Nutrient 8.6 migration guide

This guide provides the necessary steps for migrating from Nutrient Android SDK 8 to Nutrient Android SDK 8.6.

1. Upgrading Nutrient

   Inside your app/build.gradle.kts file, update the version of the io.nutrient:nutrient dependency to 8.6.0:

   dependencies {
      implementation("io.nutrient:nutrient:8.5.1")
      implementation("io.nutrient:nutrient:8.6.0")
    }

   Upgrading OCR dependencies

   If your project also integrates the [Nutrient OCR library][], make sure to upgrade the version of all OCR dependencies too:

   dependencies {
      implementation("io.nutrient:nutrient-ocr:8.5.1")
      implementation("io.nutrient:nutrient-ocr-english:8.5.1")
      implementation("io.nutrient:nutrient-ocr:8.6.0")
      implementation("io.nutrient:nutrient-ocr-english:8.6.0")
       ...
   }

2. RxJava 2 to RxJava 3

   Nutrient Android SDK 8.6 upgrades ReactiveX Java(opens in a new tab) from major version 2 to 3 (specifically 3.1.6).

   This means users who make use of our asynchronous APIs need to change their imports, replacing import io.reactivex. with import io.reactivex.rxjava3 where applicable.

   For more details on migrating to RxJava 3, see the official migration guide(opens in a new tab).

3. Deprecated symbols removed

   Nutrient Android SDK 8.6 removes the following APIs that were deprecated in previous versions:

   • SignatureFormElement#getOverlappingInkSignature, which was replaced by SignatureFormElement#getOverlappingSignature.
   • The legacy PKCS7 and PKCS7SignatureContents constructors, which have been replaced by constructors that use FilterSubtype:
     • PKCS7#create
     • PKCS7SignatureContents-byte and PKCS7SignatureContents-SignatureFormField
   • PdfThumbnailGrid#setOnDocumentSavedListener, which was replaced by addOnDocumentSavedListener(OnDocumentSavedListener).
   • PdfDrawable#getPDFToPageTransformation and PdfDrawable#updatePDFToViewTransformation, which were replaced by getPdfToPageTransformation and updatePdfToViewTransformation.
