Integrate i-mobile with mediation

This guide shows you how to use the Google Mobile Ads SDK to load and display ads from i-mobile using mediation, covering waterfall integrations. It covers how to add i-mobile to an ad unit's mediation configuration, and how to integrate the i-mobile SDK and adapter into a Unity app.

The dashboard interface for i-mobile uses Japanese text for its labels, buttons, and descriptions. The screenshots in this guide have not been translated. In this guide's descriptions and instructions however, labels and buttons are translated with their English language equivalents in parentheses.
