How to get referrer URL for apps downloaded from outside the market

问题

I've found some solutions to track referrer URL from the market, but my apps aren't in the market.

Is there a way to get the referrer URL for applications downloaded from private sites?

回答1:

To get referrer, you need to register your receiver for that. After installation, a broadcast is fired which you need to catch by following code.

First take a look at Android Native Application Tracking Overview

1. Create a Receiver

public class ReferrerReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Bundle extras = intent.getExtras();
        String referrerString = extras.getString("referrer");

        Log.i("Home", "Referrer is: " + referrerString);
    }
}

2. Register in Manifest file

<receiver android:name="your.package.name.ReferrerReceiver" android:exported="true">
<intent-filter>
    <action android:name="com.android.vending.INSTALL_REFERRER" />
</intent-filter>
</receiver>
