Intent's extra is always null

Question

I'm trying to pass an int variable to another activity:

From the current activity:

Intent intent = new Intent(getApplicationContext(),PlayActivity.class);
intent.putExtra("position", position);
startActivity(intent);

At PlayActivity.onCreate:

Intent intent = getIntent();
String position = intent.getStringExtra("position");
int index = Integer.parseInt(position);

Problem is, position is always null (and parseInt() throws exception).
Why?

There is no string extra to get since it is an int. You should have

Intent intent = getIntent();
int position = intent.getIntExtra("position");

I'm not sure why you are trying to get a String then parse to an int when it is sent as an int, assuming position is an int in your first Activity. If that is not the case then please explain a little better.

Somehow I thought you can pass only strings. Thanks! – AngryOliver Jul 07 '14 at 22:12

See the link to the docs I posted. Particularly under the Public Methods and the different `putExtra()` and `getExtra()` methods. You are most welcome. – codeMagic Jul 07 '14 at 22:14
