Difference between onCreate and onStart

Question

Possible Duplicate    Android Activity Life Cycle - difference between onPause   and OnStop         I was wondering - what is the difference between onCreate   and onStart   methods   I think that onStart   is a redundant method  onCreate   will ALWAYS be called  At least in my last two projects    Can any one explain the difference

onCreate   method gets called when activity gets created  and its called only once in whole Activity life cycle  where as onStart   is called when activity is stopped    I mean it has gone to background and its onStop   method is called by the os  onStart   may be called multiple times in Activity life cycle More details here

Take a look on life cycle of Activity   Where      onCreate        Called when the activity is first created  This is where you should do all of your normal static set up  create views  bind data to lists  etc  This method also provides you with a Bundle containing the activity s previously frozen state  if there was one  Always followed by onStart        onStart        Called when the activity is becoming visible to the user  Followed by onResume   if the activity comes to the foreground  or onStop   if it becomes hidden   And you can write your simple class to take a look when these methods call  public class TestActivity extends Activity           Called when the activity is first created          private final static String TAG    TestActivity         Override     public void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout main           Log i TAG   On Create                        non-Javadoc         see android app Activity onDestroy               Override     protected void onDestroy              super onDestroy            Log i TAG   On Destroy                        non-Javadoc         see android app Activity onPause               Override     protected void onPause              super onPause            Log i TAG   On Pause                         non-Javadoc         see android app Activity onRestart               Override     protected void onRestart             super onRestart            Log i TAG   On Restart                         non-Javadoc         see android app Activity onResume               Override     protected void onResume             super onResume            Log i TAG   On Resume                         non-Javadoc         see android app Activity onStart               Override     protected void onStart             super onStart            Log i TAG   On Start                        non-Javadoc         see android app Activity onStop               Override     protected void onStop             super onStop            Log i TAG   On Stop                    Hope this will clear your confusion   And take a look here for details   Lifecycle Methods in Details is a very good example and demo application  which is a very good article to understand the life cycle
