2,533 Pointsstuck on the message I should send
I do not know how to send or what to send as a message to the handler, I tried to send a twitterClient as an obj but it didn't work. Please help me
public class MainActivity extends Activity {
Button button;
TwitterClient twitterClient = new TwitterClient();
@Override
public void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.activity_main);
final TwitterThread twitterThread = new TwitterThread();
twitterThread.setName("TwitterThread");
twitterThread.start();
button = (Button) findViewById(R.id.update_button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v){
Message message = Message.obtain();
message.obj = twitterClient;
twitterThread.handler.sendMessage(message);
}
});
}
class TwitterHandler extends Handler{
@Override
public void handleMessage(Message msg){
twitterClient.update();
}
}
class TwitterThread extends Thread {
TwitterHandler handler = null;
@Override
public void run() {
Looper.prepare();
handler = new TwitterHandler();
Looper.loop();
}
}
}

Treehouse Guest TeacherHello Mohammed,
You're so close! The only issue in your code is inside the button onClick listener. You don't need to set message.obj. Remove that line and you should pass the challenge. It should be like the following.
public void onClick(View v){
Message message = Message.obtain();
twitterThread.handler.sendMessage(message);
}
I hope this helps.
