Send data from activity to fragment in Android

Question

I have two classes. First is activity, second is a fragment where I have some EditText. In activity I have a subclass with async-task and in method doInBa

Answer 1

I ran into a similar issue while using the latest Navigation architecture component. Tried out all the above-mentioned code with passing a bundle from my calling activity to Fragment.

The best solution, following the latest development trends in Android, is by using View Model (part of Android Jetpack).

Create and Initialize a ViewModel class in the parent Activity, Please note that this ViewModel has to be shared between the activity and fragment.

Now, Inside the onViewCreated() of the fragment, Initialize the Same ViewModel and setup Observers to listen to the ViewModel fields.

Here is a helpful, in-depth tutorial if you need.
