Android - ActionBar not resizing with onConfigurationChanged ( AppCompat )

Question

In my application manifest I\'ve add android:configChanges to prevent activity reload/restart on rotate

Answer 1

By setting android:configChanges="orientation|keyboardHidden|screenSize"

You declare that you will handle these config changes by yourself. In normal cases, you should not set that, and let Android recreate your Activity.

Edit:

If you want to keep the line android:configChanges, you have to override onConfigChanged() and change everything needed by yourself, e.g. the size of the ActionBar/ToolBar.
