1. Import the Mobile Ads SDK

1-1. 프로젝트 수준 build.gradle 파일에서 Google의 Maven 저장소를 참조한다.

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

1-2. 앱 수준 build.gradle 파일에서 gradle dependency를 추가한다.

dependencies {
    ...
    compile 'com.google.android.gms:play-services-ads:11.8.0'
    ...
}

최신 버전을 사용해야 한다.

2. Add permission to Manifest

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.tistory.qlyh8.calculator">
 
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
 
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
 
        <activity
            android:name="com.tistory.qlyh8.calculator.MainActivity">
            
            <meta-data 
                android:name="com.google.android.gms.version"
                android:value="@integer/google_play_services_version" />
 
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
       
        <activity android:name="com.google.android.gms.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
            android:theme="@android:style/Theme.Translucent" />
    </application>
</manifest>

3. Initialize MobileAds

import com.google.android.gms.ads.MobileAds;
 
 
public class MainActivity extends AppCompatActivity {
 
    private InterstitialAd mInterstitialAd;
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main)
       
        MobileAds.initialize(this, "ca-app-pub-...~...");
    }

"adMob app ID"로 MobileAds.initialize()를 호출하여 모바일 광고 SDK를 초기화한다.
