问题描述
我的音乐应用程序不断在后台播放音乐,但是我希望能够检测到另一个应用程序何时开始播放音频(例如 YouTube 应用程序),以便我可以在我的应用程序中暂停/静音/停止音频.
这将允许用户在听音乐的同时继续浏览网页,但是如果他们想随时观看视频,他们可以在没有音频冲突的情况下进行.
一种解决方案可能是监听应用程序何时开始使用 AudioManager 的广播.是否存在这样的 Intent Action?
就像下面提供的答案一样,似乎有一种方法可以使用 AudioManager.OnAudioFocusChangeListener
检测 2.2 中音频焦点的丢失.
很好,但是对于更常见的 Android 版本有没有解决方案?最好 1.5+.

此主题还有其他信息,可能会让您朝着正确的方向前进.
My music application constantly plays music in the background, however I'd like to be able to detect when another application starts playing audio (such as the YouTube app) so I can pause/mute/stop the audio in my application.
This will allow a user to continue browsing the web whilst listening to music, but then if they wish to watch a video at any point, they can do so without audio conflict.
One solution might be to listen for a broadcast which states when an application begins using the AudioManager. Does such an Intent Action exist?
Edit: As in the answer provided below, there appears to be a method of detecting the loss of audio focus in 2.2 with AudioManager.OnAudioFocusChangeListener
.
Great, but is there a solution for the more common versions of Android? Ideally 1.5+.
