To fix it complete the following steps from Android configuration section to resolve Appodeal's dependencies:

  1. After the import Appodeal Unity Plugin, in the Unity editor select File → Build Settings → Android.

  2. Add flag Custom Gradle Template for Unity 2017.4 - Unity 2019.2 versions or Custom Main Gradle Template for Unity 2019.3 or higher (Build Settings → Player Settings → Publishing settings).

  3. Enable the setting "Patch mainTemplate.gradle" (Assets → External Dependency Manager → Android Resolver → Settings).

  4. Enable the setting "Use Jetifier" (Assets → External Dependency Manager → Android Resolver → Settings).

  5. Then run Assets → External Dependency Manager → Android Resolver and press Resolve or Force Resolve.

  6. As a result, the modules, that are required for the Appodeal SDK support, will be imported to project's mainTemplate.gradle file.
