NotesApp | NotesApp using command Line | Command Line Interface library

I have a fragment file. There is an error message

"error: incompatible types: androidx.fragment.app.Fragment cannot be converted to android.app.Fragment. fragmentTransaction.replace(R.id.frame_layout, fragment).addToBackStack(null);"

I know there is something wrong with my build.gradle file but i don't know which dependency should i used. I already read the documentation and questions related but some dependency are deprecated. This is my MainActivity file:

I am trying to understand how to combine react native fast refresh with redux. I have cloned the following project: https://github.com/amandeepmittal/rnReduxhooks

When changing code in the view ViewNotes.js fast refresh works fine. But when changing code in the reducer notesApp.js fast refresh resets the redux state.

How can I prevent that?

Is there a tutorial for react native and redux similar to the ones for react and redux? (https://duske.me/setting-up-hot-module-replacement-with-create-react-app-and-redux/)

Firstly, I am a noob to node.js and JavaScript.

I am trying to write a program that stores the notes of a user in the local system using yargs.

My train of through in the handler is as follows-

1. First create the an object that contains the note's title and its contents.

2. I assume that file is always created in the user's local system and is either going to be empty or have some notes.

3. Get the contents of the file and if it is empty, create an object that has the array of all notes and push the note to it. I then write that to file after doing the necessary JSON manipulations.

4. If an object is already present in the file, I just push the new note to it.

Here is my code

I am facing given warning in console:

Warning: A string ref, "grid", has been found within a strict mode tree. String refs are a source of potential bugs and should be avoided. We recommend using useRef() or createRef() instead.

Here's my line of codes:

Before posting here ,i have spent considerable time to figure it out myself,i have removed various errors though. I am developing a little notesapp ,evrything worked fine until i used fragments in my app which contains a recycler view.The problem is that i cannot pass the data retrieved from database to recyclerview adapter .

the error says "Attempt to invoke virtual method 'void com.example.diary.RecyclerAdapter.setdata(java.util.List)' on a null object reference"

i have verified that the data is not empty ,iam confused why do i get a null pointer error.

relevant codes are posted below.

fragment.java

I am trying to write a unit test for my database, but I am getting the following error. The error says that should not be a null value. Through the Log.i, I can know if variable count is a null value. But I don't know why the variable count was worth null.

I want to add a scrollview inside 1 of my screens and on that same screen. I want to have a button that redirects to the main screen. The code shown below does not seem to be working. This is my python code (assume I have imported the relevant modules):

I am making a Notes app using with Xcode in Swift 3. I have a way to add notes, a way to save, delete, and title notes. When I make notes, they are listed from oldest to newest like so:
