文件上传到服务器上的Android eclipse错误

Question

在我的 android eclipse 项目中，我想将带有名称和电子邮件字段的图像文件上传到服务器。

但我收到以下错误：我的 logcat 如下：

NoSuchFieldError - BasicHeaderValueFormatter.INSTANCE

E/AndroidRuntime(25348): Caused by: java.lang.NoSuchFieldError: org.apache.http.message.BasicHeaderValueFormatter.INSTANCE

我的整个日志：

我上传图片的代码和一些字段如下：

class ImageUploadTask extends AsyncTask<Void, Void, String> {
    @SuppressWarnings("deprecation")
    @Override
    protected String doInBackground(Void... unsued) {
        try {

            File image = new File(iPath);
            FileBody fileBody = new FileBody(image);

            HttpClient client = new DefaultHttpClient();
            HttpContext localContext = new BasicHttpContext();
            HttpPost post = new HttpPost(Constant.signUp);

            post.setHeader("enctype", "multipart/form-data");

            MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
            multipartEntity.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

            multipartEntity.addPart("ID", new StringBody("1"));
            multipartEntity.addPart("pID", new StringBody("1"));
            multipartEntity.addPart("userPhoto", fileBody);
            multipartEntity.addPart("email", new StringBody("joseph@gmail.com"));
            multipartEntity.addPart("cell", new StringBody("1234567890"));
            multipartEntity.addPart("username", new StringBody("joseph"));

            post.setEntity(multipartEntity.build());
            // post.setEntity((MultipartEntityBuilder) multipartEntity);
            HttpResponse response = client.execute(post, localContext);
            BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(),
                    "UTF-8"));

            HttpResponse responses = client.execute(post);
            String responseBody = EntityUtils.toString(response.getEntity());
            Log.v("multiPartPost HTTP Response", responseBody);

        } catch (Exception e) {

            System.out.println("error=" + e.getMessage());
            return null;
        }
        return "";

    }

    @Override
    protected void onProgressUpdate(Void... unsued) {

    }

    @Override
    protected void onPostExecute(String sResponse) {
        try {

            if (sResponse != null) {
                JSONObject JResponse = new JSONObject(sResponse);
                int success = JResponse.getInt("SUCCESS");
                String message = JResponse.getString("MESSAGE");
                if (success == 0) {
                    Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
                } else {
                    Toast.makeText(getApplicationContext(), "Photo uploaded successfully", Toast.LENGTH_SHORT)
                            .show();
                    caption.setText("");
                }
            }
        } catch (Exception e) {
            Toast.makeText(getApplicationContext(), "excepttion", Toast.LENGTH_LONG).show();
            Log.e(e.getClass().getName(), e.getMessage(), e);
        }
    }
}

我的 libs 文件夹有以下必要的库：

在我的 java 构建路径中：

并按顺序导出属性

现在我必须做些什么来解决这个错误：我整天都在努力解决这个问题，但没有，所以请任何人建议我如何解决这个错误，非常感谢，谢谢。

Answer 1

这是库的主要问题，所有人都可能面临，错误的库会导致此问题，

所以，以下步骤对您有帮助：

(1) 代码：以下代码成功上传照片到服务器：

     btnUpload.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            if (Constant.bitmapPicture != null) {
                StoreByteImage(Constant.bitmapPicture, 90, "my_image");

            } else {
                Toast.makeText(getApplicationContext(), "image null", Toast.LENGTH_LONG).show();
            }
        }
    });

StoreByteImage(...) :

   public boolean StoreByteImage(Bitmap bitmap, int quality, String expName) {

    FileOutputStream fileOutputStream = null;
    String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
    File myNewFolder = new File(extStorageDirectory + "/Example");
    if (myNewFolder.mkdirs()) {
        myNewFolder.mkdir();
    }
    try {


        iPath = myNewFolder + "/" + expName + ".jpg";
        fileOutputStream = new FileOutputStream(myNewFolder + "/" + expName + ".jpg");
        BufferedOutputStream bos = new BufferedOutputStream(fileOutputStream);
        bitmap.compress(CompressFormat.JPEG, quality, bos);

        new ImageUploadTask().execute();

        bos.flush();
        bos.close();

    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    return true;
}

类 ImageUploadTask

class ImageUploadTask extends AsyncTask<Void, Void, String> {

    String sResponse;

    @SuppressWarnings("deprecation")
    @Override
    protected String doInBackground(Void... unsued) {
        try {
            //

            File image = new File(iPath);
            FileBody fileBody = new FileBody(image);

            HttpClient httpClient = new DefaultHttpClient();
            HttpContext localContext = new BasicHttpContext();
            HttpPost httpPost = new HttpPost(YourImageUploadURLHere);

            MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            Constant.bitmapPicture.compress(CompressFormat.JPEG, 100, bos);
            byte[] data = bos.toByteArray();

            entity.addPart("ID", new StringBody("1"));
            entity.addPart("pID", new StringBody("1"));
            entity.addPart("userPhoto", fileBody);
            entity.addPart("email", new StringBody("email@gmail.com"));
            entity.addPart("cell", new StringBody("1234567890"));
            entity.addPart("username", new StringBody("name"));

            httpPost.setEntity(entity);
            HttpResponse response = httpClient.execute(httpPost, localContext);
            BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(),
                    "UTF-8"));

            sResponse = reader.readLine();
            System.out.println("responce=" + sResponse);

        } catch (Exception e) {

            System.out.println("error=" + e.getMessage());
            return null;
        }
        return "";

    }

    @Override
    protected void onProgressUpdate(Void... unsued) {

    }

    @Override
    protected void onPostExecute(String sResponses) {
        try {

            if (sResponses != null) {

                JSONObject jsonObjSend = new JSONObject(sResponse.toString());

                if (jsonObjSend.getString("status").equals("success")) {

                    // another code
                } else if (jsonObjSend.getString("status").equals("fail")) {

                    // another code
                }

            }
        } catch (Exception e) {
            Toast.makeText(getApplicationContext(), "excepttion", Toast.LENGTH_LONG).show();
            Log.e(e.getClass().getName(), e.getMessage(), e);
        }
    }
}

(2) 首先从您的 libs 文件夹中删除所有 libs/jar 文件：

(3) 从网上找到以下库/jar 文件并放入 libs 文件夹：

(4) 从库选项卡添加 jar：

(5) 您的订单和导出库/jar 文件勾选标记如下：

好的，完成。只是这些简单的步骤有助于您将图像文件上传到服务器。 希望这些对您和其他人有所帮助。

在我注意到这个错误之前，我已经从 4.3 升级到了 4.4。 可能是 4.3 造成的。
