How to upgrade?
If your app integrates with the Facebook SDK using dynamic versioning in Maven, then you only need to rebuild your project. Upgrading the SDK requires a clean rebuild of your app. Gradle will resolve any dependencies and download the latest SDK for your app.
If your app integrates with the Facebook SDK in Maven but does not use dynamic versioning, upgrade now by modifying your build.gradle file with the following code and rebuild your project.
