如何在android中从php获取分辨率图像

我想从服务器中的config.php获取宽度和高度， 我把这个问题弄糊涂了

这是Android任务的代码

public class task_list_todo extends DroidGap {
private navigasi_uuy mc;
public static String current_form = ""; 
private String userid = "";
private String root_url = "";
public static String last_barcode="";
public static String task_type = "";
public static String data_task = "";

public static String latlong ="";
public static String cellid="";
public static String gps_time="";
public static String gps_criteria="";
public static Boolean must_get_location = false;
private static Boolean dapet_gps = false;

public static String asal_form = "";
public static String nama_folder = "";
public String taskid = "";
public String barc = "";
public String remark = "";
public String halaman = "12121212";
public static String photo_id = "";
public static String id_task  = "";
public static String atf_barc  = "";
public static String type_task  = "";

public static String id_tombol = "";

public boolean barcodenya = false;

private static final int CAMERA_REQUEST = 13731;
private static final int CAMERA_REQ = 13732;
public static final int REQUEST_CODE = 1;

这是代码，我想从config.php动态

public static int output_width=480;
public static int output_height=320;

$uploaded_image_width_height= "640x480";

这是config.php

public static int output_width=480;
public static int output_height=320;

$uploaded_image_width_height= "640x480";

---

我希望config.php中的dynamic、width和height打印出php中变量的值，然后在需要更新Java中变量时对该文件进行HTTP请求

public static int output_width=480;
public static int output_height=320;

$uploaded_image_width_height= "640x480";
