我正在做一个无线应用（调等）
的情况：
- 当无线电在启动第一它播放音频AD，然后启动无线电（AD和收音机2个diferents流）
- 当AACPlayer当前正在播放的音乐和用户的变化站
两个问题：
- 当广告结束AACPlayer需要停下来，并与另一个URL启动
- 当用户选择其他无线电是一样的
随着AACDecoder库只有两种方法 - 启动（） - 停止（）
这些方法可以相互干扰和不确定的状态得到了玩家
我开始使用此代码玩家：
public void start(String url) throws Exception {
if (mPlayer == null) {
mPlayer = new MultiPlayer(this);
}
mPlayer.playAsync(url);
mState = StreamingState.PREPARING;
}
并停止它是这样的：
public void stop() {
if (mPlayer == null) {
return;
}
try {
mPlayer.stop();
mPlayer = null;
} catch (Exception e) {
}
setState(StreamingState.STOPPING);
}
我用这个回调接口：
static interface RadioPlayerCallBack {
public void radioPlayerStarted();
public void radioPlayerStopped(int perf);
public void radioPlayerException(Throwable e);
public void radioPlayerMetadata(String key, String value);
public void radioPlayerPCMFeedBuffer(boolean isPlaying, int audioBufferSizeMs, int audioBufferCapacityMs);
}
我更新与此枚举的播放器的状态：
public enum StreamingState {
EMPTY, // media player rested or releasedS
CREATED, // created ready to prepare
PREPARING, // preparing...
PREPARED, // prepared
STARTED, // started, and maybe playing (ready to play)
PAUSED, // paused (media player ready!)
STOPPED, // stopped and not prepared to play
ERROR, // an error occured, mediaplayer is reseted
STOPPING, // startAsync after stop
}
我无法找到一个解决方案做停止（） -在已经播放的流播放器>开始（URL），同时确保玩家的状态（我必须在考虑网络的延迟）
我怎样才能做到这一点？
编辑
下面是如何做事的快速视图：
[PlayerActivity - > StreamingService - > PlayerObject]
为了 ：
点击播放按钮 - >调用方法playRadio从StreamingService通过实例从serviceConnection->调用方法该剧从PlayerObject-> playerState =开始 - >法playerStarted自动叫 - > playerState =开始 - >从StreamingService回调方法 - >广播意图告知UI - > UI获得的意图和更新接口...
这里是广播接收器：
final private BroadcastReceiver mPlayBackReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String actionString = intent.getAction();
if (actionString == ServiceStreaming.SERVICE_PLAY) {
} else if (actionString == ServiceStreaming.SERVICE_STOP) {
} else if (actionString == ServiceStreaming.SERVICE_LOADING) {
} else if (actionString == ServiceStreaming.SERVICE_ERROR) {
} else if (actionString == ServiceStreaming.SERVICE_KILLED) {
}
}
};
