Android Getting Extras from Intents

I'm trying to use startActivityForResult() to get a String from another activity, but I keep getting a NullPointerException whenever I try to retrieve the String from the Intent. Here's what I've got:

//To set up the Intent:
String in = mEditText.getText().toString(); //medittext is EditText that I want String from
Intent i = new Intent(this, ActivityLoaderActivity.class); //activity that started this one
i.putExtra("message", in);
setResult(1);
this.finish(); //cause I'm using startActivityForResult()

//To get the String
@Override
protected void onActivityResult( ... , Intent data) {
    String s = data.getStringExtra("message"); //error here
}

I know the error is at getStringExtra() through debugging, but I still can't figure out why it's crashing. Anyone have any ideas?

Maybe you could try using setResult(1, i) and checking in onActivityResult() for the resultCode before getting the extra like this

if(resultCode == 1)
{
   //get String extra
}

Hope it helps
