Cant see where the error is coming from

Challenge Task 1 of 1

We've been seeing a lot of "Application Not Responding" errors with our custom Twitter app. Could you fix this by moving the 'twitterClient.update()' call to a separate Thread named 'TwitterThread'? Bummer! There is a compiler error. Please click on preview to view your syntax errors! Preview Get Help Reset Code Recheck work MainActivity.java

Ask a Question

MainActivity.java 
public class MainActivity extends Activity {
    TwitterClient twitterClient = new TwitterClient();

    @Override
    public void onCreate(Bundle savedInstanceState) {
      setContentView(R.layout.activity_main);

 TwitterThread twitterThread = new TwitterThread();
      twitterThread.setName("TwitterThread");
      twitterThread.start();
    }

    public class TwitterThread extends Thread {
      @Override
      public void run() {
        twitterClient.update();
      } 
    }
}

You need to create your run method inside a runnable. Then you need assign that runnable to a new thread, then set the name and finally start the thread.

      Runnable runnable = new Runnable() {
        @Override
        public void run() {
          twitterClient.update();
        }
      };

      Thread thread = new Thread(runnable);
      thread.setName("TwitterThread");
      thread.start();

Hope this help.

it didn't work for me I keep getting errors

./MainActivity.java:22: error: expected thread.setName("TwitterThread"); ^ ./MainActivity.java:22: error: illegal start of type thread.setName("TwitterThread"); ^ ./MainActivity.java:23: error: expected thread.start(); ^ ./MainActivity.java:22: error: package thread does not exist thread.setName("TwitterThread"); ^ ./MainActivity.java:23: error: package thread does not exist thread.start(); ^ 5 errors

public class MainActivity extends Activity { TwitterClient twitterClient = new TwitterClient();

@Override
public void onCreate(Bundle savedInstanceState) {
  setContentView(R.layout.activity_main);

TwitterThread twitterThread = new TwitterThread(); twitterThread.setName("TwitterThread"); twitterThread.start(); }

public class TwitterThread extends Thread {
  Runnable runnable = new Runnable() {
    @Override
    public void run() {
      twitterClient.update();
    }
  };

  Thread thread = new Thread(runnable);
  thread.setName("TwitterThread");
  thread.start();
}

}
