How to autoplay video through YouTube Player

I am developing an app in which I have shown YouTube videos thumbnails in RecyclerView and there is YouTube Player fragment on top which plays the user selected video. I succeed in doing so. but the problem is that I want to auto play the user selected video.
below is my code:
main_activity.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="2"
android:orientation="vertical"
tools:context="com.example.pc.fkidshell.Main2Activity">
<fragment
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/VideoFragment"
android:name="com.google.android.youtube.player.YouTubePlayerFragment"
android:layout_below="#+id/my_thirdtoolbar"/>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/VideoList"
android:layout_below="#+id/VideoFragment"
android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>
</RelativeLayout>
secvideo_row.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/thumbnailView"
android:layout_gravity="center_horizontal"/>
</LinearLayout>
Main_Activity.java:
public class Main2Activity extends AppCompatActivity implements YouTubeThumbnailView.OnInitializedListener, YouTubeThumbnailLoader.OnThumbnailLoadedListener, YouTubePlayer.OnInitializedListener {
YouTubePlayerFragment playerFragment;
YouTubePlayer Player;
YouTubeThumbnailView thumbnailView;
YouTubeThumbnailLoader thumbnailLoader;
RecyclerView VideoList;
RecyclerView.Adapter adapter;
List<Drawable> thumbnailViews;
List<String> VideoId;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
thumbnailViews = new ArrayList<>();
VideoList = (RecyclerView) findViewById(R.id.VideoList);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this);
VideoList.setLayoutManager(layoutManager);

VideoList.setAdapter(adapter);
VideoId = new ArrayList<>();
thumbnailView = new YouTubeThumbnailView(this);
thumbnailView.initialize("AIzaSyAXlMCst9tNrTGz4xAZ0mY6mJlkNU-3DAs", this);
playerFragment = (YouTubePlayerFragment) getFragmentManager().findFragmentById(R.id.VideoFragment);
playerFragment.initialize("AIzaSyAXlMCst9tNrTGz4xAZ0mY6mJlkNU-3DAs", this);
}
#Override
public void onInitializationSuccess(YouTubeThumbnailView youTubeThumbnailView, YouTubeThumbnailLoader youTubeThumbnailLoader) {

}
}
#Override

View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.secvideo_row, parent, false);
return new MyView(itemView);
}
#Override
public void onBindViewHolder(VideoListAdapter.MyView holder, final int position) {
holder.imageView.setImageDrawable(thumbnailViews.get(position));
holder.imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Player.loadVideo(VideoId.get(position));
//Player.loadVideo(VideoId.get(position));
}
});
}
#Override
public int getItemCount() {
return thumbnailViews.size();
}
}
}

When the Youtube player is initialized, set a player state change listener so that you can play the video when the video is loaded and make sure your activity implements player state callbacks.
Detailed code :
#Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
Player = youTubePlayer;
Player.setOnFullscreenListener(new YouTubePlayer.OnFullscreenListener() {
#Override
public void onFullscreen(boolean b) {
VideoList.setVisibility(b ? View.GONE : View.VISIBLE);
}
});
Player.setPlayerStateChangeListener(this); //set player state change listener
}
#Override
public void onAdStarted() {
}
#Override
public void onLoaded(String videoId) {
if(!TextUtils.isEmpty(videoId) && Player != null)
Player.play(); //auto play
}
#Override
public void onLoading() {
}
#Override
public void onVideoEnded() {
}
#Override
public void onVideoStarted() {
}
#Override
public void onError(ErrorReason reason) {
Log.e("onError", "onError : " + reason.name());
}

i hade the same problem, i use YouTubePlayerFragment though and this is what i did.
public async void PlayVideo(params string[] videoId)
{
if (YoutubePlayer != null && videoId != null && videoId.Length > 0)
{
YoutubePlayer.CueVideos(videoId);
await Task.Delay(TimeSpan.FromSeconds(5)); // whait untill the files load.
YoutubePlayer.Play();
}
}
and the player get assigned here
public void OnInitializationSuccess(IYouTubePlayerProvider provider, IYouTubePlayer player, bool wasRestored)
{
if (!wasRestored)
{
YoutubePlayer = player;
PlayVideo(elemnt.VideoSource.ToArray());
}
}

