如何让Spotify和其他Android音乐应用从意图中搜索和播放? [英] How to get Spotify and other Android music apps to search and play from an intent?

问题描述

我想创建一个 MEDIA_PLAY_FROM_SEARCH (或其他)意图，可以在任何主要的Android音乐应用中搜索并播放歌曲.我希望以下命令行可以在多个应用程序上运行:

I would like to create a MEDIA_PLAY_FROM_SEARCH (or other) intent that will search for and play a song in any major Android music app. I expected the following command line to work on multiple apps:

adb shell am start -a "android.media.action.MEDIA_PLAY_FROM_SEARCH" -e android.intent.extra.focus "vnd.android.cursor.item/*" -e query "yellow\ submarine\ by\ the\ beatles" -f 268435456

这对应于代码:

Intent intent = new Intent(MediaStore.INTENT_ACTION_MEDIA_PLAY_FROM_SEARCH);
intent.putExtra(MediaStore.EXTRA_MEDIA_FOCUS, "vnd.android.cursor.item/*");
intent.putExtra(SearchManager.QUERY, "yellow submarine by the beatles");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

这会在我的Pixel 2上启动一个选择器，其中列出了可以处理请求的不同应用.如果我选择Google Play音乐，它将播放Yellow Submarine.如果我选择Spotify，即使我有Spotify高级订阅，它也会搜索但不会播放. YouTube音乐也只进行搜索.

This launches a chooser on my Pixel 2 listing different apps that can handle the request. If I select Google Play Music, it plays Yellow Submarine. If I select Spotify, it does a search but does not play, even though I have a Spotify premium subscription. YouTube Music also does only a search.

我故意不指定查询是艺术家还是歌曲(如本例所示)，因为我想将决定权留给音乐应用.

I purposely don't specify whether the query is an artist or song (or both, as in this example), since I want to leave the determination to the music app.

如果我删除MediaStore.EXTRA_MEDIA_FOCUS extra和标志，则行为是相同的(在Google Play音乐和Spotify中):

The behavior is the same (in Google Play Music and Spotify) if I remove the MediaStore.EXTRA_MEDIA_FOCUS extra and the flag:

$ adb shell am start -a "android.media.action.MEDIA_PLAY_FROM_SEARCH" -e query "yellow\ submarine\ by\ the\ beatles"

要在任何主要音乐应用程序(即Google Assistant支持的音乐应用程序)中播放歌曲，我需要什么?

What do I need in my intent to make it play songs in any major music app (i.e., those supported by Google Assistant)?

推荐答案

我怀疑这是由于特定的Apps如何处理焦点所致. 您可以尝试以下吗?

I suspect that it is due to how the specific Apps are handling the focus. Could you try the following?

adb shell am start -a "android.media.action.MEDIA_PLAY_FROM_SEARCH" -e android.intent.extra.focus "vnd.android.cursor.item/playlist" -e query "yellow\ submarine\ by\ the\ beatles" -f 268435456

如果不成功...

adb shell am start -a "android.media.action.MEDIA_PLAY_FROM_SEARCH" -e android.intent.extra.focus "vnd.android.cursor.item/audio" -e query "yellow\ submarine\ by\ the\ beatles" -f 268435456

使用"vnd.android.cursor.item/*" 应该根据明智的选择播放一些音乐，但是它是非结构化的，因此Apps应该在可能的情况下使用更具体的搜索模式，例如播放列表/音频

Using "vnd.android.cursor.item/*" should play some music based on a smart choice, but it is unstructured and Apps should use more specific search modes when possible, e.g. playlist/audio
