Running the LifeCycleTest activity
On startup,
onCreate()
is called, followed by
onResume()
. When we lock the screen,
onPause()
is called. When we unlock the screen,
onResume()
is called. When we press the home button,
onPause()
is called. Going back to the activity will call
onResume()
again. The same messages are,
of course, shown in LogCat, which you can observe in Eclipse in the LogCat view. Figure
4-5
shows what we wrote to LogCat while executing the preceding sequence of actions (plus
pressing the back button).
