How to pass integer from one activity to another?

I would like to pass a new value for an integer from one activity to another.
i.e.:

activity B contains an integer[] pics = { R.drawable.1, R.drawable.2, R.drawable.3}

I would like activity A to pass a new value to activity B: integer [] pics = [ R. drawable.a, R.drawable.b, R.drawable.c}

so that somehow through

private void startSwitcher() {
Intent myIntent = new Intent(A.this, B.class);
startActivity(myIntent);


I can set this integer value.

I know this can be done somehow with a bundle, but I am not sure how I could get these values passed from activity A to activity B.

thanks!

Answer

Its simple:

Sender Side:

Intent myIntent = new Intent(A.this, B.class);
myIntent.putExtra("intVariableName", intValue);
startActivity(myIntent);

Receiver Side:

 Intent mIntent = getIntent();
 int intValue = mIntent.getIntExtra("intVariableName", 0);
