# Prebid.js on Android

This article explains how you can connect THEOplayer with Prebid.js. Prebid.js is an open-source header bidding solution. On the client-side, you can request bids from multiple ad networks, take a winning bid and select its associated advertisement. You want to configure and play this selected advertisement in THEOplayer.

Because Prebid.js is a separate library, you can connect it with THEOplayer on any platform that supports both Prebid.js and THEOplayer.

Prebid.js allows you to request bids. This request will respond with bids through a callback function. In this callback function, you have to select a winning bid and extract the ad tag URL. You can configure this URL as THEOplayer's ad source.

## Code example

Refer to <https://docs.prebid.org/prebid-mobile/pbm-api/android/code-integration-android.html> to integrate Prebid on the Android SDK. The same THEOplayer API to configure advertisements is available on the Android SDK, as explained in [How to set up VAST and VMAP ads](https://docs-preview.optiview.dolby.com/pr-863/theoplayer/how-to-guides/android/ads/set-up-vast-and-vmap.md).
