Android 将资产从手表转移到手持设备

我试图复制这个函数。 手表上的发射器部件很好。在手持设备的WearableListenerService的

onDataChanged

功能中，每次

DataMapItem DataMapItem=DataMapItem.fromDataItem（event.getDataItem（））时都会发生异常被调用

例外情况如下：

public void onDataChanged（DataEventBuffer dataEvents）{
最终列表事件=Freezabluetils
.可冻结（数据事件）；
dataEvents.close（）；
如果（！mgoogleapClient.isConnected（））{

.阻塞连接（30，时间单位为秒）；
如果（！connectionResult.isSuccess（））{
Log.e（标记“WEAR:：Service未能连接到GoogleAppClient”）；
返回；
}
}否则{
Log.e（标签“WEAR:：连接到GoogleAppClient的服务”）；
}
用于（数据事件：事件）{
如果（event.getType（）==DataEvent.TYPE_已更改&&
event.getDataItem（）.getUri（）.getPath（）.equals（“/audio”））{
DataMapItem DataMapItem=DataMapItem.fromDataItem（event.getDataItem（））；
Asset audioAsset=dataMapItem.getDataMap（）.getAsset（“音频”）；
DataExchange.setBuffer（loadAudioFromAsset（audioAsset））；
Log.w（标记“接收”）；
}
}
}

有什么想法吗？
问题似乎在这里：

final List<DataEvent> events = FreezableUtils
    .freezeIterable(dataEvents);
dataEvents.close();

final List events=FreezableUtils
.可冻结（数据事件）；
dataEvents.close（）；

这是什么意思？
请显示此代码以获取详细答案。
我通过替换此代码解决了此问题

    PutDataRequest putDataRequest = PutDataRequest.create("/image");
    putDataRequest.putAsset("debugFile", asset);
    Wearable.DataApi.putDataItem(client, putDataRequest);

用这个

    PutDataMapRequest dataMap = PutDataMapRequest.create("/image");
    dataMap.getDataMap().putAsset("debugFile", asset);
    PutDataRequest request = dataMap.asPutDataRequest();
    PendingResult<DataItemResult> pendingResult = Wearable.DataApi.putDataItem(client, request);
    pendingResult.setResultCallback(new ResultCallback<DataItemResult> () {
        @Override
        public void onResult(DataItemResult dataItemResult) {
            // something 
        }
    } );

putDataMapRequestDataMap=PutDataMapRequest.create（“/image”）；
dataMap.getDataMap（）.putAsset（“调试文件”，资产）；
PutDataRequest=dataMap.asPutDataRequest（）；
Pendingreult Pendingreult=可穿戴的.DataApi.putDataItem（客户端，请求）；
Pendingreult.setResultCallback（新的ResultCallback（）{
@凌驾
公共void onResult（DataItemResult DataItemResult）{
//某物
}
} );

现在对我有用了
