How to play or resume music of another music player from my code

问题

In my Android app I want to play or resume the played music after I pause it. I got my app to pause the music by sending a broadcast, but I can't get it to play or resume the music.

Here is the code to pause:

Intent i = new Intent("com.android.music.musicservicecommand");
i.putExtra("command", "pause");
sendBroadcast(i);

Here is what I have discovered after testing these.

I have tried and verified these commands to work just fine.

// pause
Intent i = new Intent("com.android.music.musicservicecommand");
i.putExtra("command", "pause");
sendBroadcast(i);

// play
Intent i = new Intent("com.android.music.musicservicecommand");
i.putExtra("command", "play");
sendBroadcast(i);

// next
Intent i = new Intent("com.android.music.musicservicecommand");
i.putExtra("command", "next");
sendBroadcast(i);

// previous
Intent i = new Intent("com.android.music.musicservicecommand");
i.putExtra("command", "previous");
sendBroadcast(i);

Some more info about available commands:

public static final String SERVICECMD = "com.android.music.musicservicecommand";
public static final String CMDNAME = "command";
public static final String CMDTOGGLEPAUSE = "togglepause";
public static final String CMDSTOP = "stop";
public static final String CMDPAUSE = "pause";
public static final String CMDPLAY = "play";
public static final String CMDPREVIOUS = "previous";
public static final String CMDNEXT = "next";

Try to use

Intent i = new Intent("com.android.music.musicservicecommand");
i.putExtra("command", "togglepause");
sendBroadcast(i);

Update

Try with the following action :

Intent i = new Intent("com.android.music.musicservicecommand.togglepause");
i.putExtra("command", "togglepause");
sendBroadcast(i);
