title: Install Referrer in Unity3D
body: <p>Tell me how you can get install referrer in Unity3D. I made an android plugin in which I created a class inherited from the broadcastreceiver. And in the onreceive method, I send data, but the onreceive method is not called. The receiver has been added to the plugin Manifest and Unity manifest.Manifest:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;receiver
      android:name="com.ahg.and.InstallReferrerReceiver"
      android:exported="true"
      android:permission="android.permission.INSTALL_PACKAGES"&gt;
      &lt;intent-filter&gt;
          &lt;action android:name="com.android.vending.INSTALL_REFERRER" /&gt;
      &lt;/intent-filter&gt;
  &lt;/receiver&gt;
  </code></pre>
  
  <p>BroadcastReceiver:</p>
  
  <pre class="lang-java prettyprint-override"><code>public class InstallReferrerReceiver extends BroadcastReceiver {
      @Override
      public void onReceive(Context context, Intent intent) {
          String referrer = intent.getStringExtra("referrer");
  
          UnityPlayer.UnitySendMessage("Loader", "GetReferrer",referrer);
      }
  }
  </code></pre>
  
  <p>Please tell me, for what reason is not called broadcastreceiver?</p>
