我使用ParcelFileDescriptor向连接的设备发送数据帧，但是当我检查错误日志时，我看到了这个错误。

这是我的代码段：

 private void initFramesToBeSendCallback() {
    // this is where i initiate the parcelfiledescriptor to the outputstream in the parcelfiledescriptor[1]

    outputStream = new ParcelFileDescriptor.AutoCloseOutputStream(writePfd);

     //  Camera surface callback which returns camera frames data that i use to send write it in outputstream and send to connected device
    surfaceHolder.setFramesToBeRetrieveListener(new CustomSurfaceHolder.OnCaptureFramesToBeSendCallback() {
        @Override
        public void getCurrentData(byte[] bytes) {
            if (isRecording) {
                Log.e(TAG, "initFramesToBeSendCallback RECORDING, will send data!");
                send1stArrayOfParcelFileDescriptor(readPfd);
                sendFramesOfImages(bytes);
            } else {
                Log.e(TAG, "initFramesToBeSendCallback NOT RECORDING");
            }

        }
    });
}




 private void send1stArrayOfParcelFileDescriptor(ParcelFileDescriptor fd) {
    Nearby.Connections.sendPayload(client, endpointString, Payload.fromStream(fd))
            .setResultCallback(new ResultCallback<Status>() {
                @Override
                public void onResult(@NonNull Status status) {
                    if (status.isSuccess() || status.getStatusCode() == 0) {
                        Log.e(TAG, "onResult: STREAM DATA SUCCESS send1stArrayOfParcelFileDescriptor");
                    } else {
                        Log.e(TAG, "onResult: FAILED TO SEND STREAM DATA ERROR send1stArrayOfParcelFileDescriptor CODE: " + status.getStatusCode());
                    }
                }
            });
}


private void sendFramesOfImages(byte[] bytes) {
    byteRef = bytes;

    new Thread(new Runnable() {
        @Override
        public void run() {

            try {
                outputStream.write(byteRef, 0, byteRef.length);
                outputStream.flush();
            } catch (IOException e) {
                e.printStackTrace();
                Log.e(TAG, "sendFramesOfImages: EXCEPTION SENDING PARCELFILE DESCRIPTOR[1] " + e.getMessage());
            }

        }
    }).start();

}

我不知道导致的错误是什么以及其背后的原因。我无法在谷歌搜索中找到任何相关的错误。我希望Google Devs的某些人可以帮助我。感谢
