[umair...@gmail.com]

Hi, I am using unity 2017 & unity 2018.
recently you have mentioned that if you are using "If your app uses Ad Manager instead of AdMob, add the following <meta-data> tag to the AndroidManifest.xml file in the Assets/Plugins/Android/GoogleMobileAdsPlugin directory of your Unity app, instead of the tag shown above."
then add this line, otherwise add AppId in manifest. what does it means, 
As I am making mediation of different ad networks. which technique should I use

Hi Umair,

Thank you for reaching out to us. We are here to assist you with your concern.

To answer your question: if you are using the Google Ad Manager SDK along with the Mobile Ads SDK, then you must use the second set of metadata as described in this page. Specifically:

<manifest>

    <application>

        <meta-data

            android:name="com.google.android.gms.ads.AD_MANAGER_APP"

            android:value="true"/>

    </application>

</manifest>

However, if you are only using the Mobile Ads SDK by itself, then you must use only the first set of metadata. Specifically:

<manifest>

    <application>

        <!-- Your AdMob app ID will look similar to this

        sample ID: ca-app-pub-3940256099942544~3347511713 -->

        <meta-data

            android:name="com.google.android.gms.ads.APPLICATION_ID"

            android:value="YOUR_ADMOB_APP_ID"/>

    </application>

</manifest>

Let us know if you have any other questions.
