Android INSTALL_REFERRER BroadcastReceiver not registering

For the last few days I have been attempting to get a simple INSTALL_REFERRER BroadcastReceiver test to work. But for whatever reason regardless of what I do I can't seem to get my broadcast receiver to register statically via the XML as such:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://ift.tt/nIICcg"
    package="com.packagepath" >

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
        android:name="com.packagepath.CustomApplication"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MyActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

    <!-- Used for Google Play Store Campaign Measurement-->;
    <receiver android:name=".CustomReceiver"
        android:enabled="true"
        android:exported="true">
        <intent-filter>
            <action android:name="com.android.vending.INSTALL_REFERRER" />
        </intent-filter>
    </receiver>
</manifest>

I'm 100% sure that the package names are correct. However, the only time my application will register a receiver is if I do it manually in my code like so:

protected void onResume() {
    super.onResume();
    if (cr == null)
        cr = new CustomReceiver();
    IntentFilter ir = new IntentFilter("com.android.vending.INSTALL_REFERRER");
    registerReceiver(cr, ir);

    Intent i = new Intent("com.android.vending.INSTALL_REFERRER");
    i.setPackage("com.packagepath");
    i.putExtra("referrer", "test");
    sendBroadcast(i);
}

For reference here is the CustomReceiver's code:

public class CustomReceiver extends BroadcastReceiver {

    private static final String D_TAG = "CustomBR";

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.e(D_TAG, "CustomReceiver onReceive (context, intent)");
    }
}

I'm also having issues sending broadcast intents to the device via ADB. But once again for whatever reason I cannot get the broadcast to receive my application. I have tried numerous variations of the below examples with now luck. (note: the only thing that is changed is the packagepath)

am broadcast -a com.android.vending.INSTALL_REFERRER -n com.packagepath/.CustomReceiver

am broadcast -a com.android.vending.INSTALL_REFERRER -n com.packagepath/com.packagepath.CustomReceiver --es "referrer" "utm_source=testSource&utm_medium=testMedium&utm_term=testTerm&utm_content=testContent&utm_campaign=testCampaign"

am broadcast -a com.android.vending.INSTALL_REFERRER -n com.packagepath/.CustomReceiver --es "referrer" "utm_source=testSource&utm_medium=testMedium&utm_term=testTerm&utm_content=testContent&utm_campaign=testCampaign"

The absolute only time I actually get the BroadcastReceiver to call is if I both manually register the receiver and manually invoke a broadcast within the application. Can someone please let me know what I'm doing wrong because I've been searching for days now and can't figure it out. Thank you!
