## Constants
### ID_NULL
Added in[1.3.0](https://developer.android.com/jetpack/androidx/releases/core#1.3.0)
```
const val ID_NULL = 0: @AnyRes Int
```
The`null`resource ID. This denotes an invalid resource ID that is returned by the system when a resource is not found or the value is set to`@null`in XML.
## Public functions
### clearCachesForTheme
Added in[1.8.0](https://developer.android.com/jetpack/androidx/releases/core#1.8.0)
```
java-static fun clearCachesForTheme(theme: Resources.Theme): Unit
```
Clears cached values associated with the specified[Theme](https://developer.android.com/reference/android/content/res/Resources.Theme.html).
This method allows developers to work around issues related to stale cached resources that may occur on API level 32 and below following a call to[applyStyle](https://developer.android.com/reference/android/content/res/Resources.Theme.html#applyStyle(int, boolean)). If you are not explicitly calling`
applyStyle`in your code, you probably do not need to call this method.
Starting in Android T, the Theme class correctly implements[hashCode](https://developer.android.com/reference/android/content/res/Resources.Theme.html#hashCode())and cached values will be appropriately cleared when the contents of a Theme object change.
| Parameters |
|--------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------|
| `theme: `[Resources.Theme](https://developer.android.com/reference/android/content/res/Resources.Theme.html) | the theme for which associated values should be cleared from the resource cache |
### getCachedFont
Added in[1.5.0](https://developer.android.com/jetpack/androidx/releases/core#1.5.0)
```
java-static fun getCachedFont(context: Context, id: @FontRes Int): Typeface?
```
Returns a cached font Typeface associated with a particular resource ID.
This method returns non-null Typeface if the requested font is already fetched. Otherwise immediately returns null without requesting to font provider.
Prior to API level 23, font resources with more than one font in a family will only load the font closest to a regular weight typeface.

|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `context: `[Context](https://developer.android.com/reference/android/content/Context.html) | A context to retrieve the Resources from. |
| `id: @`[FontRes](https://developer.android.com/reference/kotlin/androidx/annotation/FontRes)` `[Int](https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-int/index.html) | The desired resource identifier of a[Typeface](https://developer.android.com/reference/android/graphics/Typeface.html), as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier. |
| Returns |
|---------------------------------------------------------------------------------------|-------------------------|
| [Typeface](https://developer.android.com/reference/android/graphics/Typeface.html)`?` | A font Typeface object. |
| Throws |
|-------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------|

```
java-static fun getColor(res: Resources, id: @ColorRes Int, theme: Resources.Theme?): @ColorInt Int
```
Returns a themed color integer associated with a particular resource ID. If the resource holds a complex[ColorStateList](https://developer.android.com/reference/android/content/res/ColorStateList.html), then the default color from the set is returned.
Prior to API level 23, the theme will not be applied and this method calls through to[getColor](https://developer.android.com/reference/android/content/res/Resources.html#getColor(int)).
| Parameters |
|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------|
