I add a new code, I break the old one, what is it?

Question

Android

I am writing code to save variables when changing screen orientation.

@Override
    public void onSaveInstanceState(Bundle savedInstanceState) {
        super.onSaveInstanceState(savedInstanceState);
        Log.i(TAG, "onSaveInstanceState");
        savedInstanceState.putInt(KEY_INDEX, mCurrentIndex);
        savedInstanceState.putBooleanArray(KEY_INDEX, array);  
    }

   if (savedInstanceState != null) {
            mCurrentIndex = savedInstanceState.getInt(KEY_INDEX, 0);
            array = savedInstanceState.getBooleanArray(KEY_INDEX);
        }

Only one of these variables is saved, how can both variables be saved?

Answer 1

Keys must be different for different variables.
And you have one key - KEY_INDEX.
