AndroidでAdMobとAdMakerの切り替え

AdMakerのSDKもバージョンが上がって、広告の成否が判断できるようになってました。
優先度を設定して表示するサンプル。
・AdMobのSDKは4.1.1
・AdMakerのSDKは1.1

}

呼び出し元ActivityのOnCreateあたりで

    //広告表示
    new ComAd(this, (RelativeLayout)findViewById(R.id.ad_layout)).loadAd();

呼び出し元Activityのレイアウトの上部か下部に

<RelativeLayout android:id="@+id/ad_layout" android:layout_width="fill_parent" android:layout_height="50dp"></RelativeLayout>

AndroidManifestに以下を忘れずに

        <activity android:name="com.google.ads.AdActivity" android:configChanges="orientation|keyboard|keyboardHidden"></activity>
    </application>
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
