public class DirectoryAssetsProvider
extends Object implements AssetsProvider

java.lang.Object
↳	android.content.res.loader.DirectoryAssetsProvider

A AssetsProvider that searches a directory for assets. Assumes that resource paths are resolvable child paths of the root directory passed in.

Summary

Public constructors
`DirectoryAssetsProvider(File directory)` Creates a DirectoryAssetsProvider with given root directory.

Public methods
`File`	`findFile(String path)` Finds the file relative to the root directory.
`File`	`getDirectory()`
`InputStream`	`loadAsset(String path, int accessMode)` Callback that allows the value of a file-based resources or asset to be specified or overridden.
`ParcelFileDescriptor`	`loadAssetParcelFd(String path)` `ParcelFileDescriptor` variant of `loadAsset(java.lang.String, int)`.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public constructors

DirectoryAssetsProvider

Added in Android R

public DirectoryAssetsProvider (File directory)

Creates a DirectoryAssetsProvider with given root directory.

Parameters
`directory`	`File`: the root directory to resolve files from This value must never be `null`.

Public methods

findFile

Added in Android R

public File findFile (String path)

Finds the file relative to the root directory.

Parameters
`path`	`String`: the relative path of the file This value must never be `null`.

Returns
`File`	This value may be `null`.

getDirectory

Added in Android R

public File getDirectory ()

Returns
`File`	This value will never be `null`.

loadAsset

Added in Android R

public InputStream loadAsset (String path, 
                int accessMode)

Callback that allows the value of a file-based resources or asset to be specified or overridden.

There are two situations in which this method will be called:

AssetManager is queried for an InputStream of an asset using APIs like AssetManager#open and AssetManager#openXmlResourceParser.
AssetManager is resolving the value of a file-based resource provided by the ResourcesProvider this instance is associated with.

If the value retrieved from this callback is null, AssetManager will attempt to find the file-based resource or asset within the APK provided by the ResourcesProvider this instance is associated with.

Parameters
`path`	`String`: This value must never be `null`.
`accessMode`	`int`: the `AssetManager` access mode

Returns
`InputStream`	This value may be `null`.

Throws
`IOException`

loadAssetParcelFd

Added in Android R

public ParcelFileDescriptor loadAssetParcelFd (String path)

ParcelFileDescriptor variant of loadAsset(java.lang.String, int).

Parameters
`path`	`String`: This value must never be `null`.

Returns
`ParcelFileDescriptor`	This value may be `null`.

Throws
`IOException`
