在我的 Android 应用程序中，我想在暂停后播放或恢复播放的音乐。我的应用程序通过发送广播暂停音乐 https://stackoverflow.com/questions/5129027/android-application-to-pause-resume-the-music-of-another-music-player-app，但我无法让它播放或恢复音乐。
这是暂停的代码：
Intent i = new Intent("com.android.music.musicservicecommand");
i.putExtra("command", "pause");
sendBroadcast(i);
这是我在测试这些之后发现的。
我已经尝试并验证了这些命令可以正常工作。
// 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);
有关可用命令的更多信息：
