How to send data inbetween the activities

#1

we have to send data between two activities, using onActivityResult

#2

This method is depreacaed but still you can use like code mentioned below.
In Main Activity start activity for result like below snippet.

startActivityForResult(Intent(this@MainActivity,ResultActivity::class.java),123)

And also override on Activity result method in Main Activity like below snippet .

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    when (requestCode) {
        123 -> {
            if (resultCode == RESULT_OK) {
                val returnValue = data?.getStringExtra("some_key")
                Toast.makeText(baseContext, returnValue, Toast.LENGTH_SHORT).show()
            }
        }
    }
}

Create a another activity let say ResultActivity and write a function like below snippet which should be called when you want to send back result (i.e any data) .

private fun setTResult() {
    val resultIntent = Intent()
    resultIntent.putExtra("some_key", "Android course from coding block")
    setResult(RESULT_OK, resultIntent)
    finish()
}

You can send any data in intent.
