Admob allows to send custom property values ​​for direct campaign delivery, for example a weather app wants to deliver a banner when the temperature is below _X_ degrees.
Bundle extras = new Bundle();
extras.putInteger("temperature_now", 9);
AdRequest request = new AdRequest.Builder() .addNetworkExtrasBundle(AdMobAdapter.class, extras).build();
Is there any specific reason why the functionality of sending custom fields for direct campaigns has not been implemented?
