如何使用Twitter Fabric Android获取关注者列表？

实际上，Fabric使用改造来进行REST
Api调用，如Fabric文档中所述，要获取关注者的ID，我们需要将user_id作为参数传递并检索响应列表。

MyTwitterApiClient.java

import com.twitter.sdk.android.core.Callback;import com.twitter.sdk.android.core.TwitterApiClient;import com.twitter.sdk.android.core.TwitterSession;import retrofit.client.Response;import retrofit.http.GET;import retrofit.http.Query;    public class MyTwitterApiClient extends TwitterApiClient {        public MyTwitterApiClient(TwitterSession session) { super(session);        }                public CustomService getCustomService() { return getService(CustomService.class);        }    }    // example users/show service endpoint    interface CustomService {        @GET("/1.1/followers/ids.json")        void list(@Query("user_id") long id, Callback<Response> cb);    }

现在，在MainActivity中，我们将对用户进行身份验证，然后通过获取会话，将检索与该用户ID对应的所有关注者的列表。

MainActivity.java

public class MainActivity extends AppCompatActivity {    // Note: Your consumer key and secret should be obfuscated in your source pre before shipping.    private static final String TWITTER_KEY = "YOUR_TWITTER_KEY";    private static final String TWITTER_SECRET = "YOUR_TWITTER_SECRET";    TwitterLoginButton loginButton;    SharedPreferences shared;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);        Fabric.with(this, new Twitter(authConfig), new Crashlytics());        setContentView(R.layout.activity_main);        shared = getSharedPreferences("demotwitter", Context.MODE_PRIVATE);        loginButton = (TwitterLoginButton) findViewById(R.id.login_button);        loginButton.setCallback(new Callback<TwitterSession>() {@Overridepublic void success(Result<TwitterSession> result) {    // Do something with result, which provides a TwitterSession for making API calls     TwitterSession session = Twitter.getSessionManager()  .getActiveSession();     TwitterAuthToken authToken = session.getAuthToken();     String token = authToken.token;     String secret = authToken.secret;//Here we get all the details of user's twitter account     System.out.println(result.data.getUserName()  + result.data.getUserId());     Twitter.getApiClient(session).getAccountService()  .verifyCredentials(true, false, new Callback<User>() {      @Override      public void success(Result<User> userResult) {          User user = userResult.data;//Here we get image url which can be used to set as image wherever required.
