Get Android Google Analytics referrer tag

We’re planning to use Google Analytics to track ad click-through referrals, through the Android Market, to our application.

According to the Google Documentation the referrer tag comes through via an intent, and is automatically recorded by the Google Analytics library.

That’s great, but we need to extract that referral tag for our own internal analytics. The documentation is shy on details about how to grab it out of the initial launch intent, and instructions on how to simulate this before going live.

Does anyone have experience with this?

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

I went ahead and published a dead pixel finder app to play with snooping on the intent. For some reason, when I registered two different broadcast receivers (ie com.google.android.apps.analytics.AnalyticsReceiver and my own), I never received it on my own.

So instead, I registered only my own receiver, process the information, and pass it along to Google Analytics. Don’t know how kosher this is, but it works. Code follows.

public class ZSGoogleInterceptor extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();

        String referrerString = extras.getString("referrer");
        // Next line uses my helper function to parse a query (eg "a=b&c=d") into key-value pairs
        HashMap<String, String> getParams = Utility.getHashMapFromQuery(referrerString);
        String source = getParams.get("utm_campaign");

        if (source != null) {
            SharedPreferences preferences = context.getSharedPreferences("my_prefs", Context.MODE_PRIVATE);
            Editor preferencesEditor = preferences.edit();
            preferencesEditor.putString("ga_campaign", source);
            preferencesEditor.commit();
        }

        // Pass along to google
        AnalyticsReceiver receiver = new AnalyticsReceiver();
        receiver.onReceive(context, intent);
    }

}

Then, when your application is actually launched, you can pull the value back out of the shared preferences and pass it along with user signup or whatever. I used the campaign tag for my purposes, but you can grab any parameters you want out of the referrer string created with this tool.

        <!-- Make sure this points to the location of Referrer Receiver in your package -->
        <receiver android:name=".ReferrerReceiver" android:exported="true">
