Implement rewarded ads in Android
Implement rewarded ads in your Android app. Load ad content, display it through Java code, and use a listener to manage ad events and reward logic.

Rewarding users for watching ads increases user engagement, resulting in higher revenue. For example, games might reward users with in-game currency, consumables, additional lives, or experience-multipliers. For more information on how to effectively design your rewarded ads, refer to the monetization strategy guide.
To reward users for completing a video ad, use the listener callback method's result to check if the user finished watching the ad and should be rewarded.

Unity Ads requires access to the currently running Activity, so the following example uses .
Because this might not be suitable for all implementations, some customization might be required (depending on the integration).

Rewarded video ad buttons
Using a button to allow the player to opt in to watching an ad is a common implementation for rewarded video ads. Use the following example code to create a rewarded ads button. The ads button displays an ad when pressed, as long as an ad has loaded first. For information on configuring buttons, refer to the Android developer documentation on Buttons.
After you have implemented your button, add a script with the following code, where is a button configured in the View:
