我正在开发一个小型应用程序，并且需要进行身份验证。我正在尝试通过 php 连接到 MYsql db 来进行开发。

添加 uname/pw --> 日志记录 --> 发送到 php --> 检查 db --> ok 发送回 android --> 已验证。/ 错误发送回重新登录。

到目前为止，我已经发展了，我认为应该是这样，但我不确定，因为我对绳索真的很陌生。
请善意地帮助我进行接线。谢谢你。

public class Loging extends Activity{

    TextView txt;
    EditText uname,pwd;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        setContentView(R.layout.loging);
        Button b = (Button)findViewById(R.id.log);
        uname = (EditText)findViewById(R.id.uname);
        pwd = (EditText)findViewById(R.id.pwd);

        b.setOnClickListener(new View.OnClickListener() {

            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

                    nameValuePairs.add(new BasicNameValuePair("name", uname.getText().toString()));
                    nameValuePairs.add(new BasicNameValuePair("Pass", pwd.getText().toString()));

                    try 
                    {
                     HttpClient httpclient = new DefaultHttpClient();
                     HttpPost httppost = new HttpPost("http://www.helloworld.com/report.php");
                     httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                     HttpResponse response = httpclient.execute(httppost);
                     HttpEntity entity = response.getEntity();
                     InputStream is = entity.getContent();
                    }
                    catch(Exception e)
                    {
                            Log.e("log_tag","Error in http connection"+e.toString());
