9,066 PointsLog.d(tag, msg)?? Why am I getting errors?
in my own android studio it removes the tag id automatically when I used TAG :
Log.d( TAG, "We're logging from the onCreate() method");
but here I tried: Log.d( tag: TAG, "We're logging from the onCreate() method");
as well as:
Log.d( TAG, "We're logging from the onCreate() method");
and I kept getting errors? Help?
package com.teamtreehouse;
public class TreehouseActivity extends Activity {
public static final String TAG = "TreehouseActivity";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_treehouse);
Log.d(tag: TAG, msg: "Activity created!");
}
}

Notice how they are highlighted and in a different font in AS. They are also not editable. It's additional guidance from AS telling you what arguments the method expects. You do not type them in yourself and don't appear in your code outside of AS.

9,066 PointsThanks Seth!! I know that, but I don't know how to write it for the challenge as they don't automatically pop up when I type Log.d ?

Just the two values separated by a comma.
