Thus, this interface is conveniently implemented in the release build with the Crashlytics call shown before and in the debug build as follows: NavTrackerLogDebug : NavTrackerLog Īs the last step, NavTracker is set to all the available NavController(s), by calling addOnDestinationChangedListener on them and supplying the instance of NavTracker: findNavController(R.id.your_nav_host_fragment). It has NavTrackerLog as a dependency that hides the layer in which the data is printed out making it that way build-dependant. In the Cookpad Android app, we have a class called NavTracker which implements NavController.OnDestinationChangedListener and it is in charge of extracting all the relevant data of the current destination and its associated Bundle. In Cookpad we use Crashlytics, which makes it pretty easy to send the information and attach it to the right user session: FirebaseCrashlytics.getInstance().log(destinationData.toString())Ĭreating a mechanism for logging the navigational flow is quite easy if you use the Android Navigation component.
Import 7.app.It’s handy to be able to log the navigation path of the users and make its rendering layer dependant on the build type.įor debug builds, during development, printing the navigation flow to the Android logcat can help to get familiar with the relations between fragments and screens: sometimes it is not easy to link a view with its component representation, as for big apps, the teams don’t usually know the details of the implementation of each screen.įor release builds, when a crash is reported on production, having the navigation path alongside the stacktrace can help to spot quicker what’s the cause of the bug. Step 3 − Add the following code to src /MainActivity.java package onAttach()The fragment instance is associated with an activity instance.The fragment and the activity is not fully initialized. The fragment’s view hierarchy becomes part of, or attaches to, the host’s view. Fragments cannot live on their own-they must be hosted by an activity or another fragment. A fragment defines and manages its own layout, has its own lifecycle, and can handle its own input events. Step 2 Put the Application name and the company domain. A Fragment represents a reusable portion of your app's UI. Step 1 Open an Android Studio and start a new project.
Hi guys, I created in my Android project a. In the above code, we have taken button views and linear layout to show different fragments. Carefully follow my steps to work with the multiple activities and navigate the activities in an Android Studio. Previous Breakpoint not hitting in Xamarin Debugger with Visual Studio 2017 in Dell Vostro 1450 Laptop. Creating the Second Fragment Layout Add a second new Android XML layout resource file to the project, once again selecting a RelativeLayout as the root element. Step 2 − Add the following code to res/layout/activity_main.xml. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