Video is not playing in YoutubePlayer Fragment

I am making an app which uses Youtube player fragment. It is loaded but video is not getting played. Here is my code:
Youtube.java (Fragment)
public class Youtube extends YouTubePlayerFragment {
public Youtube() {
}
public static Youtube newInstance(String url) {
Youtube frag = new Youtube();
Bundle b = new Bundle();
b.putString("url", url);
frag.setArguments(b);
frag.init();
return frag;
}
private void init() {
initialize(API_KEY, new YouTubePlayer.OnInitializedListener() {
#Override
public void onInitializationFailure(YouTubePlayer.Provider arg0, YouTubeInitializationResult arg1) {
}
#Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
if (!wasRestored) {
player.cueVideo(getArguments().getString("url"));
// player.play();
}
}
});
}
}
Activity:
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.activity_main);
Youtube f = Youtube.newInstance("https://www.youtube.com/watch?v=o49aHgzTOGw");
FragmentManager fragmentManager=getFragmentManager();
fragmentManager.beginTransaction().add(f,"Fragment").commit();
}
Layout:
<FrameLayout>
<fragment class="com.google.android.youtube.player.YouTubePlayerFragment"
android:id="#+id/Fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</FrameLayout>
Where I am going wrong. I am not able to figure it out. Do I need to extend YoutubeBaseActivity? How to achieve this?

I think you should write the code in official way. Take look at here, and download the zip file(sample applications included in the YouTubeAndroidAPIDemo package) here to get the sample. And take look at FragmentDemoActivity.
Basically, you need to do the Activity which include YoutubePlayerFragment as follows:
public class FragmentDemoActivity extends YouTubeFailureRecoveryActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragments_demo);
YouTubePlayerFragment youTubePlayerFragment =
(YouTubePlayerFragment) getFragmentManager().findFragmentById(R.id.youtube_fragment);
youTubePlayerFragment.initialize(DeveloperKey.DEVELOPER_KEY, this);
}
#Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,
boolean wasRestored) {
if (!wasRestored) {
player.cueVideo("nCgQDjiotG0");
}
}
#Override
protected YouTubePlayer.Provider getYouTubePlayerProvider() {
return (YouTubePlayerFragment) getFragmentManager().findFragmentById(R.id.youtube_fragment);
}
}
YouTubeFailureRecoveryActivity :
public abstract class YouTubeFailureRecoveryActivity extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener {
private static final int RECOVERY_DIALOG_REQUEST = 1;
#Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
YouTubeInitializationResult errorReason) {
if (errorReason.isUserRecoverableError()) {
errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
} else {
String errorMessage = String.format(getString(R.string.error_player), errorReason.toString());
Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == RECOVERY_DIALOG_REQUEST) {
// Retry initialization if user performed a recovery action
getYouTubePlayerProvider().initialize(DeveloperKey.DEVELOPER_KEY, this);
}
}
protected abstract YouTubePlayer.Provider getYouTubePlayerProvider();
}
And the fragments_demo.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<fragment
android:name="com.google.android.youtube.player.YouTubePlayerFragment"
android:id="#+id/youtube_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>

Video is playing for a millisecond implemented using youtubeplayer view

I am trying to implement to play youtube video in my app using youtubeplayer view when user clicks on button but its just playing for a millisecond,after that it just stop.App is not crashing but video is also not playing.
Code for the same is-

//videoId=getIntent().getExtras().getString("url");
}

public void onInitializationFailure(Provider provider, YouTubeInitializationResult result) {
Toast.makeText(this, "Failured to Initialize!", Toast.LENGTH_LONG).show();
}
#Override

trouble with running YoutubeAndroidAPIDemo app

I checked stackoverflow for similiar problems and didn't found anything.
so here's my problem, I'm building an android app and I need to use YouTube API.
I followed this guide:
https://developers.google.com/youtube/android/player/
but I can't seem to run the Demo App.
the entire project is full of errors and I can't understand why,
all of the "R.id.blabla" items are having an error saying:
"blabla cannot be resolved or is not a field"
I checked those Questions - Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties
and : YouTubeAndroidAPIDemo does not run
tried everything there, didn't helped much.
I'm pretty sure I am missing something but I have no idea what.
anyone else encountered something like this before?
plz help :D

I had a similar problem, try deleting the: import R.java line, if it's there.
