Error: onActivityResult overrides nothing

Question

I am programming a speech recognition app in Kotlin for Android.

class MainActivity : AppCompatActivity() {
    public override fun onCreate(savedInstanceState:         


        

Answer 1

Replace

override fun onActivityResult(requestCode:Int, resultCode:Int, data:Intent)

With below code, to make Intent object nullable.

override fun onActivityResult(requestCode:Int, resultCode:Int, data:Intent?)

As Intent is declared nullable in parent Activity class. Here is the sample code:

protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data)
