Sending data from one activity to another in android studio using kotlin....

Note: make sure the activity ur sending the data is the activity u will receive it else you will get errors.thanks


First activity

 i.putExtra("id",mauth.currentUser!!.uid)
 i.putExtra("email",mauth.currentUser!!.email)

 For a better Example

btn.setOnClickListener {    toast("Logging In")
    mauth!!.signInWithEmailAndPassword(email.text.toString().trim(),

          password.text.toString().trim())
        .addOnCompleteListener(this){ task->            if (task.isSuccessful){
                toast("Login successful")
                val i = Intent(this, Home::class.java)
                i.putExtra("id",mauth.currentUser!!.uid)
                i.putExtra("email",mauth.currentUser!!.email)
                i.putExtra("emailchecker",email.text.toString().trim())
                startActivity(i)
            }
            else {
                toast("Invalid Credentials Or User Not Registered")
            }
        }}
