inflating class fragment が出てしまう｡
以下の様なfragmentを2つ並べたようなViewを作ったのですが､ActivityのsetContentViewで以下のエラーが出てしまいます｡
activity_video_player.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="wrap_content"

android:id="@+id/video_info_fragment"
android:layout_width="wrap_content"
android:layout_height="wrap_content">

</LinearLayout>

ちなみに､このVideoInfoFragmentを追加する以前はエラーは出ませんでした｡
あと関係があるのかわからないのですが､AndroidManifestでNoActionBarを指定しています｡
このエラーについて､検索し､様々な方法を試しましたが結局､直りませんでした｡
どなたか解決方法がわかる方､教えて頂ければ幸いです｡
よろしくお願いします｡
