My log's arent working

Hey there! I followed the steps of the video tutorial but my logs aren't being displayed in the logcat. There's a line just above the logcat that indicates that my emulator is disconnected and I'm guessing that thats the reason behind the problem, however my emulator works normal when I run the program.

You might need to close and restart the emulator to reattach it. Otherwise there will be no way to see the logs.

Log.d( TAG, "Activity created!"); don't include tag: or msg:, they appear after you press enter but you are not supposed to type them.

I noticed the same issue. It wasn't working with me either, and that's probably because we both tried to import the class Log, right? In case you did so, just remove the import and then it should work - although it doesn't make sense, I know. Usually, they remind you to import the class here at Treehouse, but because they didn't this time, and the exercise wasn't working every time I pressed on 'check work', I noticed that there's something wrong with this exercise.

package com.teamtreehouse;

// comment this line and it should be fine
//import android.util.Log;

public class TreehouseActivity extends Activity {

  public static final String TAG = TreehouseActivity.class.getSimpleName();

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

    Log.d(TAG, "Activity created!");
  }
}

If it's still not working just refresh the page and retry and it should eventually work ?.

One last thing: I hope you're not typing msg: passing an argument. I mean like this;

Log.d (TAG, msg:"Activity created!");

Cause this just IntelliJ's hint on what parameter should be passed here and in which order, but you certainly shouldn't be typing the name of the parameter.

// Right!
Log.d (TAG, "Activity created!");
