Eclipseに「App Engine Connected Android Project」を作成できません：「要素の作成に失敗しました」

Question

Eclipseのウィザードで「App Engine Connected Android Project」を作成できません。 「完了」ボタンをクリックすると、次のエラーメッセージが表示されます。

要素の作成に失敗しました。

com.android.ide.eclipse.adt.internal.project.AndroidNature.setupProjectNatures（Lorg /日食/コア/リソース/さらにiProject; Lorg /日食/コア/ランタイム/ IProgressMonitor;）V

私が使用します。

• のWindows 7（x64）の
• Eclipseのジュノ4.2
• jre7
• Google App EngineのSDK 1.8.0。
• のAndroid SDKのAPI 8と17

それは新規インストールです。 Eclipseを新規にインストールする前に、それはうまくいった。私はまた、 "プロジェクト番号"と "APIキー"の正しい値を挿入しました。

ウィザードは唯一以下の内容で ".project" という名前のファイルを作成します。

<?xml version="1.0" encoding="UTF-8"?> 
<projectDescription> 
    <name>Test</name> 
    <comment></comment> 
    <projects> 
    </projects> 
    <buildSpec> 
    </buildSpec> 
    <natures> 
    </natures> 
</projectDescription>

Answer 1

私が持っています同じ問題もある。私はアンドロイドSDKを更新しました。その時点から、「Rは解決できません」というエラーが発生したため、プロジェクトをコンパイルできなくなりました。私は新しい接続されたプロジェクトを作成しようとしましたが、私たちがこのスレッドで話しているエラーを受け取ります。

@Gargamel：私はエラーを取得し、ウィザードを使用して新規のAndroidプロジェクトを作成する場合は、「Rは解決できません」

私はこのプロジェクトを20日以内に実施する必要があり、もはや動作しません。
