Question

When connected to the server i get the Cookies and store them in a List.

While making connections later i add these cookies to the DefaultHttpClient.

The problem is, when the Application is in background for sometime, all the class data is being lost including the DefaultHttpClient.

Hence i am losing the cookie.

Is there a way to keep the DefaultHttpClient alive forever?

or any better way to store and use cookies?

Thank You

Get it from the cookie, then save it in the shared prefferences when the app is killed (e.g. onStop method). Then reload it on onCreate(). Something similar to this:

public class Calc extends Activity {
   public static final String PREFS_NAME = "MyPrefsFile";

   @Override
   protected void onCreate(Bundle state){
      super.onCreate(state);
      . . .

      // Restore preferences
      SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
      String silent = settings.getString("cookie", null);
      if(cookie == null) {
          // first time, get cookie again and save it
      } else {
          // set cookie manually for HTTPClient
      }
   }

   @Override
   protected void onStop(){
      super.onStop();

     // We need an Editor object to make preference changes.
     // All objects are from android.context.Context
     SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
     SharedPreferences.Editor editor = settings.edit();
     editor.putString("cookie", theCookie);

     // Commit the edits!
     editor.commit();
   }
}

(I have omited the code for getting and setting the cookie, I assume that’s not a problem)
