Android Google Analytics Campaign tracking not appearing

I’ve been able to integrate Google Analytics into my Android app, but am stuck with campaign tracking. 开发者_运维问答In GA, I see page views, events, and custom variables, but campaign referrals never appear. Is there an additional step that is not documented at code.google.com/mobile/analytics/docs/android? like additional permissions specific to referals? Could be something obvious that I should know, I'm new to Android. Here’s my manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.mytestapp.ga"
  android:versionCode="4"
  android:versionName="4.0">
   <uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application android:icon="@drawable/icon"
             android:label="@string/app_name">

<activity android:name="com.mytestapp.ga.MyActivity"
          android:launchMode="standard">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>

<!-- Used for install referrer tracking -->
<receiver android:name="com.google.android.apps.analytics.AnalyticsReceiver"
          android:exported="true">
  <intent-filter>
    <action android:name="com.android.vending.INSTALL_REFERRER" />
  </intent-filter>
</receiver>

Try testing it out:

And then look at the troubleshooting section if it doesn't work. One thing I forgot was to add the bits of java code. I sortof missed the part where you have to get Google Analytics in general to work first, but it sounds like you have that part covered.
