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?

Answer 1

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.
