无法将资产发送到Android Wear设备

这很棘手，但是为了被调用，数据的内容必须更改。尝试将时间戳添加到DataMap。例如

PutDataMapRequest request = PutDataMapRequest.create("/image");Asset asset = createAssetFromBitmap(bitmap);request.putAsset("profileImage", asset);DataMap dataMap = request.getDataMap(); dataMap.putLong("timestamp", System.currentTimeMillis());PutDataRequest dataRequest = request.asPutDataRequest();      Wearable.DataApi.putDataItem(mGoogleApiClient, dataRequest);
