我正在尝试Twitter4j使用搜索测试显示一些推文。目前，它不应该在屏幕上打印任何东西，只是system.out.printIn为了我的日食。但它强制关闭。

这是我的mainActivity：

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ConfigurationBuilder cb = new ConfigurationBuilder();
        cb.setDebugEnabled(true)
          .setOAuthConsumerKey("xxxxxxxxxxxxxxxxxxxxx")
          .setOAuthConsumerSecret("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
          .setOAuthAccessToken("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
          .setOAuthAccessTokenSecret("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
        TwitterFactory tf = new TwitterFactory(cb.build());
        Twitter twitter = tf.getInstance();

        // The factory instance is re-useable and thread safe.
        twitter = TwitterFactory.getSingleton();
        Query query = new Query("source:twitter4j yusukey");
        QueryResult result = null;
        try {
            result = twitter.search(query);
        } catch (TwitterException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        for (Status status : result.getTweets()) {
            System.out.println("@" + status.getUser().getScreenName() + ":" + status.getText());
        }
    }
}

我也用过twitter4j.properties

debug=true
oauth.consumerKey=xxxxxxxxx
oauth.consumerSecret=bxxxxxxxxxxx
oauth.accessToken=xxxxxxxxxxx
oauth.accessTokenSecret=xxxxxxx

问题是，一旦我打开应用程序，它就会关闭。logcat: _
