Basically it is just set of useful things combined and sorted under 4 categories Foundation Architecture Behavior UI Some of the core things like AppCompat library, Architecture components, Fragments, Animation and transitions and many more were added now in relative categories and these 5 things were newly added. Android Ktx [LINK] The purpose of Android KTX is to make Android development with Kotlin more concise, pleasant, and idiomatic by leveraging Kotlin language features such as extension functions/properties, lambdas, named parameters, and parameter default values Navigation [LINK] The Navigation Architecture Component simplifies the implementation of navigation in an Android app.This

In theory, the Navigation library supports any architecture you might want to use. Out of the box it can handle Activities and Fragments as navigation destinations, but you can plug in your own solution by implementing your own Navigator [LINK] (as an example, see this article [LINK] ). However, quoted / paraphrased from the Google I/O talk on Navigation [this video] : What is my Activity actually meant to do? Right now, some apps are very Activity-heavy, some are Fragment-heavy, or completely in a different system. We're moving towards a model where the Activity is more just an entry point into your app, rather than it being the owner of the content of your app. It's actually just going to store

I solved this by just committing multiple fragment transactions. Works for me supportFragmentManager.beginTransaction().replace(R.id.content, Fragment1(), "f1").addToBackStack(null).commit() supportFragmentManager.beginTransaction().replace(R.id.content, Fragment2(), "f2").addToBackStack(null).commit() supportFragmentManager.beginTransaction().replace(R.id.content, Fragment3(), "f3").addToBackStack(null).commit() supportFragmentManager.beginTransaction().replace(R.id.content, Fragment4(), "f4").commit() However, for a cleaner and better solution you could also have a look at the Jetpack Navigation UI [this video]

I'm trying to work on this new navigation editor introduced as a part of architecture components recently. reference : [this video] I added the depdencies as mentioned in the documentation [LINK] My assumption is that there is a new 'Resource Type' called 'Navigation' introduced. And when I add a 'Navigation' file in my project, android studio will let me view that file in two modes, text and design and I thought that the design mode is the 'Navigation Editor' I tried what was given in the documentation. [LINK] Right click the 'res' folder -> new resource file -> resouce type - 'Navigation'. But, I could not find a resouce type called 'Navigation' However I was able to create a resource directory

You can connect your ActionBar to a NavController using NavigationUI.setupActionBarWithNavController() [LINK] . This is generally done in your Activity, right after you call setSupportActionBar() : supportActionBar = findViewById<Toolbar>(R.id.toolbar) // Get the NavController for your NavHostFragment val navController = findNavController(R.id.nav_host_fragment) // Set up the ActionBar to stay in sync with the NavController setupActionBarWithNavController(navController) This approach is covered in the Navigation talk at Google I/O 2018 [this video] .
