Error YouTubePlayerView XML

I'm trying to put a YouTubePlayerView inside my Adapter but I didn't have success.

I don't want to call a new Intent. I want to show the video inside my app.

I put the YouTubeAndroidPlayerApi.jar inside my folder libs and look at the project properties and it's all ok (I followed this tutorial)

Here's is my XML code and the log.

<LinearLayout        android:id="@+id/ll_contentExercicios_LayoutVideoGif"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal"><com.google.android.youtube.player.YouTubePlayerView             android:id="@+id/vv_contentExercicios_YoutubeVideo"            android:layout_width="300dp"            android:layout_height="150dp" /><ImageView            android:id="@+id/iv_contentExercicios_GifExercicio"            android:layout_width="100dp"            android:layout_height="150dp"            android:layout_marginLeft="30dp"></ImageView></LinearLayout>

P.S.: I was reading the Youtube API documentation and it said that it is necessary an activity extends a YouTubeBaseActivity to use an YouTubePlayerView so I know I will need some way to create the YouTubePlayerView inside my BaseAdapter.

Thanks and regards.
