First connection to userEndpoint takes long time in Android with appEngine

In my android app, after sometime (hour or so.. not something determined) the connection and response to Google-AppEngine takes very long, something like 10 seconds or more.

After the first connection all other enpoint requests are done pretty quickly and this is why I believe this is SW issue and not internet connection issue.

Should I establish a 'dummy' connection as the app is loaded ?

Here is a sample code of an AsyncTask which tried to get User entity from AppEngine endpoint :

private class getUser extends AsyncTask<Void, Void, Boolean> {

    long mTaskUserId = Constants.USER_ID_NO_ID_INFDICATOR;
    String mIdInPlatform = Constants.USER_ID_NO_ID_INFDICATOR.toString();
    Long mServerScore;
    Context mContext;
    String mUserName;

    getUser(String idInPlatform, String userName, Context c) {
        mIdInPlatform = idInPlatform;
        mUserName = userName;
        mContext = c;
    }

    @Override
    protected Boolean doInBackground(Void... params) {

        Userendpoint.Builder builder = new Userendpoint.Builder(
                AndroidHttp.newCompatibleTransport(), new JacksonFactory(), null);
        builder = CloudEndpointUtils.updateBuilder(builder);
        Userendpoint endpoint = builder.build();

        try {
            User user = endpoint.getUser().execute();
        } catch (IOException e) {
            Log.e(TAG, "Error getting user details from server ", e);
            return false;
        }
        this.mUserName = user.getUserName();
        this.mServerScore = user.getScore();
        this.mTaskUserId = user.getId();

        return true;
    }

    @Override
    protected void onPostExecute(Boolean result) {
        if (result) {
            setUserFacebookIdInPreferences(mIdInPlatform, mContext);
            setUserIdInPreferences(this.mTaskUserId, mContext);
            setScoreInPreferences(this.mServerScore, mContext);
            setUserNameInPreferences(this.mUserName, mContext);
        } else {
            Toast.makeText(mContext, R.string.string_login_failed, Toast.LENGTH_SHORT).show();
        }
        // Restart login activity.
        moveToLoginActivity(result);
        super.onPostExecute(result);
    }
}
