私はphpサーバーとアンドロイドと通信しようとしています

ここに私のJAVAファイルとphpがあります

// gson ライブラリを使用してデータを Json に変換します。→大丈夫です！

   String str = new TOJSON().tojson("testName", "TestPW", "testEmail", 77);

   USERDATA userdata = gson.fromJson(new HTTPCONNECTION().httpPost("http://testsever.com/test.php", str).toString(), USERDATA.class);

   textView textView = (TextView)findViewById(R.id.textView1);
   textView.setText(userdata.getName());

// PHP サーバーに接続する

public class HTTPCONNECTION {


    public String httpPost(String url, String str){
        HttpClient client = new DefaultHttpClient();
        HttpConnectionParams.setConnectionTimeout(client.getParams(), 30000);
        HttpResponse response;


        try {
            HttpPost httppost = new HttpPost(url);
            StringEntity entity = new StringEntity(str, "UTF-8");
            entity.setContentType("application/json");
            httppost.setEntity(entity);

            HttpResponse httpResponse = client.execute(httppost); 
            HttpEntity httpEntity = httpResponse.getEntity();
            Log.v("OWL", EntityUtils.toString(httpEntity));

            return EntityUtils.toString(httpEntity);
        }

        catch (ClientProtocolException e) {
            e.printStackTrace();
            return null;
        } 
        catch (IOException e) {
            e.printStackTrace();
            return null;
        }
}

およびphpファイルはjsonデータを取得し、jsonデータをテストに送信します

$value = json_decode(stripslashes($_POST), true);
echo (json_encode($value));

私の場合、サイドPHPで使用します

 $_POST = json_decode(file_get_contents("php://input"));

そしてAndroid側では

StringEntity se = new StringEntity(jsonObject.toString(),
                    HTTP.UTF_8);
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE,
                    "application/json"));
request.setEntity(se);

Android からサーバーに POST JSON データを送信する関数の完全なソース
