copied!<p>Your <code>onCreate</code> method is called whenever the Android OS has to "create" your Activity.</p> <p>This will happen on the initial load of your Activity, and also whenever the OS has destroyed your activity voluntarily or if you call the activity's <code>finish()</code> method.</p> <p>The <code>onCreate</code> method is followed by another Activity method called <code>onStart</code>.</p> <p>This will be called when the Activity is now visible to the user.</p> <p>Regarding the <code>onLocationChanged</code> and <code>onTouchEvent</code> implementations, these two types of methods are executed by a listener that is set to the object.</p> <p>For example, <code>onLocationChanged</code> will execute every time your map listener has determined the location has changed.</p> <p>The <code>onTouchEvent</code> will execute any time your view has received a touch event from the user.</p> <p>Your <code>onPause</code> and <code>onResume</code> methods are part of the Activity class, these methods are similar to <code>onCreate</code>, although they are called at different times.</p> <p>Specifically, <code>onPause</code> is called whenever your Activity is not the front, focused view.</p> <p>The <code>onResume</code> method is the opposite of <code>onPause</code> - it will be called when your Activity's view is now the focused view on the screen.</p> <p><a href="http://developer.android.com/training/basics/activity-lifecycle/pausing.html" rel="nofollow">http://developer.android.com/training/basics/activity-lifecycle/pausing.html</a></p>
