It's simple, I have a fragment, in onCreate I make a post request, then inside onPostExecute

I call: Intent browserIntent = new Intent (Intent.ACTION_VIEW, Uri.parse (this.redirectUrl + "? username =" + getValue (loginString) + "& password =" + getValue (pwdString))); startActivity (browserIntent);

Swears at this line: startActivity (browserIntent); This is what it says:

What does it omit to be?

    Fragment PlanetFragment {41b92d38} not attached to Activity

    This means that at the time when startActivity(browserIntent); the fragment is no longer attached to Activiti. Need to do something different. You can tell just by looking at the code.
