Application Tidy Up

Step 1

• Created TrackerActivity which extends AppCompatActivity and will be now good for other activities
• Move Tracker to its own class and implement the Lifecycle Observer interface

    @OnLifecycleEvent(Lifecycle.Event.ON_DESTROY)
    public void trackOnDestroy() {
        Log.d(TAG, "trackOnDestroy called");
        ((AppCompatActivity) con).getLifecycle().removeObserver(this);
        // mQueue.add(generateTrackingStringRequest("destroy"));
    }
