java.lang.Object

net.idrnd.facesdk.android.AssetsExtractor

public class AssetsExtractor
extends java.lang.Object

Allows Java IO access to AAR-packaged resources.

Call extractAssets() to unpack resources to local storage. Android uses special assets URI and storage inside the generated AARs and APKs Assets are logically located inside src/xxx/assets folder in any Android project. These assets are then compressed and packaged inside the resulting AAR/APK. They can't be accessed through standard Java IO methods, AssetManager is the only way to access them.
