Remarks

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

The system will take ownership of the file descriptor returned from this method, so ParcelFileDescriptor#dup() dup the file descriptor before returning if the system should not own it.

There are two situations in which this method will be called: <ul> <li>AssetManager is queried for an InputStream of an asset using APIs like AssetManager#open and AssetManager#openXmlResourceParser. <li>AssetManager is resolving the value of a file-based resource provided by the ResourcesProvider this instance is associated with. </ul>

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.
