Android Emulator：このアプリはGoogle Play開発者サービスなしでは動作しません

Android 4.2.2以降、AndroidエミュレータでGoogleサービスを実行できます。現在、Android Google+のサインインとサインアウトを機能させることができるかどうかを確認するためのテストプロジェクトを作成しました。

次のチュートリアルに従いました： http://www.androidhive.info/2014/02/Android-login-with-google-plus-account-1/

次のチュートリアル/サイトから使用される追加情報を使用します。

これにより、次のコードが生成されました。

私がやった他の手順は次のとおりです。

https://console.developers.google.com/project でプロジェクトを作成しました：

Google+ API：

Google+ API on

そして、正しいSHA1とプロジェクトとまったく同じ名前空間で作成されたクライアントID：

And a Client ID created with the correct SHA1

Eclipseで：

Google-play-servicesライブラリをインストールしました：

Google-play services installed

そして、プロジェクトに追加しました：

Google-play services library added (2)Google-play services library added (2)

また、バージョン4.4.2でエミュレーターを作成しました。

I've also created an Emulator with version 4.4.2

しかし、アプリを実行すると次のエラーが発生し、ボタンをクリックするとこのエラーが表示され続けます。

どこに問題があるのか​​誰にもわかりますか？回答ありがとうございます。

OK.

Android 4.4.2をプロジェクトビルドターゲットおよびエミュレータターゲットとして使用する代わりに、Google API 4.4.2を選択しました。GooglePlayサービスのエラーは表示されなくなりました。

ただし、NullPointerExceptionが発生しますが、少なくとも続行できます。;）

編集：NullPointerExceptionを修正し、元の投稿のコードを変更しました。すべて正常に動作するので、この投稿が、Android Emulator。

通常のAPIレベル19ではなく、エミュレーターターゲットとしてGoogle API APIレベル19を使用してみてください。
