念の為、画像では以下の通り。
エラーの解決方法を示していく。
１．「GooglePlayGames」と「PlayServicesResolver」の削除する
[Project] タブ内の「GooglePlayGames」と「PlayServicesResolver」を削除する。
２．「GooglePlayGamesPlugin-0.9.50.unitypackage」を再度インポートする
インポートの方法についはTapTapTap!!!（１６）～Google Play Services がインポートできない～で記載しているため省略する。
３．原因
「GooglePlayGamesPlugin-0.9.50.unitypackage」インポート時に[Project]タグ内に[Plugins] > [Android] のフォルダがなかったことが原因。エラーログにもしっかり書いてあったので、エラーはよく読みましょうということで一つ。
