问题描述
我试图通过A2DP / AVRCP发送的轨道信息。眼下,音乐是完美的串流播放,但在接收器(即:汽车音响),跟踪信息屏是空白的(这是不使用颇受玩家在那里的情况下)。你知道吗?
I'm trying to send track informations via A2DP/AVRCP. Right now, music is perfectly streamed, but on the "receiver" (ie: car audio), the "track informations screen" is blank (which is not the case using popular players out there).Any idea ?
推荐答案
这code为我工作:
private static final String AVRCP_PLAYSTATE_CHANGED = "com.android.music.playstatechanged";
private static final String AVRCP_META_CHANGED = "com.android.music.metachanged";
private void bluetoothNotifyChange(String what) {
Intent i = new Intent(what);
i.putExtra("id", Long.valueOf(getAudioId()));
i.putExtra("artist", getArtistName());
i.putExtra("album",getAlbumName());
i.putExtra("track", getTrackName());
i.putExtra("playing", isPlaying());
i.putExtra("ListSize", getQueue());
i.putExtra("duration", duration());
i.putExtra("position", position());
sendBroadcast(i);
}
呼叫bluetoothNotifyChange与这取决于您的播放状态相应的意图(如上定义):暂停/播放/元数据更改
Call bluetoothNotifyChange with the appropriate intent (defined above) depending on your playback status: pause/playing/metadata changed.
