This guide provides the necessary steps for migrating from Nutrient Android SDK 7 to [Nutrient Android SDK 8](https://www.nutrient.io/blog/pspdfkit-android-8-adds-electronic-signatures-and-jetpack-compose/).

Before updating to Nutrient Android SDK 8, make sure your app is running at least Nutrient Android SDK 7. If you’re running an earlier version, see our [previous migration guides](/guides/android/upgrade.md) first, which will guide you through the necessary update steps up to version 8.

**Steps:**

1. ## Upgrading Nutrient

   Inside your `app/build.gradle.kts` file, update the version of the `io.nutrient:nutrient` dependency to `8.0.0`:

   ```diff

   dependencies {
   -   implementation("io.nutrient:nutrient:7.0.0")
   +   implementation("io.nutrient:nutrient:8.0.0")
    }
   ```

   ### Upgrading OCR dependencies

   If your project also integrates the [Nutrient OCR library](https://www.nutrient.io/guides/android/ocr/overview.md), make sure to upgrade the version of all OCR dependencies too:

   ```diff

   dependencies {
   -   implementation("io.nutrient:nutrient-ocr:7.0.0")
   -   implementation("io.nutrient:nutrient-ocr-english:7.0.0")
   +   implementation("io.nutrient:nutrient-ocr:8.0.0")
   +   implementation("io.nutrient:nutrient-ocr-english:8.0.0")...
   }
   ```

2. ## Replacing Deprecated Symbols

   PSPDFKit 8 for Android marked several symbols as deprecated, and they’ll be removed in a future update in Q4 2021. What follows is the list of all the deprecated symbols, along with their replacements:

   - Renamed: `PdfDrawable#updatePDFToViewTransformation()` to `PdfDrawable#updatePdfToViewTransformation()`

     _The method was renamed due to an inconsistent casing style and now uses the SDK-wide casing._

   - Renamed: `PdfDrawable#getPDFToPageTransformation()` to `PdfDrawable#getPdfToPageTransformation()`

     _The method was renamed due to an inconsistent casing style and now uses the SDK-wide casing._

## Electronic signatures

PSPDFKit 8 for Android introduces the [Electronic Signatures](https://www.nutrient.io/guides/android/signatures.md) component, which provides a new UI and APIs for adding signature annotations. See the [Electronic Signatures migration guide](https://www.nutrient.io/guides/android/migration-guides/migrating-to-electronic-signatures.md) for details on how to migrate away from using the [`SignaturePickerFragment`](https://www.nutrient.io/api/android/nutrient/com.pspdfkit.ui.signatures/-electronic-signature-fragment/index.html).
