| This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX.

**Note:** On platform versions prior to[API 23](https://developer.android.com/reference/android/os/Build.VERSION_CODES.html#M), delegate methods on views in the`android.widget.*`package are called*before* host methods. This prevents certain properties such as class name from being modified by overriding[onInitializeAccessibilityNodeInfo(View, AccessibilityNodeInfoCompat)](https://developer.android.com/reference/android/support/v4/view/AccessibilityDelegateCompat#onInitializeAccessibilityNodeInfo(android.view.View, android.support.v4.view.accessibility.AccessibilityNodeInfoCompat)), as any changes will be overwritten by the host class.
Starting in[API 23](https://developer.android.com/reference/android/os/Build.VERSION_CODES.html#M), delegate methods are called*after*host methods, which all properties to be modified without being overwritten by the host class.
