Android activity restart

Question

I am having a confusion in restarting an activity.. I have two function that works well for the same task. Please guide me which is best and why?

public void restart()   
    {  
        Intent intent = getIntent();  
        overridePendingTransition(0, 0);  
        intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);  
        finish();  
        overridePendingTransition(R.anim.fade,R.anim.fade);
        startActivity(intent);

    }

or

public void restart()   
    {         
        onCreate();  
    }

Thanks In advance?

you should have studied the activity lifecycle. – Kakey May 26 '11 at 05:58 — Kakey, May 26 '11 at 05:58

I think this is a cleaner way for your requirement.

    Intent intent = getIntent();
    overridePendingTransition(0, 0);
    intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
    finish();
    overridePendingTransition(0, 0);
    startActivity(intent);

+1. Thats what I thought, but unable to explain why its better than the other. – Mudassir May 26 '11 at 05:59
Thankss u..Can you please explain why not to use the second option – GouravJn May 26 '11 at 06:01
Basically when we save the state the `Activity` then we call `onCreate(Bundle)` in case of rotation ...Other wise just `finish()` and call the intent again. – Tanmay Mandal May 26 '11 at 06:09
ok Tanmay... can u also explain the problem/error may arise in case of 'second opion' please?? – GouravJn May 26 '11 at 06:14
@Gourav It will not end your current activity state as well as it will not remove the activity from the activity stack. – Tanmay Mandal May 26 '11 at 06:21

This has been posted before:

Intent intent = getIntent();
finish();
startActivity(intent);

Activities in the system are managed as an activity stack. When a new activity is started, it is placed on the top of the stack and becomes the running activity -- the previous activity always remains below it in the stack, and will not come to the foreground again until the new activity exits.

for more info see Activity

Thanks Sir for your response, but when I close the running activity it get killed normally without showing an extra-ordinary behaviour(in case of second option)... – GouravJn May 26 '11 at 06:17
