10. 本地音乐控制功能

原名: ID3信息控制功能。用于控制手机第三方播放器。

Important

接口需要设备处于【蓝牙模式】才能生效
判断设备是否支持【蓝牙模式】

public boolean isSupportLightMode() {
    //获取RCSPController对象
    RCSPController controller = RCSPController.getInstance();
    //获取当前操作设备
    BluetoothDevice usingDevice = controller.getUsingDevice();
    if (null == usingDevice) return false;
    DeviceInfo deviceInfo = controller.getDeviceInfo(usingDevice);
    if (null == deviceInfo) return false; //设备未初始化
    return deviceInfo.isBtEnable();
}

判断设备是否处于【蓝牙模式】

public boolean isDeviceInLightMode() {
    //获取RCSPController对象
    RCSPController controller = RCSPController.getInstance();
    //获取当前操作设备
    BluetoothDevice usingDevice = controller.getUsingDevice();
    if (null == usingDevice) return false;
    DeviceInfo deviceInfo = controller.getDeviceInfo(usingDevice);
    if (null == deviceInfo) return false; //设备未初始化
    return deviceInfo.getCurFunction() == AttrAndFunCode.SYS_INFO_FUNCTION_BT;
}

10.1. 控制ID3信息流推送

JL_BluetoothManager方式

命令构造

boolean isOpenSteam = false;
CommandBase command;
if(isOpenSteam){ //打开ID3信息流推送
    command = CommandBuilder.buildSetDeviceNotifyADVInfoCmd(1);
}else{ //关闭ID3信息流推送
    command = CommandBuilder.buildStopDeviceNotifyADVInfoCmd();
}

代码示例参考通用命令处理示例

Note

ID3信息流推送开启后, 如果设备接收到ID3音乐信息, 将会在 1.3 蓝牙事件监听器 #onDeviceCommand方法回调

RCSPController方式

//获取RCSPController对象
RCSPController controller = RCSPController.getInstance();
//注册蓝牙RCSP事件监听器
controller.addBTRcspEventCallback(new BTRcspEventCallback() {
    @Override
    public void onID3MusicInfo(BluetoothDevice device, ID3MusicInfo id3MusicInfo) {
        //此处将会回调ID3音乐信息
    }
});
//enable - true : 开启, false : 关闭
//执行控制ID3信息流推送功能并等待结果回调
controller.controlAdvBroadcast(controller.getUsingDevice(), enable, new OnRcspActionCallback<Boolean>() {
    @Override
    public void onSuccess(BluetoothDevice device, Boolean message) {
        //成功回调
        //enable = true, 开启ID3信息流推送，ID3信息将会在BTRcspEventCallback#onID3MusicInfo回调
        //enable = false, 关闭ID3信息流推送
    }

    @Override
    public void onError(BluetoothDevice device, BaseError error) {
        //失败回调
        //error - 错误信息
    }
});

10.2. 获取ID3所有信息

JL_BluetoothManager方式

命令构造

CommandBase getID3MusicInfoCmd = CommandBuilder.buildGetBtSysInfoCmd(0x1ff);

代码示例参考通用命令处理示例

RCSPController方式

//获取RCSPController对象
RCSPController controller = RCSPController.getInstance();
//注册蓝牙RCSP事件监听器
controller.addBTRcspEventCallback(new BTRcspEventCallback() {
    @Override
    public void onID3MusicInfo(BluetoothDevice device, ID3MusicInfo id3MusicInfo) {
        //此处将会回调ID3音乐信息
    }
});
//执行获取ID3所有信息功能并等待结果回调
controller.getID3MusicInfo(controller.getUsingDevice(), new OnRcspActionCallback<Boolean>() {
    @Override
    public void onSuccess(BluetoothDevice device, Boolean message) {
        //成功回调
        //结果将会在BTRcspEventCallback#onID3MusicInfo回调
    }

    @Override
    public void onError(BluetoothDevice device, BaseError error) {
        //失败回调
        //error - 错误信息
    }
});
