Suddenly, Android Studio started to prompt that to use the Navigation of Android Jetpack is necessary to install a module android.arch.navigation:navigation-fragment:+.. That is the whole module name.
Two problems. One, I already have it installed, version 1.0.0alpha-06 and second, if I attempt to install it will simply say it could not install.
The main issue here is that five minutes before this happened I DID use the visual editor of this, but it suddenly went like this.
I've already tried to clean the cache, invalidate and restart, but it decided to remain like this. Ideas?
