クラスAndroid.support.v7.widget.SearchViewをインスタンス化できません

誰か助けてください！プロジェクトにappcompat検索ビューを追加しようとしています。失敗しました。 Android.support.v7.widget.SearchViewをSearchView（API> 10）に変更すると、すべて問題ありません。

これは私のメニュー解像度です：

<item Android:id="@+id/action_search"
    Android:title="@string/search_view_title"
    Android:icon="@drawable/action_search"
    sabd:showAsAction="always|collapseActionView"
    sabd:actionViewClass="Android.support.v7.widget.SearchView" />

これが私がSeachViewを使おうとする方法です：

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        inflater.inflate(R.menu.teach, menu);
        mSearchItem = menu.findItem(R.id.action_search);
        mSearchItem.setVisible(true);
        mSearchView = (SearchView) MenuItemCompat.getActionView(mSearchItem);
        mSearchView.setQueryHint(getString(R.string.search_view_hint));
        mSearchView.setOnQueryTextListener(this);
    }

これは私のマニフェストファイルです：

問題は悪いv7サポートライブラリにありました。すべてを正常に更新した後。

おそらくリリースビルドに表示されたものと似ていますが、v21サポートライブラリに切り替えたときにデバッグビルドには表示されませんでした。難読化の問題であることが判明し、この行をproguard-rules.txtファイルに追加すると修正されました。

-keep class Android.support.v7.widget.SearchView { *; }

Android StudioとGradleを使用してプロジェクトをビルドしたときにも同じ問題が発生しました。v7互換のSearchViewを追加したいと思います。

解決策は、gradleプラグインのバージョンを0.9.1などから0.9.0に変更することです。それは私が見つけた一時的な方法です。それはおそらくgradleプラグインのバグです。お役に立てば幸いです。

    dependencies {
        classpath "com.Android.tools.build:gradle:0.9.0"
    }
