Onstop method is called when Orientation changes

Question

When I change the orientation of the Android application, it calls onStop method and then onCreate. How to avoid caling onStop and onCreate when orientation changes?

Answer 1

It have been long time since this question have been active, but I sill need to answer this. I had same issue and found answer.

In manifest you should add android:configChanges=orientation|screenLayout|layoutDirection|screenSize in your activity which should not call default actions on orientation change.

...
<activity android:name=".Activity"
  android:screenOrientation="portrait"
  android:configChanges="orientation|screenLayout|layoutDirection|screenSize" 
...

And in your activity:

@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
    // This overrides default action
}

This is the default behavior: the activity is recreated when orientation changes. But you can decide to ignore this event. You can find details here : How to make an application ignore screen orientation change?
