android - Unity で Facebook プラグインを使用すると ActivityNotFoundException が発生する

Question

Unity 5.2.2p2、Facebook Unity SDK 7.2.2、および Prime31 の Android IAB プラグイン 2.9 を使用しています。アプリをコンパイルしてデバイスで実行すると、adb ログに次のように表示されます。

I/Unity   (18149): AndroidJavaException: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.-----.----/com.facebook.unity.FBUnityLoginActivity}; have you declared this activity in your AndroidManifest.xml?

ただし、Assets/Plugins/Android/AndroidManifest.xml ファイルには、次の定義があります。

<activity android:configChanges="locale|fontScale|keyboard|keyboardHidden|mcc|mnc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|touchscreen|uiMode" android:label="@string/app_name" android:launchMode="singleTask" android:name="com.unity3d.player.UnityPlayerActivity" android:screenOrientation="sensorLandscape">

        <category android:name="android.intent.category.LAUNCHER"/>
        <category android:name="android.intent.category.LEANBACK_LAUNCHER"/>
    </intent-filter>
    <meta-data android:name="unityplayer.UnityActivity" android:value="true"/>
</activity>

私には意味がありません。これは以前は機能していましたが、なぜ機能しなくなったのかわかりません。
