This guide provides the necessary steps for migrating from Nutrient Android SDK 6.6 to [Nutrient Android SDK 7](/blog/pspdfkit-android-7-adds-real-time-communication/).

Before updating to Nutrient Android SDK 7, make sure your app is running at least Nutrient Android SDK 6.6. 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 7.

**Steps:**

1. ## Upgrading Nutrient

   Inside your `app/build.gradle.kts` file, update the version of the `io.nutrient:nutrient` dependency to `7.0.0`:

   ```diff

   dependencies {
   -   implementation("io.nutrient:nutrient:6.6.2")
   +   implementation("io.nutrient:nutrient:7.0.0")
    }
   ```

   ### 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:6.6.2")
   -   implementation("io.nutrient:nutrient-ocr-english:6.6.2")
   +   implementation("io.nutrient:nutrient-ocr:7.0.0")
   +   implementation("io.nutrient:nutrient-ocr-english:7.0.0")...
   }
   ```

2. ## dropping KitKat support

   Nutrient 7 removed support for running on Android 4.4 KitKat (API 19) devices. The new minimum supported Android version is 5.0 Lollipop (API 21).

   If you previously supported `minSdkVersion 19` within your Android project, inside your `app/build.gradle` file, update the `minSdkVersion` to `21`:

   ```diff

   android {
       defaultConfig {
   -       minSdkVersion 19
   +       minSdkVersion 21
       }
   }
   ```
