Shared preference in kotlin
I have a error when I try to create a SharedPreference.

My variable sp is always equal null.

I attach my code:

fun saveParameter(){



val sp = getApplicationContext().getSharedPreferences("com.example.user.pocketandroid", Context.MODE_PRIVATE)
val editSp = sp.edit()

editSp.putInt(PORTTEXT,portText.text.toString().toInt())
editSp.putString(PASSWORDTEXT,passwordText.text.toString())
editSp.putString(NAMETEXT,nameText.text.toString())...
