Question

我使用下面的代码将Jsondata发送到测试服务器，但我没有收到服务器的响应。我越来越异常了。解决这个问题的任何方法？如果我使用相同的代码将字符串发送到测试服务器它可以工作，但问题是Jsondata和Json数组。

public class MainActivity extends Activity 
{
AlertDialog alertDialog;
public EditText edit_text_Register_Username;
public EditText edit_text_password;
//SqlHandler sqlHandler;

String username,password;
String user,pass;

String result;
String fd_id;
String fd_name;
int value;

String asyn_response;
String status,contactid;

private static int RESULT_LOAD_IMAGE = 1;
ImageView mContent;
Bitmap mBitmap;

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ImageView upload = (ImageView) findViewById(R.id.imageView1);
     upload.setOnClickListener(new View.OnClickListener()
