---

This article provides a set of guidelines for migrating from version 5.0 to version 5.1 of Nutrient Android SDK. If you’re upgrading from a version earlier than 5.0, review the [Android 5 migration guide](https://www.nutrient.io/guides/android/migration-guides/pspdfkit-5-migration-guide.md) first.

## AndroidX

Nutrient Android SDK now uses AndroidX instead of the support library, which means you’ll have to migrate your applications in order to continue using Nutrient. The complete migration instructions can be found [here](https://developer.android.com/jetpack/androidx/migrate). You can let Android Studio automatically migrate your project.

However, you might still need to manually update a few things afterward before everything is working properly.

## Notable changes and deprecations

- `XfdfFormatter#writeXfdf[Async]()` now throws an exception when an annotation that isn’t attached to the document is passed in.

- Deprecates `TextSearch` constructors taking `Context`. Use other overloads instead.

- Deprecates the `SearchOptions.Builder()` constructor taking `Context`. Use the default constructor instead.

- Deprecates `isShareEnabled()` in `PdfActivityConfiguration`. Use `PdfConfiguration#getEnabledShareFeatures()` instead.

- Deprecates `enableShare()` and `disableShare()` in `PdfActivityConfiguration.Builder`. Use `PdfActivityConfiguration.Builder#setEnabledShareFeatures()` instead.

- Deprecates `isTextSharingEnabled()`, `isEmbeddedFilesSharingEnabled`, and `isSharingNoteEditorContentEnabled()` in `PdfConfiguration`. Use `PdfConfiguration#getEnabledShareFeatures()` instead.

- Deprecates `textSharingEnabled()`, `embeddedFileSharingEnabled()`, and `sharingNoteEditorContentEnabled` in `PdfConfiguration.Builder`. Use `PdfConfiguration.Builder#setEnabledShareFeatures()` instead.

## Java 8 support

Since Nutrient Android SDK 5, apps including Nutrient need to enable Java 8 support. In order to enable Java 8 support, follow the instructions below.

1. Make sure you’re using version `3.2.1` or higher of the Android Gradle plugin. In your top-level `build.gradle` file, add:

   ```groovy

   classpath 'com.android.tools.build:gradle:3.2.1'
   ```

2. In your app-level `build.gradle` file, enable Java 8 support:

   ```groovy

   compileOptions {
       sourceCompatibility JavaVersion.VERSION_1_8
       targetCompatibility JavaVersion.VERSION_1_8
   }
   ```
