Best practice for nested fragments in Android 4

The Android Support Library also now supports nested fragments, so you can implement nested fragment designs on Android 1.6 and higher. Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>. Nested fragments are only supported when added to a fragment dynamically Android Basics - Learn about Nested Fragments A Fragment can contain child Fragments just like an Activity can contain Fragments. For this you need to add the nested fragment programatically. For example in the Employee App, that you have created, in the detail view you can add a nested fragment android-nested-fragments-example Demonstrates a MainActivity that dynamically adds a ParentFragment and this fragment inflates an xml which has several static child fragments using the <fragment> tag

NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android.It is enabled by default. NestedScrollView is used when there is a need for a scrolling view inside another scrolling view.You have seen this in many apps for example when we open a pdf file and when we reached the end of the PDF there is an Ad. That's by clicking the new destination button, you don't have to connect any fragment to the nested graph. Now, how do you navigate to the nested graph? Creating Implicit Deep Link With URI. The answer is simple: Use a deep link. More precisely, use an implicit deep link. Implicit deep links allow you to navigate to any fragment by URI its working fine for the fragments which doesn't have any nested fragments within them. This is the code for the nested fragment B to load it on main screen from fragment A.

  3. Update: tl;dr: nested problems were indeed the problem. Activity with only 2 fragments works great. I'm fairly new to developing for Android and the
  4. Destinations outside of the nested graph, such as those on the root graph, access the nested graph only through its start destination. Taken from: Nested Navigation Graphs. So basically you can only have an action that will navigate to the start destination of a nested graph. No way to access an inner fragment/destination inside a nested graph

Android Navigation Samples. This is a sample app showing the usage of the Android Navigation Component in a Single-Activity-App, with nested Navigation Graphs with multiple back-stacks.; This sample is based on the NavigationAdvancedSample by Google which was initially created as a workaround to handle multiple back stacks with Navigation and a BottomNavigationView Setup. We'll be creating an app that performs a simple transition from one fragment to another with multiple shared elements. In Android Studio, create a new project using the Bottom Navigation Activity project template. File -> New -> New Project -> Bottom Navigation Activity. This template gets us up and running pretty quick since.
