Android 文件上传 使用AsyncHttpClient开源框架

public void upload(View view) {

        AsyncHttpClient client = new AsyncHttpClient();

        RequestParams requestParams = new RequestParams();

        File file = new File("/sdcard/NTUSER.DAT.LOG");

        try {

            requestParams.put("file", file);

        } catch (FileNotFoundException e) {

        }



        client.post("http://10.0.2.2:8080/FileUploadServlet", requestParams,

                new AsyncHttpResponseHandler() {

                    @Override

                    public void onSuccess(String response) {

                        Toast.makeText(MainActivity.this, response,

                                Toast.LENGTH_SHORT).show();

                    }

                });



    }
