I ran this code:

public static void Get() {

    MarketSession session = new MarketSession();
    session.login("[My Gamil]","[My Password]");
    session.getContext().setAndroidId("[My Gamil]");

    String query = "maps";
    AppsRequest appsRequest = AppsRequest.newBuilder()
                                    .setQuery(query)
                                    .setStartIndex(0).setEntriesCount(10)
                                    .setWithExtendedInfo(true)
                                    .build();

    session.append(appsRequest, new Callback<AppsResponse>() {
             @Override
             public void onResult(ResponseContext context, AppsResponse response) {
                      // Your code here
                      System.out.println(response.getApp(0).getCreator());
                      // see AppsResponse class definition for more infos
             }
    });
    session.flush();
}

and got this exception:
