The Navigation Architecture Component simplifies implementing navigation, while also helping you visualize your app's navigation flow. As outlined in Within the Project tool window, locate the res folder (app -> res), right-click on it and select the New ->Android Resource File menu option: For this example, the code to achieve these tasks will be added using an onStart() lifecycle method. You can find the latest version of Android Studio The first step to start using the Navigation Components is to create a Navigation Graph resource file.As I mentioned earlier, this file is where we define the different destinations in the app and how they are connected.An app can have more than 1 Navigation Graph and these Navigation Graphs can be nested together.To create a Navigation Graph file, perform a right click from anywhere inside your app module, select the optionThis will open a template to create a new Android resource file.Fill the template by giving the name of your file and use the When you are done, press ok and the Navigation Editor for this file will be opened as shown below.The Navigation editor shown above is divided into 3 different sections. in the In your navigation graph, actions are represented by The recommended way to navigate between destinations is to use the Safe Args In the resulting dialog, name the new fragment SecondFragment and the layout fragment_second before clicking on the Finish button. the Navigation Editor, do the following:Back in the Navigation Editor, notice that Android Studio has added this Figure 1 shows a visual representation of a navigation graph for a sample app Click on a destination to select it, and note the following attributes in the For I encourage you to start building your navigation graph from top to bottom.I find it easier this way because the topmost levels of the use-case diagram will have a small number of destinations.If we add the topmost destinations in the Event Finder app used as an example of this post, we will have something like this:As you can see we have 3 destinations, that are the entry points to the app. Edit the MainActivity.java file and modify it so that it reads as follows: Locate the MainFragment.java file, load it into the code editor and modify the onActivityCreated() method to obtain a reference to the button instance and to configure an onClickListener instance to be called when the user clicks the button: Below, you’ll find a Navigation Graph consisting of three destinations and three actions as it appears in the Navigation Editor.The Navigation component is designed to help you implement Google’s new recommended app structure, where a single Activity “hosts” the Navigation Graph, and all your destinations are implemented as fragments. One of them is the Navigation Architecture Component. If you switch to the “Design” tab, then you’ll notice a house icon, which also marks FirstFragment as the graph’s start destination.If you’d prefer to use a different starting point, then select the Activity or fragment in question, and then select “Set Start Destination” from the “Attributes” panel.Alternatively, you can make this change at the code level:Now we have our destinations, let’s add some user interface elements so that it’s always clear which fragment we’re currently viewing.The next step is linking our destinations via actions.You can create an action in the Navigation Editor using simple drag and drop:There should now be an action arrow linking FirstFragment to SecondFragment. For more information on fragments, see the fragment documentation. In the use case diagram above, a Navigation Destination is equal to the different use cases the user can do.A Navigation Action is a link that connects 1 destination with another.The Navigation Host is a component that knows about all the destinations and actions in the Navigation Graph.In order to start implementing the Navigation Components in your app, you will need to first update the version of Android Studio you are working on to the latest 3.2 Canary build.This will ensure you have all the latest tools such as the Navigation editor available to support you with implementing navigation.
