put 2 YouTube videos in the same activity

I have this Activity (videomedia) and I was able to make it play one of the videos but I don't know how to import the second YouTube video, I have the library imported without problems and with a single video if the app works so far.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_videomedia);

    youTubePlayerView=(YouTubePlayerView)findViewById(R.id.youtube_view);
    youTubePlayerView.initialize(claveYoutube,this);
}

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean fueRestaurado) {
    if (!fueRestaurado){
        youTubePlayer.cueVideo("N9SPr-xvLGc"); //https://www.youtube.com/watch?v=N9SPr-xvLGc



    }

}

@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {


    if (youTubeInitializationResult.isUserRecoverableError()){
        youTubeInitializationResult.getErrorDialog(this, 1).show();
    }else {
        String error = "Error al inicializar Youtube"+youTubeInitializationResult.toString();
        Toast.makeText(getApplication(),error,Toast.LENGTH_LONG).show();

    }
}

protected void onActivityResult(int requestcCode, int resultcode, Intent data){
    if (resultcode==1){
        getYoutubePlayerProvider().initialize(claveYoutube,this);

    }
}

protected YouTubePlayer.Provider getYoutubePlayerProvider(){
    return youTubePlayerView;

}

@Override
public void onPlaying() {

}

@Override
public void onPaused() {

}

@Override
public void onStopped() {

}

@Override
public void onBuffering(boolean b) {

}

@Override
public void onSeekTo(int i) {

}

}

//This is my xml:

xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".videomedia">

first video

<com.google.android.youtube.player.YouTubePlayerView
    android:id="@+id/youtube_view"
    android:layout_width="match_parent"
    android:layout_height="141dp"/>

second video

<com.google.android.youtube.player.
    android:id="@+id/youtube_view2"
    android:layout_width="match_parent"
    android:layout_height="141dp"
    android:layout_alignParentStart="true"
    android:layout_alignParentTop="true"
    android:layout_centerVertical="true"
    android:layout_marginStart="0dp"
    android:layout_marginTop="266dp"/>

The videomedio.java could only be programmed to play the first video, but the second video, how could I do it since that part of the code should repeat the method. When I try to repeat it, the application closes.

So far I only get this:
