Question

I read many posts about this problem like [this link][1] and one solution is add orientation configChanges to manifest and handle onConfigurationChanged event in order to prevent onCreate activity to be called again when rotation. I did it and event is triggered properly, however, after this execution, onCreate method is also executed! why? what I am missing? Thank you

manifest,

<activity 
            android:name="webPush"
            android:configChanges="keyboardHidden|orientation"/>

activity,

@Override
    public void onConfigurationChanged(Configuration newConfig) {
      super.onConfigurationChanged(newConfig);
      setContentView(R.layout.vistaaib);
    }

@Override
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.vistaaib);
...

See http://web.archive.org/web/20120130201824/https://developer.android.com/guide/topics/resources/runtime-changes.html —

<activity android:name=".MyActivity"
          android:configChanges="orientation|keyboardHidden"
          android:label="@string/app_name">

Beginning with Android 3.2 (API level 13), the will "screen size" also
changes when the device switches between portrait and landscape
orientation. Thus, if you want to prevent runtime restarts due to
orientation change when developing for API level 13 or higher you must use:

android:configChanges="orientation|screenSize"
