I have an edit text from where I am taking the text and sending it to MainActivity using putExtra() but when the getStringExtra() is returning null.

SecondActivity:-

            val intent = Intent(this, MainActivity::class.java)
            if(editWordView.text.isNotEmpty()){
                val word = editWordView.text.toString()
                intent.putExtra("Word", word)
                startActivity(intent)
            }

In first log it is showing null and last line is not executing as the word is null

MainActivity:-

        val intent = Intent()
        val word = intent.getStringExtra("Word")
        Log.d(TAG, "MainActivity: $word")
        word?.let {
            viewModel.insert(Word(word))
            Log.d(TAG, "onCreate: Inserted $word")
        }

Delete:

val intent = Intent()

You are creating a new, empty Intent. That will not contain any extras. Instead, you need to get the Intent from the activity:

• via getIntent() for the Intent used to create the activity
• in onNewIntent() for any Intent used to bring an already-running instance of this activity back to the foreground

To get value in the Second activity you can also try this, it works perfect for me!

val word = intent.extras?.getString("Word")
