-  Navigate to ``TaskTracker``, which initializes {+service-short+} and

-  {+service-short+} App reference, here:
+  Navigate to ``TaskTracker``. Android automatically runs the
+  ``onCreate()`` lifecycle method of this class when you launch
+  the Task Tracker app. This happens because ``TaskTracker`` is
+  configured as the global ``Application`` reference in
+  ``AndroidManifest.xml``. This allows us to run certain logic
+  once each time you run the app, such as:
+  
+  - initializing {+service-short+}
+  - defining the global ``App`` reference using the ``appId``
+    variable you just configured in your app-level
+    ``build.gradle`` file
+  - setting the {+service-short+} log level

+  You don't need to make any changes to this file right now,
+  but it is useful to know where to configure these global
+  settings in case you need to change the log level or debug
+  issues with your App connection.
