停止音乐应用程序播放音乐 [英] Stop the music app to play music

我搜索周围，但没有找到任何答案。我想我的应用程序，如果有音乐播放应用程序的音乐（如谷歌音乐），我的应用程序停止播放音乐。那可能吗？

I've searched around but haven't found any answers. I want my app, if there is music app playing music (e.g Google Music), stop the playing music from my app. Is that possible?

推荐答案

这取决于所使用的音频播放器。你可能能够控制一些，但其他可保持免疫。借助内置的一个，你可以试试这个code

It depends on audio player being used. You may be able to control some, but other may remain immune. With built-in one, you can try this code

public static final String SERVICECMD = "com.android.music.musicservicecommand";
public static final String CMDNAME = "command";
public static final String CMDSTOP = "stop";

AudioManager mAudioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);

if(mAudioManager.isMusicActive()) {
    Intent i = new Intent(SERVICECMD);
    i.putExtra(CMDNAME , CMDSTOP );
    YourApplicationClass.this.sendBroadcast(i);
}

其他命令

public static final String CMDTOGGLEPAUSE = "togglepause";
public static final String CMDPAUSE = "pause";
public static final String CMDPREVIOUS = "previous";
public static final String CMDNEXT = "next";
