--- title: "Nutrient 6.3 migration guide" canonical_url: "https://www.nutrient.io/guides/android/migration-guides/pspdfkit-6-3-migration-guide/" md_url: "https://www.nutrient.io/guides/android/migration-guides/pspdfkit-6-3-migration-guide.md" last_updated: "2026-06-09T10:25:14.344Z" description: "Discover the latest Nutrient 6.3 updates, including build version changes, updated dependencies, and improved MenuItem ID organization for Android." --- ## Updated build versions With Nutrient 6.3, we updated various build properties and versions. - **Build System Dependencies** - The Android Gradle plugin used to build Nutrient was updated to version `3.6.2`. In addition, all sample applications now use Android Gradle plugin `3.6.2` as well. ## Updated dependencies With Nutrient 6.3, we updated multiple transitive dependency versions: - `org.jetbrains.kotlin:kotlin-stdlib` was updated to version `1.3.71` - `io.reactivex.rxjava2:rxjava` was updated to version `2.2.7` - `io.reactivex.rxjava2:rxandroid` was updated to `2.1.1` - `com.getkeepsafe.relinker:relinker` was updated to `1.4.1` ## Changes to MenuItem IDs With Nutrient Android SDK 6.3, we cleaned up the IDs used for [`MenuItem`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui.toolbar.grouping.presets/-menu-item/index.html)s a bit by making it more obvious which ones to use for group items. All items that contain subitems now use IDs that include the word `group`. - `pspdf__annotation_creation_toolbar_item_markup` was renamed to `pspdf__annotation_creation_toolbar_group_markup`. - `pspdf__annotation_creation_toolbar_item_writing` was renamed to `pspdf__annotation_creation_toolbar_item_writing`. - `pspdf__annotation_creation_toolbar_item_drawing` was renamed to `pspdf__annotation_creation_toolbar_item_drawing`. - `pspdf__annotation_creation_toolbar_item_multimedia` was renamed to `pspdf__annotation_creation_toolbar_group_multimedia`. - `pspdf__annotation_creation_toolbar_item_undo_redo` was renamed to `pspdf__annotation_creation_toolbar_group_undo_redo`. - `pspdf__annotation_editing_toolbar_item_inspector` was renamed to `pspdf__annotation_editing_toolbar_group_inspector`. - `pspdf__annotation_editing_toolbar_item_undo_redo` was renamed to `pspdf__annotation_editing_toolbar_group_undo_redo`. - `pspdf__annotation_editing_toolbar_item_copy_cut` was renamed to `pspdf__annotation_editing_toolbar_group_copy_cut`. - `pspdf__annotation_editing_toolbar_item_edit_share` was renamed to `pspdf__annotation_editing_toolbar_group_edit_share`. - `pspdf__document_editing_toolbar_item_more` was renamed to `pspdf__document_editing_toolbar_group_more`. Use of the old IDs or any other ID when creating a [`MenuItem`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui.toolbar.grouping.presets/-menu-item/index.html) with submenu IDs will result in an error being logged. Starting with Nutrient Android SDK 7, this will also throw an exception. --- ## Related pages - [10 3 Migration Guide](/guides/android/migration-guides/10-3-migration-guide.md) - [10 4 Migration Guide](/guides/android/migration-guides/10-4-migration-guide.md) - [10 5 Migration Guide](/guides/android/migration-guides/10-5-migration-guide.md) - [2024 9 Migration Guide](/guides/android/migration-guides/2024-9-migration-guide.md) - [2024 8 Migration Guide](/guides/android/migration-guides/2024-8-migration-guide.md) - [Pspdfkit 2 1 Migration Guide](/guides/android/migration-guides/pspdfkit-2-1-migration-guide.md) - [Migrate to electronic signatures](/guides/android/migration-guides/migrating-to-electronic-signatures.md) - [Nutrient 10 Migration Guide](/guides/android/migration-guides/nutrient-10-migration-guide.md) - [Pspdfkit 2024 2 Migration Guide](/guides/android/migration-guides/pspdfkit-2024-2-migration-guide.md) - [Pspdfkit 2024 1 Migration Guide](/guides/android/migration-guides/pspdfkit-2024-1-migration-guide.md) - [Pspdfkit 2024 3 Migration Guide](/guides/android/migration-guides/pspdfkit-2024-3-migration-guide.md) - [Pspdfkit 2024 4 Migration Guide](/guides/android/migration-guides/pspdfkit-2024-4-migration-guide.md) - [Pspdfkit 2024 7 Migration Guide](/guides/android/migration-guides/pspdfkit-2024-7-migration-guide.md) - [Pspdfkit 2024 6 Migration Guide](/guides/android/migration-guides/pspdfkit-2024-6-migration-guide.md) - [Pspdfkit 4 4 Migration Guide](/guides/android/migration-guides/pspdfkit-4-4-migration-guide.md) - [Pspdfkit 3 1 Migration Guide](/guides/android/migration-guides/pspdfkit-3-1-migration-guide.md) - [Migrate to Nutrient 3.0 with ease](/guides/android/migration-guides/pspdfkit-3-migration-guide.md) - [Pspdfkit 5 1 Migration Guide](/guides/android/migration-guides/pspdfkit-5-1-migration-guide.md) - [Pspdfkit 5 2 Migration Guide](/guides/android/migration-guides/pspdfkit-5-2-migration-guide.md) - [Pspdfkit 5 3 Migration Guide](/guides/android/migration-guides/pspdfkit-5-3-migration-guide.md) - [Pspdfkit 6 1 Migration Guide](/guides/android/migration-guides/pspdfkit-6-1-migration-guide.md) - [Pspdfkit 5 5 Migration Guide](/guides/android/migration-guides/pspdfkit-5-5-migration-guide.md) - [Migration guide for Android SDK 4 features](/guides/android/migration-guides/pspdfkit-4-migration-guide.md) - [Pspdfkit 6 2 Migration Guide](/guides/android/migration-guides/pspdfkit-6-2-migration-guide.md) - [Pspdfkit 7 Migration Guide](/guides/android/migration-guides/pspdfkit-7-migration-guide.md) - [Pspdfkit 6 4 Migration Guide](/guides/android/migration-guides/pspdfkit-6-4-migration-guide.md) - [Pspdfkit 5 Migration Guide](/guides/android/migration-guides/pspdfkit-5-migration-guide.md) - [Pspdfkit 8 7 Migration Guide](/guides/android/migration-guides/pspdfkit-8-7-migration-guide.md) - [Pspdfkit 6 Migration Guide](/guides/android/migration-guides/pspdfkit-6-migration-guide.md) - [Pspdfkit 6 6 Migration Guide](/guides/android/migration-guides/pspdfkit-6-6-migration-guide.md) - [Pspdfkit 8 6 Migration Guide](/guides/android/migration-guides/pspdfkit-8-6-migration-guide.md) - [Pspdfkit 8 9 Migration Guide](/guides/android/migration-guides/pspdfkit-8-9-migration-guide.md) - [Pspdfkit 8 Migration Guide](/guides/android/migration-guides/pspdfkit-8-migration-guide.md) - [Pspdfkit 8 8 Migration Guide](/guides/android/migration-guides/pspdfkit-8-8-migration-guide.md) - [Upgrading](/guides/android/advanced-integration/upgrading.md)
