Question

In Activity we have method

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    //...
}

My questions is:

1) If I didn’t override onSaveInstaceState, can savedInstanceState be not null?

2) If it can, is there a way to check existance of some savedInstanceState field better than

if(savedInstanceState.getString("SomeField")!=null){...}

3) How to handle onSaveInstanceState method in debugger? I testing my app on real device, that have a lot of memory (Asus TF101), so it’s a problem to “overflow” it each time.

Answer 1

1. No, it can’t. See http://developer.android.com/reference/android/app/Activity.html#onCreate(android.os.Bundle)
2. Use Bundle.containsKey
3. To “overflow”? What is the reason to do this?
