clear navigation stack after navigating to another fragment
In this tutorial we will discuss about Android Navigation library which is part of Jetpack. This library help us in managing navigation in our android app by creating single Activity, Navigation graph etc. But as you start using Android Navigation you may face few problems. So we will discuss about one problem in this post.
So if we want to navigate to another fragment and we want to clear stack (remove all fragments which were opened previously) then we can tweak this by simply navigating to root of Navigation with the help of Navigation graph and then navigate to our destination fragment. Fortunately we don’t need to this all stuff manually. We can do it easily with following method.
In your Navigation Graph add new Action from Fragment1 to Fragment2 and inside that action add following properties popUpTp=”Navigation_Graph_Id” and popUpToInclusive=”true” and rebuild your project. After rebuilding project navigate to that newly created direction and that’s it.
Here is complete Example:
Code of res/navigation/main_graph.xml
After pasting above code in Navigation Graph, rebuild your project. Now do the following in current fragment
Now you will redirect from SecondFragment to ThirdFragment and FirstFragment and SecondFragment will be cleared from stack.
