# App Open Ads

> Integrate CloudX App Open ads in Android apps

App Open ads are fullscreen placements intended for app foreground moments, such as when a user returns to your app after it has been backgrounded.

#### Supported Networks

App Open demand is served by the following bidding networks:

| Network   | Adapter                                              |
| --------- | ---------------------------------------------------- |
| Mintegral | [Mintegral](/en/android/adapters/mintegral/overview) |
| Pangle    | [Pangle](/en/android/adapters/pangle/overview)       |
| Vungle    | [Vungle](/en/android/adapters/vungle/overview)       |

The [Google Mobile Ads waterfall adapter](/en/android/adapters/googlewaterfall/overview) also supports App Open placements for AdMob waterfall demand.

          Log.e("CloudX", "App Open ad failed to display: ${cloudXError.message}")
          appOpenAd.load()
      }

          appOpenAd.load()
      }

      override fun onAdClicked(cloudXAd: CloudXAd) {}

      // CloudXAdRevenueListener callback
      override fun onAdRevenuePaid(cloudXAd: CloudXAd) {
          Log.d("CloudX", "App Open bid-time revenue: ${cloudXAd.revenue}")
      }

      override fun onDestroy() {
          super.onDestroy()
          appOpenAd.destroy()
      }
  }
  ```

Use App Open ads sparingly and only at natural app-open or app-resume transitions. Avoid showing one while the user is already interacting with app content.
