How do I get extra data from intent on Android?

Question

How can I send data from one activity (intent) to another?

I use this code to send data:

Intent i=new Intent(context,SendMessage.class);
i.putExtra(\         


        

Answer 1

Kotlin

First Activity

val intent = Intent(this, SecondActivity::class.java)
intent.putExtra("key", "value")
startActivity(intent)

Second Activity

val value = getIntent().getStringExtra("key")

Suggestion

Always put keys in constant file for more managed way.

companion object {
    val PUT_EXTRA_USER = "PUT_EXTRA_USER"
}
