startActivity and startSubActivity

Question

Can anyone tell me the difference between startActivity and startActivityForResult?

Is startActivity used to call Activity asynchronously and startActivityForResult for a synchronous call?

Are startActivity(intent) and startActivityForResult(intent,-1) same?

Is this question from oDesk "Google Android programming test"? :) :) — Paresh Mayani, Nov 07 '11 at 13:11

Both startActvity() and startActivityForResult() are ASYNCHRONOUS.

There is no startSubActivity() in Android. It was replaced a long time ago by startActivityForResult().

There is no startSubActivity() in Android. It was replaced a long time ago by startActivityForResult().
The difference between them is that:
startActivityForResult() starts an activity and expects something in return; startActivity() just starts an activity without worrying about getting any result.
No. Both startActvity() and startActivityForResult() are ASYNCHRONOUS.
Yes. startActivity(intent) and startActivityForResult(intent,-1) do the same.
