Quick Start

Edit AndroidManifest.xml and config Admob APP ID

This configuration is reqired by admob from version 17.0,APP will crash if not config .Add a meta-data tag in application and set value to your admob appid

 <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-xxxxxxxxxxxxxxxxxx~xxxxxxxxxxxx"/>

Sample code

  <application  android:theme="@style/UnityThemeSelector" 
   android:icon="@drawable/app_icon" 
   android:label="@string/app_name" >
	       <activity
	    android:name="com.unity3d.player.UnityPlayerActivity"
	    android:label="@string/app_name" >
	    <intent-filter>
	    <action android:name="android.intent.action.MAIN" />
	    <category android:name="android.intent.category.LAUNCHER" />
	    </intent-filter>
	    </activity>
	    <meta-data
	    android:name="com.google.android.gms.ads.APPLICATION_ID"
	    android:value="ca-app-pub-3940256099942544~3347511713"/>
  </application>

Edit Info.plist ,add appid

<key>GADApplicationIdentifier</key>
<string>ca-app-pub-xxxxxxxxxxxxxxxxxxxxxx~xxxxxxxxxxxxxx</string>

Config exported Xcode project ,Build Settings->Other Linker Flags ,add flag -ObjC 

1.Init Admob Unity Plugin

Create A C# script ,drag the script to a object on scene , add the follow code in the script file

using admob;
Admob.Instance().initSDK(new AdProperties());//admob id configed in meta,not support in code any more

You can set admob properties as follow ,you need set properties you want to set

    AdProperties adProperties = new AdProperties();
    adProperties.isTesting(true);//true for test ads
    adProperties.isAppMuted(true);
    adProperties.isUnderAgeOfConsent(false);
    adProperties.appVolume(100);
    adProperties.maxAdContentRating(AdProperties.maxAdContentRating_G);
    string[] keywords = { "key1", "key2", "key3" };
    adProperties.keyworks(keywords);

2.Add Admob Banner in Unity App

Here is the minimal code needed to show admob banner.

Admob.Instance().showBannerRelative("your admob banner unit id",AdSize.BANNER, AdPosition.BOTTOM_CENTER, 0);

or you can create another banner by set banner name

Admob.Instance().showBannerAbsolute("ca-app-pub-3940256099942544/6300978111",AdSize.BANNER, 20, 220,"mybanner");

The AdPosition class specifies where to place the banner. AdSize specifies witch size banner to show

3.Remove Banner

By default, banners are visible. To hide a banner, call:

Admob.Instance().removeBanner();

4.How to integrate Interstitial into Unity 3d app?

Here is the minimal code to create an interstitial.

Admob.Instance().loadInterstitial("Your admob interstitial unit id");

Unlike banners, interstitials need to be explicitly shown. At an appropriate stopping point in your app, check that the interstitail is ready before showing it:

if (Admob.Instance().isInterstitialReady()) {
  Admob.Instance().showInterstitial();
}

5.Custom Admob Banner Ad Sizes

In addition to constants on AdSize, you can also create a custom size:

//Create a 250x250 banner.
AdSize adSize = new AdSize(250, 250);
Admob.Instance().showBannerAbsolute("Your admob banner id",adSize,0,30,"bannerName");

6.How to integrate Admob Rewarded Video to Unity3d app?

Here is the minimal code to create an admob video.

Admob.Instance().loadRewardedVideo("ca-app-pub-3940256099942544/1712485313");

Simular with interstitial,video need to be explicitly shown at an appropriate stopping point in your app, check that the video is ready before showing it:

if (Admob.Instance().isRewardedVideoReady()) {
  Admob.Instance().showRewardedVideo();
}

7.Show Admob Native Advanced Ad in IOS and Android App

Here is the minimal code needed to show admob banner. This is implemented with Admob Native Ads Advanced (Unified)

Admob.Instance().showNativeBannerRelative("Your native banner id",new AdSize(360,100), AdPosition.BOTTOM_CENTER);

8.Ad Events

Both Banner and Interstitial contain the same ad events that you can register for. Here we'll demonstrate setting ad events on a interstitial,and show interstitial when load success:

Admob.Instance().interstitialEventHandler += onInterstitialEvent;
void onInterstitialEvent(string eventName, string msg)
{
    Debug.Log("handler onAdmobEvent---" + eventName + "   " + msg);
    if (eventName == AdmobEvent.onAdLoaded)
    {
        Admob.Instance().showInterstitial();
    }
}

You only need to register for the events you care about.
