### loadFromApk
Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static ResourcesProvider loadFromApk (ParcelFileDescriptor fileDescriptor,
AssetsProvider assetsProvider)
```
Creates a ResourcesProvider from an APK (`.apk`) file descriptor.
The file descriptor is duplicated and the original may be closed by the application at any
time without affecting the ResourcesProvider.
The assets provider can override the loading of files within the APK and can provide
entirely new files that do not exist in the APK.
| Parameters ||
|---|---|
| `fileDescriptor` | `ParcelFileDescriptor`: the file descriptor of the APK to load. This value cannot be `null`.
|
| `assetsProvider` | `AssetsProvider`: the assets provider that overrides the loading of file-based resources. This value may be `null`.

### loadFromDirectory
Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static ResourcesProvider loadFromDirectory (String path,
AssetsProvider assetsProvider)
```
Creates a ResourcesProvider from a directory path.
File-based resources will be resolved within the directory as if the directory is an APK.
| Parameters ||
|---|---|
| `path` | `String`: the path of the directory to treat as an APK. This value cannot be `null`.
|
| `assetsProvider` | `AssetsProvider`: the assets provider that overrides the loading of file-based resources. This value may be `null`.
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/android/content/res/loader/ResourcesProvider` | This value cannot be `null`.
|
| Throws ||

### loadFromSplit
Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static ResourcesProvider loadFromSplit (Context context,
String splitName)
```
Read from a split installed alongside the application, which may not have been
loaded initially because the application requested isolated split loading.
| Parameters ||
|---|---|
| `context` | `Context`: a context of the package that contains the split. This value cannot be `null`.
|
| `splitName` | `String`: the name of the split to load. This value cannot be `null`.
|
| Returns ||

### loadFromTable
Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static ResourcesProvider loadFromTable (ParcelFileDescriptor fileDescriptor,
AssetsProvider assetsProvider)
```
Creates a ResourcesProvider from a resources table (`.arsc`) file descriptor.
The file descriptor is duplicated and the original may be closed by the application at any
time without affecting the ResourcesProvider.
The resources table format is not an archive format and therefore cannot asset files
within itself. The assets provider can instead provide files that are potentially referenced
by path in the resources table.
| Parameters ||
|---|---|
| `fileDescriptor` | `ParcelFileDescriptor`: the file descriptor of the resources table to load. This value cannot be `null`.
|
| `assetsProvider` | `AssetsProvider`: the assets provider that implements the loading of file-based resources. This value may be `null`.
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/android/content/res/loader/ResourcesProvider` | This value cannot be `null`.
|
| Throws ||
|---|---|
| `https://developer.android.com/reference/java/io/IOException` | |
**See also:**
- `https://developer.android.com/reference/android/os/ParcelFileDescriptor#open(java.io.File,%20int)`

### loadOverlay
Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static ResourcesProvider loadOverlay (OverlayInfo overlayInfo)
```
Creates a ResourcesProvider instance from the specified overlay information.
In order to enable the registered overlays, an application can create a `https://developer.android.com/reference/android/content/res/loader/ResourcesProvider` instance according to the specified `https://developer.android.com/reference/android/content/om/OverlayInfo` instance and put
them into a `https://developer.android.com/reference/android/content/res/loader/ResourcesLoader` instance. The application calls `https://developer.android.com/reference/android/content/res/Resources#addLoaders(android.content.res.loader.ResourcesLoader[])` to load the overlays.
| Parameters ||
|---|---|
| `overlayInfo` | `OverlayInfo`: is the information about the specified overlay. This value cannot be `null`.
|
| Returns ||
|---|---|
| `https://developer.android.com/reference/android/content/res/loader/ResourcesProvider` | the resources provider instance for the `overlayInfo` This value cannot be `null`.
|
| Throws ||
|---|---|
| `https://developer.android.com/reference/java/io/IOException` | when the files can't be loaded. |
