    final static String TWITTER_STREAM_URL = "https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=";

    public TwitterAPI(String twitterAPIKey, String twitterApiSecret){

        this.twitterAPISecret = twitterApiSecret;

    ...

推荐答案

向类TwitterAPI添加默认构造函数.

Add a default constructor to your class TwitterAPI.

//Default constructor takes no arguments
public TwitterAPI() { 
}
