   package SimpleDemo.ReferralTrack; 

   import java.io.UnsupportedEncodingException;
   import java.net.URLDecoder;
   import java.util.HashMap;
   import java.util.Map;

   import android.content.BroadcastReceiver;
   import android.content.Context;
   import android.content.Intent;
   import android.content.SharedPreferences;
   import android.os.Bundle;

  public class ReferralReceiver extends BroadcastReceiver
   {
@Override
public void onReceive(Context context, Intent intent)
{
    // Workaround for Android security issue: http://code.google.com/p/android/issues/detail?id=16006
    try
    {
        final Bundle extras = intent.getExtras();
        if (extras != null) {
            extras.containsKey(null);
        }
    }
    catch (final Exception e) {
        return;
    }

    Map<String, String> referralParams = new HashMap<String, String>();

    // Return if this is not the right intent.
    if (! intent.getAction().equals("com.android.vending.INSTALL_REFERRER")) { //$NON-NLS-1$
        return;
    }

    String referrer = intent.getStringExtra("referrer"); //$NON-NLS-1$
    if( referrer == null || referrer.length() == 0) {
        return;
    }

    try
    {    // Remove any url encoding
        referrer = URLDecoder.decode(referrer, "x-www-form-urlencoded"); //$NON-NLS-1$
    }
    catch (UnsupportedEncodingException e) { return; }

    // Parse the query string, extracting the relevant data
    String[] params = referrer.split("&"); // $NON-NLS-1$
    for (String param : params)
    {
        String[] pair = param.split("="); // $NON-NLS-1$
        referralParams.put(pair[0], pair[1]);
    }

    ReferralReceiver.storeReferralParams(context, referralParams);
}

private final static String[] EXPECTED_PARAMETERS = {
    "utm_source",
    "utm_medium",
    "utm_term",
    "utm_content",
    "utm_campaign"
};
private final static String PREFS_FILE_NAME = "ReferralParamsFile";

/*
 * Stores the referral parameters in the app's sharedPreferences.
 * Rewrite this function and retrieveReferralParams() if a
 * different storage mechanism is preferred.
 */
public static void storeReferralParams(Context context, Map<String, String> params)
{
    SharedPreferences storage = context.getSharedPreferences(ReferralReceiver.PREFS_FILE_NAME, Context.MODE_PRIVATE);
    SharedPreferences.Editor editor = storage.edit();

    for(String key : ReferralReceiver.EXPECTED_PARAMETERS)
    {
        String value = params.get(key);
        if(value != null)
        {
            editor.putString(key, value);
        }
    }

    editor.commit();
}

/*
 * Returns a map with the Market Referral parameters pulled from the sharedPreferences.
 */
public static Map<String, String> retrieveReferralParams(Context context)
{
    HashMap<String, String> params = new HashMap<String, String>();
    SharedPreferences storage = context.getSharedPreferences(ReferralReceiver.PREFS_FILE_NAME, Context.MODE_PRIVATE);

    for(String key : ReferralReceiver.EXPECTED_PARAMETERS)
    {
        String value = storage.getString(key, null);
        if(value != null)
        {
            params.put(key, value);
        }
    }
    return params;
}
}

After that i have try in my activity

 SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(DemoActivity.this);
              String  referrers1 =preferences.getString("ga_campaign", "0");
              Map<String, String> retrieveReferralParams=ReferralReceiver.retrieveReferralParams(DemoActivity.this);
              String  referrers2= retrieveReferralParams.get("utm_source");
              String  referrers3= retrieveReferralParams.get("utm_medium");
              String  referrers4= retrieveReferralParams.get("utm_term");
              String  referrers5= retrieveReferralParams.get("utm_content");
              String  referrers6= retrieveReferralParams.get("utm_campaign");
              tv.setText(referrers1+" "+referrers2+" "+referrers3+" "+referrers4+" "+referrers5+" "+referrers6+" ");

Not sure that Google lets you send arbitrary information. Try using the generator to create the url.
