系起来。

如果您还没有以某种方式与 Google 联系,此页面上有各种联系选项:https://developers.google.com/actions/ 在 "Get the support you need from day one" 部分。我会尝试这些或更多,希望能帮助您找到合适的团队。
