This guide outlines the changes to Nutrient Android SDK 2024.6.

## API changes

- The [`PdfFragment`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui/-pdf-fragment/save.html) `save` method has changed to _not_ show the saving spinner, as we’ve had very rare file corruption issues when running this operation on a background thread. `save` now blocks until saving has completed.
  We added [`saveAsync`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui/-pdf-fragment/save-async.html), which does the same thing as the previous `save` method.

- [`Annotation`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.annotations/-annotation/) has a new [`getFillAlpha`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.annotations/-annotation/get-fill-alpha.html) method, which retrieves a separate alpha value if an annotation has a different fill alpha than its `alpha`.
  This value can only be set with an API for now. If you need to be able to adjust it via the user interface (UI), contact our [Support team](https://support.nutrient.io/hc/en-us/requests/new).
