Unreachable Statement

Question

I need help, on line 107 the android studio shows an error that says:

"Error:(107, 48) error: unreachable statement"

Whereas Line 106 is the AdapterView.AdapterContextMenuInfo info is red. When I remove line 107 which is the int id the line of AdapterView no longer turns red indicating error.

I’ve tried every way but I can’t find the mistake.

List.

The error is here:

public boolean onContextItemSelected(MenuItem item) {
    return super.onContextItemSelected(item);

    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
   int id = lista.get(info.position).getId();

    if(item.getItemId()==1){
        startActivity(new Intent(getBaseContext(), Editar.class).putExtra("id", id));
    }
   return true;

}

In fact, nothing after the first line of the method will be executed, since this first line contains a return, that forces the output of the method. So all the code that follows is unreacheable, that is, it will never be executed.
