Android:configchanges Property

When you set the activity's android:configchanges, the screen will recall the various lifecycles

I actually test the discovery settings

android:configchanges= "Keyboardhidden|orientation" or not set
The OnCreate is also executed every time the screen toggles, and does not execute onconfigurationchanged
Set up
Android:configchanges= "Orientation|screensize"
OnCreate is not executed and onconfigurationchanged is executed.
Test code:

public class Mainactivity extends Activity {    TextView lbl;    @Override    protected void onCreate (Bundle savedinstancestate) {        super.oncreate (savedinstancestate);        Setcontentview (r.layout.activity_main);        LBL = (TextView) Findviewbyid (R.id.label);        LOG.D ("123", "onCreate");    }    @Override public    void onconfigurationchanged (Configuration newconfig) {        super.onconfigurationchanged ( Newconfig);        if (newconfig.orientation = = configuration.orientation_landscape) {            lbl.settext ("horizontal screen");        }        else{            Lbl.settext ("vertical screen");}}}    

<activity    android:name= ". Mainactivity "    android:label=" @string/app_name "    android:configchanges=" Orientation|screensize ">    <intent-filter>        <action android:name= "Android.intent.action.MAIN"/>        <category android: Name= "Android.intent.category.LAUNCHER"/>    </intent-filter></activity>
