android-support-v7-appcompatを使用してアンドロイドアプリを開発しました。 Eclipseとうまくいきました。今日私はSDKを利用できる最新のバージョンに更新しました。すべて正常に動作しますが、アプリケーションの起動時にこのエラーが発生します。私のsdkを更新した後、android.view.InflateExceptionでアプリがクラッシュする：バイナリXMLファイルの行＃36：クラスを膨張させるエラー。android.support.v7.widget.Toolbar

でこのエラーを修正する方法を教えてください、ありがとう
HomeActivity.javaにすぎ – USKMobility
を追加してくださいあまりにも – USKMobility
をactivity_home.xmlファイルを追加してくださいすでにactivity_home.xmlとtoolbar.xml.thanks – cwgi
