Capture music running in another person’s app

Question

Hello, on Facebook has a button that shows which Spotify song is running. Is there a way to do that in my app? I’ve looked for information but I can not find how to do it on Android. What I want is for him to capture inside the open title and artist of performing music.

The example below shows how to receive notifications from the running media on Spotify. For this to work you need to enable your class to receive such notifications and this is done via Androidmanifest.xml:

<receiver
    android:name="MyBroadcastReceiver"
    android:enabled="true"
    android:exported="true">

    <intent-filter>
        <action android:name="com.spotify.music.playbackstatechanged"/>
        <action android:name="com.spotify.music.metadatachanged"/>
        <action android:name="com.spotify.music.queuechanged"/>
    </intent-filter>

</receiver>

After the recipient has been registered, notifications will be sent to the receiving class.

You can receive information about which artist, album, track and duration is running.

Follow example code:

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class MyBroadcastReceiver extends BroadcastReceiver {
    static final class BroadcastTypes {
        static final String SPOTIFY_PACKAGE = "com.spotify.music";
        static final String PLAYBACK_STATE_CHANGED = SPOTIFY_PACKAGE + ".playbackstatechanged";
        static final String QUEUE_CHANGED = SPOTIFY_PACKAGE + ".queuechanged";
        static final String METADATA_CHANGED = SPOTIFY_PACKAGE + ".metadatachanged";
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // This is sent with all broadcasts, regardless of type. The value is taken from
        // System.currentTimeMillis(), which you can compare to in order to determine how
        // old the event is.
        long timeSentInMs = intent.getLongExtra("timeSent", 0L);

        String action = intent.getAction();

        if (action.equals(BroadcastTypes.METADATA_CHANGED)) {
            String trackId = intent.getStringExtra("id");
            String artistName = intent.getStringExtra("artist");
            String albumName = intent.getStringExtra("album");
            String trackName = intent.getStringExtra("track");
            int trackLengthInSec = intent.getIntExtra("length", 0);
            // Do something with extracted information...
        } else if (action.equals(BroadcastTypes.PLAYBACK_STATE_CHANGED)) {
            boolean playing = intent.getBooleanExtra("playing", false);
            int positionInMs = intent.getIntExtra("playbackPosition", 0);
            // Do something with extracted information
        } else if (action.equals(BroadcastTypes.QUEUE_CHANGED)) {
            // Sent only as a notification, your app may want to respond accordingly.
        }
    }
}
