可以使用SharedPreferences或者SQLite来保存用户信息

private static HashMap
    
       CookieContiner=new HashMap
     
      () ;     /** 	 * 保存Cookie 	 * @param resp 	 */     public void SaveCookies(HttpResponse httpResponse)     {
      	Header[] headers = httpResponse.getHeaders("Set-Cookie");     	String headerstr=headers.toString();         if (headers == null)             return;         for(int i=0;i
      
       1?keyPair[1].trim():"";         		CookieContiner.put(key, value);         	}         }     }     /**      * 增加Cookie      * @param request      */     public void AddCookies(HttpPost request)     {
          StringBuilder sb = new StringBuilder();         Iterator iter = CookieContiner.entrySet().iterator();         while (iter.hasNext()) {
            Map.Entry entry = (Map.Entry) iter.next();           String key = entry.getKey().toString();           String val = entry.getValue().toString();           sb.append(key);           sb.append("=");           sb.append(val);           sb.append(";");         }         request.addHeader("cookie", sb.toString());     }
      
     
    

做了一个android网络应用，要求用自己实现的webview去访问web网站，并且在远程登录成功之后把cookie写入到手机，保留用作以后的自动登录。找了好多资料。发觉读取cookies倒还用的很普遍，可是通过程序写cookie却没有太多资料。

先来看一下如何读取cookie吧：

try

        {

          DefaultHttpClient httpclient = new DefaultHttpClient();

          HttpGet httpget = new HttpGet("");

          HttpResponse response = httpclient.execute(httpget);

          HttpEntity entity = response.getEntity();

          List<Cookie> cookies = httpclient.getCookieStore().getCookies();

          if (entity != null) {

              entity.consumeContent();

          }

       

          if (cookies.isEmpty()) {

            Log.i(TAG, "NONE");

         } else {

             for (int i = 0; i < cookies.size(); i++) {            

               Log.i(TAG,"- domain " + cookies.get(i).getDomain());

               Log.i(TAG,"- path " + cookies.get(i).getPath());

               Log.i(TAG,"- value " + cookies.get(i).getValue());

               Log.i(TAG,"- name " + cookies.get(i).getName());

               Log.i(TAG,"- port " + cookies.get(i).getPorts());

               Log.i(TAG,"- comment " + cookies.get(i).getComment());

               Log.i(TAG,"- commenturl" + cookies.get(i).getCommentURL());

               Log.i(TAG,"- all " + cookies.get(i).toString());

             }

         }

          httpclient.getConnectionManager().shutdown();

       

        }catch(Exception e){

          //Todo

        }finally{

        //Todo        

        }

通过分析com.android.browser的源码，发现android默认的browser增加cookie是在数据库中增加记录，和window不同，win是采用一个txt文本文件的形式来存储cookie。而android是将cookie存储在数据库中。具体的介绍在《android cookie存储位置》一文中有介绍。我们都知道，android每个应用程序的存储空间都是独立的。不管使用preference还是database存储，都会在每个/data/data/package name/下面进行存储（preference存储在/data/data/package name/shared_prefs/xxxx.xml）。前面也说到cookie是存在数据库中，那么如果采用非浏览器访问网络需要保留cookie的话我们就应该在database中建立cookies表，并且存入相应的cookies数据。仿照默认broswer的代码：

/**声明一些数据库操作的常量*/

  private static SQLiteDatabase mDatabase = null;

  private static final String DATABASE_FILE = "webview.db";

  private static final String COOKIES_NAME_COL = "name";

  private static final String COOKIES_VALUE_COL = "value";

  private static final String COOKIES_DOMAIN_COL = "domain";

  private static final String COOKIES_PATH_COL = "path";

  private static final String COOKIES_EXPIRES_COL = "expires";

  private static final String COOKIES_SECURE_COL = "secure";

mDatabase = LoginApiActivity.this.openOrCreateDatabase(DATABASE_FILE, 0, null);

//创建cookie数据库

    if (mDatabase != null) {

      // cookies

      mDatabase.execSQL("CREATE TABLE IF NOT EXISTS cookies "

              + " (_id INTEGER PRIMARY KEY, "

              + COOKIES_NAME_COL + " TEXT, " + COOKIES_VALUE_COL

              + " TEXT, " + COOKIES_DOMAIN_COL + " TEXT, "

              + COOKIES_PATH_COL + " TEXT, " + COOKIES_EXPIRES_COL

              + " INTEGER, " + COOKIES_SECURE_COL + " INTEGER" + ");");

      mDatabase.execSQL("CREATE INDEX IF NOT EXISTS cookiesIndex ON "

              + "cookies" + " (path)");

    }

  }

 

/*写cookie*/

  public void addCookie(Cookie cookie) {

    if (cookie.getDomain() == null || cookie.getPath() == null || cookie.getName() == null

            || mDatabase == null) {

        return;

    }

    String mCookieLock = "asd";

    synchronized (mCookieLock) {

        ContentValues cookieVal = new ContentValues();

        cookieVal.put(COOKIES_DOMAIN_COL, cookie.getDomain());

        cookieVal.put(COOKIES_PATH_COL, cookie.getPath());

        cookieVal.put(COOKIES_NAME_COL, cookie.getName());

        cookieVal.put(COOKIES_VALUE_COL, cookie.getValue());

 

        mDatabase.insert("cookies", null, cookieVal);

     

    }

}
