====== Using the system log ======

''Log.d(//tag//, //message//)'' lets you output anything you want to the console when you run the app in debug mode. You have to import ''android.util.Log'' to use ''Log.d''.

Example:<code java>
Log.d("MyMessages", "Hello, world.");
</code>

In Android Studio, when you run your app in debug mode (//Run > Debug 'app'// or the bug icon in the toolbar or Shift+F9) you should see a new pane on the bottom panel: **6: Android monitor**. Your messages will show up there---along with a bunch of others.

You can filter out everything except what you have tagged with your //tag// by selecting "Edit filter configuration" from dropdown at the far right of the **6: Android monitor** pane and adding your //tag// to the "Log Tag" field. You may have to uncheck the "Regex" box.
