Android中应该使用什么库和什么方法，从而获得类似于Java代码的搜索？

我在应用程序中实现搜索。我尝试实施第七个答案中提出的方案

我使用com_google_api_google_api_services_customsearch_v1_rev74_1_25_0.xml库

import com.google.api.client.googleapis.javanet.GoogleNetHttpTransport;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.services.customsearch.Customsearch;
import 
com.google.api.services.customsearch.CustomsearchRequestInitializer;
import com.google.api.services.customsearch.model.Result;
import com.google.api.services.customsearch.model.Search;

import java.io.IOException;
import java.security.GeneralSecurityException;

public class Main {
public static void main(String[] args) throws GeneralSecurityException, 
IOException {

    //  String searchQuery = "test"; //The query to search
    //  String cx = "MyCx"; //Your search engine

    String searchQuery = "test"; //The query to search
    String cx = "MyCx"; //Your search engine


    //Instance Customsearch
    Customsearch cs= null;
    try {
        cs = new Customsearch.Builder(GoogleNetHttpTransport.newTrustedTransport(), JacksonFactory.getDefaultInstance(), null)
                .setApplicationName("MYApp")
                .setGoogleClientRequestInitializer(new CustomsearchRequestInitializer("MyKey"))
                .build();
        System.out.println("cs= "+cs);
    } catch (GeneralSecurityException e) {
        System.out.println("GeneralSecurityException cs");
    } catch (IOException e) {
        System.out.println("IOException cs");

    } catch (Exception e) {
        System.out.println("Exception cs");
    }

    //Set search parameter
    Customsearch.Cse.List list = null;
    try {
        list = cs.cse().list(searchQuery).setCx(cx);
        System.out.println("list= "+list);
    } catch (IOException e) {
        System.out.println("IOException list");
    }


    //Execute search
    Search result= null;
    try {
        result = list.execute();
    } catch (IOException e) {
        System.out.println("IOException result");
    }

    if (result!=null) { if  (result.getItems()!=null){
        for (Result ri : result.getItems()) {
            //Get title, link, body etc. from search
            System.out.println(ri.getTitle() + ", " + ri.getLink());
        }

    }  else {  System.out.println(" resultgetItems()= null"); }
    }  else {  System.out.println(" result= null"); }
  }

}

此代码在Android Studio中不起作用。
