Frequent Orientation Change is giving Null Pointer Exception for Textview

Question

My Problem is, TextView is giving java.lang.NullPointerException if I do Orientation changes frequently. I pasted my code below. Am I missing something?

@Override
public void onSaveInstanceState(Bundle outState) {

    if (title.getText().toString() != null) {      //Getting Null Exception here
        Log.i("onSaveInstanceState", "  "+title.getText().toString());
        outState.putString("title", title.getText().toString());
    }
}

--

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
    view=inflater.inflate(R.layout.add, null);
    title =(TextView) view.findViewById(R.id.title);

    if (savedInstanceState.getString("title") != null) {
        Log.i("on create", " "+savedInstanceState.getString("title"));
        title.setText(savedInstanceState.getString("title"));
    }
}

Try this way

@Override
public void onSaveInstanceState(Bundle outState) {

    if (title.getText() != null) {      //Getting Null Exception here
        Log.i("onSaveInstanceState", "  "+title.getText().toString());
        outState.putString("title", title.getText().toString());
    }
}

You're comparing the result of evaluating something that's null, that way it will give you a NullPointerException.

UPDATE

Reffer to this SO Post where the accepted answer points out that you need to search again for the TextView widget in onSaveInstanceState method.
