Fragment
下位互換性パッケージを使用して、を含むレイアウトを拡張しようとしています。jarファイルを取得して、プロジェクトのlibsフォルダーに配置しました。Fragmentを拡張し、ActivityのcontentViewをに設定してFragmentを膨らませようとしました
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<fragment
class="com.test.fragments.AdFragment"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/></LinearLayout>
しかし、コンテンツビューを設定するClassNotFoundException
と、フラグメントタグのが失敗します。これがlogcatの出力です。
