This article provides a set of guidelines for migrating from Nutrient Android SDK 5.5 to Nutrient Android SDK 6.0. ## Updated dependencies With Nutrient 6, we updated various dependencies of Nutrient: - **Build System Dependencies** - The Android Gradle plugin used to build Nutrient was updated to version 3.5.0. In addition, all sample applications now use Android Gradle plugin 3.5.0 as well. - Kotlin was updated to version 1.3.50. ## Merge of Nutrient and Instant libraries Starting with Nutrient 6.0, we no longer provide separate libraries for Nutrient and Instant. Instant client code is now part of the Nutrient library. If you are currently using Instant and want to update to 6.0, you need to remove its dependency from your project’s `dependencies` block and add the `OkHttp` dependency, like so: ```diff dependencies { implementation 'com.pspdfkit:pspdfkit:6.0' - implementation 'com.pspdfkit:pspdfkit-instant:5.5.0' + implementation 'com.squareup.okhttp3:okhttp:3.11.0' } ``` ## Notable changes and deprecations ## Dropped deprecated fields and methods Here’s a list of other fields and methods we dropped: - `AnnotationProvider#getAllAnnotationsOfType()` no longer returns `Observable` but now returns `List`. You can use `AnnotationProvider#getAllAnnotationsOfTypeAsync()` instead. - `PdfFragment#getAnnotationDefaults()`. Use `PdfFragment#getAnnotationConfiguration()` instead. - `PdfFragment#setAnnotationDefaultsProvider()`. Use `AnnotationConfigurationRegistry#put()` instead. - `PSPDFKit#setLoggingEnabled()`. To disable logging, remove all loggers via `PdfLog#removeAllLoggers()`. Alternatively, implement a custom logging policy by setting multiple custom `Logger`s via `PdfLog#setLoggers(Logger...)`. - `AnnotationDefaultsManager`. Replaced by `AnnotationConfigurationRegistry`. - `AnnotationDefaultsProvider`. Replaced by `AnnotationConfiguration`. - `com.pspdfkit.annotations.defaults.AnnotationProperty`.

Use `BorderStylePreset#getBorderStyle()` on the border style preset returned via `AnnotationPreferencesManager#getBorderStylePreset()`. - `AnnotationPreferencesManager#setBorderStyle()`. Configure `BorderStyle` in `BorderStylePreset` and set it via `AnnotationPreferencesManager#setBorderStylePreset()`. - `AnnotationPreferencesManager#getBorderDashArray()`.
