This guide is intended for publishers who are interested in using Google Mobile Ads mediation with **Vpon**. It walks through the setup of a mediation adapter to work with your current Android app and the configuration of additional settings. | Vpon Resources | |---| | [Documentation](http://vpon-sdk.github.io/android/mediation/admob/) | | [SDK](http://vpon-sdk.github.io/android/download/index.html) | | [Adapter](https://vpon-sdk.github.io/android/download/#admob) | | [Customer support](mailto:fae@vpon.com) | ## Prerequisites - An Android app with Google Mobile Ads SDK (Legacy) integrated. (If you don't have one, see [Set up Google Mobile Ads SDK (Legacy)](https://developers.google.com/admob/android/quick-start.md.txt).) - An AdMob account and [an ad unit configured with mediation line items](https://support.google.com/admob/answer/3124703). ## Helpful primers The following Help Center articles provide background information on mediation: - [About AdMob Mediation](https://support.google.com/admob/answer/3063564) - [Set up AdMob Mediation](https://support.google.com/admob/answer/3124703) - [Optimize AdMob Network](https://support.google.com/admob/answer/3534471) ## Add Vpon to your project ### Include network adapter and SDK Download the Vpon SDK and adapter from the [previous links](https://developers.google.com/admob/android/mediation/vpon.md.txt#resources). In Android Studio, include the adapter and SDK files in your project's `libs` folder. Make sure that your app-level Gradle file includes the following: ### Kotlin ```kotlin dependencies { implementation(fileTree(mapOf("dir" to "libs", "include" to listOf("\*.aar", "\*.jar")))) // ... } ``` ### Groovy ```groovy dependencies { implementation fileTree(dir: 'libs', include: \['\*.aar', '\*.jar'\]) // ... } ``` ### Configure the AndroidManifest.xml file Modify your `AndroidManifest.xml` file as instructed in the Vpon documentation. Your app doesn't need to call Vpon directly---Google Mobile Ads SDK (Legacy) calls the Vpon adapter to fetch ads on your behalf. If necessary, you can specify any additional request parameters. The rest of this page details how to provide more information to Vpon. ### Initialize your ad object with an Activity instance In the constructor for a new ad object (for example, [`AdView`](https://developers.google.com/admob/android/reference/com/google/android/gms/ads/AdView.md.txt)), you must pass in an object of type [`Context`](https://developer.android.com/reference/android/content/Context). This `Context` is passed on to other ad networks when using mediation. Some ad networks require a more restrictive `Context` that is of type [`Activity`](https://developer.android.com/reference/android/app/Activity) and may not be able to serve ads without an `Activity` instance. Therefore, we recommend passing in an `Activity` instance when initializing ad objects to ensure a consistent experience with your mediated ad networks.
