Referral not received in google anlytics account

I am trying to receive referral parameters in google analytics account. But, it seems referrals are not received and the source and medium is direct\none.

try{
Bundle extras=null;
String referralString=extras.getString("referrer");
tracker.setReferrer(referralString);
}catch(Exception e){}

For the above code dummy parameters in the referral link are

source=sourcexyz
medium=referral
name=product.

Are, the above parameters okie? What am i missing? If the referrerString was wrong then i would get exception, but I am not getting any exception.

What are the preconditions 开发者_JAVA技巧to receive referral parameters in google anlytics account or Receieve data in referring sites, for android mobile device.

You'll need to register the receiver, AnalyticsReceiver.

You can see how to do that, and the different campaign parameters here - but setReferrer() may be enough depending upon what you are looking for.
