I am trying to make a music player app, and I want to get the file of a song that the user selects in my app from their Google Play Music library. Is there any way I can do this? If not, is there a way to detect a song they are playing in the background, possibly from a different app, and then grab that audio file?
is there a way to detect a song they are playing in the background
Yes there is a way.
For simple check whether music is playing or not. Use
AudioManager manager = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE);
if(manager.isMusicActive())
{
// Something is being played.
}
And for getting info of songs playing in other app
public class CurrentMusicTrackInfoActivity extends Activity {
public static final String SERVICECMD = "com.android.music.musicservicecommand";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
IntentFilter iF = new IntentFilter();
iF.addAction("com.android.music.metachanged");
iF.addAction("com.android.music.playstatechanged");
iF.addAction("com.android.music.playbackcomplete");
iF.addAction("com.android.music.queuechanged");
iF.addAction("com.htc.music.metachanged");
iF.addAction("fm.last.android.metachanged");
iF.addAction("com.sec.android.app.music.metachanged");
iF.addAction("com.nullsoft.winamp.metachanged");
iF.addAction("com.amazon.mp3.metachanged");
iF.addAction("com.miui.player.metachanged");
iF.addAction("com.real.IMP.metachanged");
iF.addAction("com.sonyericsson.music.metachanged");
iF.addAction("com.rdio.android.metachanged");
iF.addAction("com.samsung.sec.android.MusicPlayer.metachanged");
iF.addAction("com.andrew.apollo.metachanged");
registerReceiver(mReceiver, iF);
}
private BroadcastReceiver mReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
String cmd = intent.getStringExtra("command");
Log.v("tag ", action + " / " + cmd);
String artist = intent.getStringExtra("artist");
String album = intent.getStringExtra("album");
String track = intent.getStringExtra("track");
Log.v("tag", artist + ":" + album + ":" + track);
Toast.makeText(CurrentMusicTrackInfoActivity.this, track, Toast.LENGTH_SHORT).show();
}
};
}
