私は小さなアプリケーションを開発しており、そのためには認証が必要です。PHP経由でMYsql dbに接続して開発しようとしています。

uname/pw を追加 --> ロギング --> php に送信 --> データベースをチェック --> OK で Android に送信 --> 認証済み。/ エラーは再ロギングに送り返されます。

私はこれまで開発してきましたが、これがどうあるべきかだと思いますが、私はコーディングに本当に慣れていないのでわかりません.
コーディングのお手伝いをお願いします。ありがとうございました。

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();
