On July/2019 Android Weekend, I have talked about how to check if there are updates available for your Android app dependencies such as the versions of gradle plugins, Kotlin, and libraries that the app depends on.
With gradle-versions-plugin, you can easily check if the updates are available with a single gradle command, so you can easily automate the version checks with CI as well.
The plugin also provides ways to customize the result of the version checks. If you have not tried it yet, I strongly recommend that you check it out :)
