Package com.castlabs.android.player

## Class DrmLicenseLoader

- java.lang.Object
- - com.castlabs.android.player.DrmLicenseLoader

-     public class DrmLicenseLoader
      extends Object

  Use the `DrmLicenseLoader.Builder` to create instances of the license loader. The loader works asynchronously and you need to provide a callback implementation to be informed about potential error and the successful license deliveries.

  Please note that you need to specify a unique ID for the DRM configuration `DrmConfiguration.offlineId` and configure the local key storage accordingly (see `PlayerSDK.DEFAULT_KEY_STORE`).
  Since:
    3.0.2

    - #### fetchLicense

          public static boolean fetchLicense​(@NonNull
                                             Bundle playbackBundle,
                                             @NonNull
                                             KeyStore keyStore)

      Fetches the license and store it in the key store
      Parameters:
        `playbackBundle` - The playback bundle
        `keyStore` - The key store to use
      Returns:
        `true` if the fetch was successful and otherwise `false`

    - #### load

          public void load()

      Triggers an asynchronous license loading. The license loading happens on a dedicated thread in the background. The callback provided will be called to inform about errors or a successful license delivery.
      Throws:
        `NullPointerException` - if mandatory data are not specified

    - #### remove

          public void remove()

      Triggers an asynchronous license removal. The license loading happens on a dedicated thread in the background. The callback provided will be called to inform about errors or a successful license removal.

      Some DRM vendors, such as Widevine, require a request to be performed against the license delivery server. This is why Internet connection might be required.

      On license removal success, the corresponding key in the `PlayerSDK.DEFAULT_KEY_STORE` will also be removed.
