In all of theses pages, I have a YouTubePlayer with a different id [video](https://www.mindstick.com/articles/290133/6-necessary-preparations-you-need-before-editing-a-video).The [problem](https://yourviews.mindstick.com/view/81399/tackling-the-problem-of-unemployment-during-corona-pandemic) is that all the YouTubePlayer [component](https://www.mindstick.com/articles/12262/learn-how-to-make-a-component-in-magento-2) has the same video at the same time.\ \ **Concretely :**When the first [page](https://www.mindstick.com/articles/13031/why-to-make-a-wikipedia-page) is displayed, the YouTubePlayer show the first video, so all seems to be ok.

So on the 3rd page the 3rd id video is set to the YouTubePlayer component. At that moment the 2nd page currently displayed [switch](https://www.mindstick.com/blog/104495/switch-bringing-new-advancements-in-the-education-management-system) automatically to the 3rd video.\ \ It was like if the [instance](https://www.mindstick.com/forum/155658/testing-connection-to-cloud-sql-instance-with-a-mysql-client-from-vm-instance) of YouTubePlayer was single for all the pages. But on each page new FragmentYouTubePlayer() is correctly called.\ I don't understand where is the problem. Finally, I [wonder](https://yourviews.mindstick.com/story/2441/wheatgrass-juice-wonder-for-your-health) if it's possible to use severals YouTubePlayer component (in a viewpager) at the same time or not ? ## Replies ### Reply by Anonymous User YouTubePlayer follows the Singleton pattern controlling all the different YouTubePlayerView instances. \ Just out of curiouslty i have implelemented a sample for this and it worked for me, so my code may help you analyze your problem\ In my main activity, using PagerAdapter : ``` private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {    public ScreenSlidePagerAdapter(android.support.v4.app.FragmentManager fm) {        super(fm);    }    @Override    public android.support.v4.app.Fragment getItem(int position) {        fragmentYouTubeContent = FragmentYouTubeContent.create(position);        return fragmentYouTubeContent;    }    @Override    public int getCount() {        int nb = 3;        return nb;    }}My FragmentYouTubeContent.classpackage com.orange.OrangeJobs; ``` \ \ import java.util.List; ``` import com.google.android.youtube.player.YouTubeInitializationResult;import com.google.android.youtube.player.YouTubeStandalonePlayer;import com.google.android.youtube.player.YouTubeThumbnailLoader;import com.google.android.youtube.player.YouTubeThumbnailView;import android.support.v4.app.Fragment;import android.annotation.SuppressLint;import android.app.Dialog;import android.content.Intent;import android.content.pm.ResolveInfo;import android.content.res.Configuration;import android.os.Bundle;import android.util.Log;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.widget.FrameLayout;import android.widget.TextView;import android.widget.Toast;public class FragmentYouTubeContent extends Fragment implements YouTubeThumbnailView.OnInitializedListener {      public static final int REQ_START_STANDALONE_PLAYER = 101;      private static final int REQ_RESOLVE_SERVICE_MISSING = 2;      private static final int RECOVERY_DIALOG_REQUEST = 1;    /**     * The fragment's page number.     */    private int mPageNumber;    private String urlYouTube;    private boolean canHideStatusBar = false;    private Dialog errorDialog;    FrameLayout rl;    private YouTubeThumbnailView thumbnailView;    /**     * Factory method for this fragment class.
