# Review Android version requirements

## Advertising ID

If your app uses the IMA SDK version 3.25.1 or higher, the SDK already
automatically declares the `com.google.android.gms.permission.AD_ID` permission
and is able to access the Advertising ID whenever it's available.

For apps that use the IMA SDK version 3.24.0 or lower and are targeting Android
13, you must add the `com.google.android.gms.permission.AD_ID` permission in the
`AndroidManifest.xml` file for the Google Mobile Ads SDK to access the
Advertising ID:

    <manifest>
        <application>
            <meta-data
                android:name="com.google.android.gms.ads.APPLICATION_ID"
                android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"/>

            ...

        </application>
        <!-- For apps targeting Android 13 or higher & IMA SDK version 3.24.0 or lower -->
        <uses-permission android:name="com.google.android.gms.permission.AD_ID"/>
    </manifest>

To learn more about the `com.google.android.gms.permission.AD_ID` permission
declaration, including how to disable it, please refer to this

article.

## App Set ID

Starting with Android 12 devices, Google Play will zero out the advertising ID
when a user opts out of personalization in their Android Settings. Google Play
has also introduced the [App Set ID](https://developer.android.com/training/articles/app-set-id),
which offers a privacy-friendly way to correlate usage or actions across a set
of apps owned by the same organization.

IMA version 3.25.1 or higher includes the App Set ID SDK by default. App Set ID
is essential to support non ads use-cases such as analytics and fraud
prevention, when the advertising ID is zeroed out. For more information on the
App Set ID see this
[Android developer guide](https://developer.android.com/training/articles/app-set-id#scope).
