Get Started

Integrating the Google Mobile Ads SDK into an app is the first step toward displaying ads and earning revenue. Once you've integrated the SDK, you can choose an ad format (such as native or rewarded video) and follow the steps to implement it.

Prerequisites

Use Android Studio 1.0 or higher
Target Android API level 14 or higher

Import the Mobile Ads SDK

Apps can import the Google Mobile Ads SDK with a Gradle dependency that points to Google's Maven repository. In order to use that repository, you need to reference it in the app's project-level build.gradle file. Open yours and look for an allprojects section:

Example project-level build.gradle (excerpt)

allprojects {
    repositories {
        google()
        jcenter()
    }
}

Add the google() directive above if it's not already present.

Next, open the app-level build.gradle file for your app, and look for a "dependencies" section.

Example app-level build.gradle (excerpt)

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.google.android.gms:play-services-ads:17.1.1'
}

Add the line in bold above, which instructs Gradle to pull in the latest version of the Mobile Ads SDK. Once that's done, save the file and perform a Gradle sync.

Update your AndroidManifest.xml

Declare that your app is an Ad Manager app by adding the following <meta-data> tag in your AndroidManifest.xml.

<manifest>
    <application>
        <meta-data
            android:name="com.google.android.gms.ads.AD_MANAGER_APP"
            android:value="true"/>
    </application>
</manifest>

Select an ad format

The Mobile Ads SDK is now imported and you're ready to implement an ad. Ad Manager offers a number of different ad formats, so you can choose the one that best fits your app's user experience.

Banner ads are rectangular image or text ads that occupy a spot within an app's layout. They stay on screen while users are interacting with the app, and can refresh automatically after a certain period of time. If you're new to mobile advertising, they're a great place to start.

Interstitial

Interstitials are full-screen ads that cover the interface of an app until closed by the user. They're best used at natural pauses in the flow of an app's execution, such as between levels of a game or just after a task is completed.

Native

Native is a component-based ad format that gives you the freedom to customize the way assets such as headlines and calls to action are presented in your apps. By choosing fonts, colors, and other details for yourself, you can create natural, unobtrusive ad presentations that can add to a rich user experience.

Google Ad Manager offers two ways to implement native ads: Native Styles and Custom Rendering.

Native Styles has been designed to make the implementation of native ads as easy as possible, and it's a great choice if you are new to the format. Custom Rendering has been designed to maximize the freedom you have in creating your presentations.

Rewarded Video

Rewarded video ads are full-screen video ads that users have the option of watching in their entirety in exchange for in-app rewards.
