Question

我正在开发一个代号为1的项目，该项目要求我录制用户语音并将其发送到服务器，该记录工作得很好，但是我什么时候将它发送到服务器它给出了一个错误。有没有人有解决它给出的错误。这是进行录制的代码。

Media media;
    String p;
    private void doRecord()
    {
        // initites devices microphone and do the recording until it is stopped.
        try{
            p = getTempFileName();
            media = MediaManager.createMediaRecorder(p,MediaManager.getMediaRecorderingMimeType());
            media.play();
        }catch (IOException ex) {
            ex.printStackTrace();
        }
    }


private String getTempFileName() {
        String[] roots = FileSystemStorage.getInstance().getRoots();
        // iOS doesn't have an SD card
        String root = roots[0];
        for (int i = 0; i < roots.length; i++) {
            if (FileSystemStorage.getInstance().getRootType(roots[i]) == FileSystemStorage.ROOT_TYPE_SDCARD) {
                root = roots[i];
                break;
            }
        }
        return root + FileSystemStorage.getInstance().getFileSystemSeparator() + "audioSample" + System.currentTimeMillis();
    }

public void stopRecord（boolean timeElapsed） { media.pause（）; media.cleanup（）;

    sendToNetwork(timeElapsed);
}

private com.codename1.io.MultipartRequest request;
public void sendToNetwork(boolean timeElapsed)
{
   request = new com.codename1.io.MultipartRequest(){
   //action performed when response is read goes here
}
request.setUrl("https://theURL");
        request.setPost(true);
        request.addArgument("int_id ",mock_session);
        request.addArgument("quesID",question_id);
        request.addArgument("mock_session",mock_session);
        request.addArgument("mock_email",mock_email);
        request.addArgument("fname","");


                    //add the data image
        request.addData("data", p,MediaManager.getMediaRecorderingMimeType());

        request.setPriority(ConnectionRequest.PRIORITY_CRITICAL);
        NetworkManager.getInstance().addToQueue(request);

}

这是我在运行时得到的错误...

java.lang.NUllPointerException: for URL https://theURL null.

可能是什么原因，有什么我不对的。

Answer 1

感谢Shai问题来自服务器，该文件已成功发送到服务器，但错误来自响应，因为我无法从模拟器测试它，因为Media无法在模拟器中工作我无法看到堆栈跟踪。已经修好了。

将录制的文件上传到服务器Codename One
