android - Android - リモート ログインは成功したが、ログイン状態が保持されない

Question

認証を含むリモートサーバーからデータを取得するAndroidアプリがあります。リモートサーバーは Yii を使用しています。私たちの iPhone バージョンは、リモート Web サービスを使用しており、まったく問題はありません。しかし、私たちの Android では: 1) ログインでき、サーバーは 200 を返します。2）しかし、次のページで別のAPIを呼び出してデータベースを照会しようとすると、ユーザーがログインしていないというエラーが返され続けます.

私が行ったこと: 1. バックエンドでユーザー セッションを確認します。はい、Android からログインすると、ユーザー セッションがアクティブに表示されます。2. Firefox の POSTER と同じ API 呼び出しを使用します。はい、データを取得できます。

何がうまくいかなかったのでしょうか？誰か助けてくれませんか？どうもありがとう！

これが私のログインコードです：

    EditText etUser, etPass;
    Button bLogin, btnCancel;

    //Create string variables that will have the input assigned to them
    String username, password;

    //Create a HTTPClient as the form container
    HttpClient httpclient;

    //Use HTTP POST method
    HttpPost httppost;

    //Create an array list for the input data to be sent
    ArrayList<NameValuePair> nameValuePairs;

    //Create a HTTP Response and HTTP Entity
    HttpResponse response;

更新しました

私はアナンドの解決策を試しました：IT's WORKING!!!

Common.java:

import ...

public class Common {
    public static CookieStore cookieStore = new BasicCookieStore();
}

ログインコード:

public class Login extends Activity implements OnClickListener {

static HttpContext localContext = new BasicHttpContext();

...

   protected Integer doInBackground(Void... params) {
        localContext.setAttribute(ClientContext.COOKIE_STORE, Common.cookieStore);
        //Create new default HTTPClient
        httpclient = new DefaultHttpClient();

        //Create new HTTP POST with URL to php file as parameter
        httppost = new HttpPost(... api ...); 

ログイン後の 2 回目の呼び出し (別のクラス):

public class GetMybookings extends ListActivity {

    static HttpContext localContext = new BasicHttpContext();
        ....
        protected ArrayList<jobs> doInBackground(String... urls) {
            try {
                HttpClient httpClient = new DefaultHttpClient();
                HttpGet httpGet = new HttpGet(... api ....);
                HttpResponse response = null;

                try {
                    localContext.setAttribute(ClientContext.COOKIE_STORE, Common.cookieStore);
                    response = httpClient.execute(httpGet, localContext);
