I am trying to use AWS Amplify, and Android Navigation with Safe Args for Java. My project compiles properly, but crashes at runtime. The error indicates that the problem lies in the navigation classes, and playing with the modules I was using I found out that the other module causing the conflict is the one for AWS Amplify. I read on the Official website that I should in this case remove the navigation library since it seems to already be included in the Amplify library. Can I still use the Navigator if I remove the implementation lines in my gradle files? Is there another way to fix this? The objective is just to be able to use both Navigation and Amplify in the same project. Thank you for the help :)
I am using Android Studio Bumblebee 2021.1.1 Patch 3 and my project is for Android 8.1 (Oreo).

I also added the android.useAndroidX=true and android.enableJetifier=true lines in gradle.properties.

Go to the documentation to learn how to Fix dependency resolution errors.
You can't mix and match navigation-fragment:2.4.2 (from your dependency) and navigation-fragment-ktx:2.3.4 (from Amplify) - all navigation artifacts need to be the same version.
So just change your dependencies to use the -ktx versions of each artifact, thus ensuring that both the version you specifically depend on and the version pulled in from Amplify are the same.
