Android.Resource.Attribute.ConfigChanges Field
Specify one or more configuration changes that the activity will handle itself.

Value: 16842783

Syntax

[Android.Runtime.Register("configChanges")]
public const int ConfigChanges

Remarks

Specify one or more configuration changes that the activity will handle itself. If not specified, the activity will be restarted if any of these configuration changes happen in the system. Otherwise, the activity will remain running and its Android.App.Activity.OnConfigurationChanged(Android.Content.Res.Configuration) method called with the new configuration.

Note that all of these configuration changes can impact the resource values seen by the application, so you will generally need to re-retrieve all resources (including view layouts, drawables, etc) to correctly handle any configuration change.

These values must be kept in sync with those in Android.Content.PM.ActivityInfo and include/utils/ResourceTypes.h.
