認識器の目的は定数を定義できません

Question

Googleが提供するアクティビティvoicerecognition.javaを使用して、ユーザーが言語を選択し、ハンドセットに向かって話し、彼らが言ったことを見ることができます。それは私がすべての言語定数を取り出すときに機能しますが、言語オプションを入れるとエラーになります。たとえば は：

• 方法getVoiceDetailsIntent（VoiceRecognition）は
• EXTRA_SUPPORTED_LANGUAGESを解決できないタイプのために未定義であるか、またはEXTRA_LANGUAGE_PREFERENCEを解決できない
• フィールドないか、またはフィールド
• 方法ではありません新しい型のrun（）Runnable（）{}はスーパークラスメソッドをオーバーライドする必要があります

私はSDKやそれ以外のものを更新する必要があるかもしれないと思っていました。すべて最新です。私は、提供されたリンクとまったく同じようにアクティビティをコピーしてから、何が間違っているのか分かりません。

を高く評価している右、プロジェクトを右クリックし、プロパティをクリックして、あなたのプロジェクトはEclipseを使用している場合は、この問題を修正するにはレベル8より低いAPIレベルであることが表示されます。左側のメニューからAndroidを選択し、別のプロジェクトビルドターゲットを選択します。レベル8以上で見つからない場合は、ウィンドウ - > Android SDKマネージャーをクリックしてインストールしてください。 RecognizerIntentのどの機能がさまざまなAPIレベルhereで利用可能であるかを確認できます。
