Youtube Player video not loading when returning to Fragment

I have set up a YouTubePlayerView which works perfectly but I face a weird problem. When I go to another Fragment and then go back, YouTubePlayerView can't load the video, even if the exact code is executed.
private String currentVideoID "p450mjB3mxc";
private YouTubePlayerView youtubeView;
private void init(View view)
{
youtubeView = view.findViewById(R.id.youtubeView);
new YoutubeHelper(youtubeView,currentVideoID,this);
}
public void setYoutubePlayer(YouTubePlayer youtubePlayerPublic)
{
this.youtubePlayer = youtubePlayerPublic;
youtubePlayer.loadVideo(currentVideoID);
}
YoutubeHelper.class:
public class YoutubeHelper {
public final static String YoutubeAPIKey="MY_API_KEY";
public YouTubePlayer youtubePlayerPublic;
private YouTubePlayerView youTubeView;
public YoutubeHelper(YouTubePlayerView youTubeView, String initialVideo, MainFragment fragment)
{
this.youTubeView = youTubeView;
init(initialVideo,fragment);
}
private void init(String initialVideo,final MainFragment fragment)
{
youTubeView.initialize(YoutubeAPIKey,
new YouTubePlayer.OnInitializedListener() {
#Override
public void onInitializationSuccess(YouTubePlayer.Provider provider,
final YouTubePlayer youTubePlayer, boolean b) {
youTubePlayer.cueVideo(initialVideo);
youtubePlayerPublic = youTubePlayer;
fragment.setYoutubePlayer(youTubePlayer);
}
#Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
YouTubeInitializationResult youTubeInitializationResult) {
Log.d("Youtube Error:", youTubeInitializationResult.toString());
}
});
}
}
I have tried this answer with no success at all.
Any ideas?

I found the solution if anyone facing the same problem. Before leaving the fragment do:
youtubePlayer.pause();
youtubePlayer.release();

Trying to add a youtube video to a ListItem

I am creating a listview in Android. When I click on the item in the listview, it goes to second activity with the Youtubeplayer. But instead of playing the video, a message appears inside the Youtube player saying
An error occurred while initializing the youtube player
public class Main2Activity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
final String[] sublectures = {"Part 1", "Part 2"};
ListAdapter appadapter1 = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, sublectures);
ListView list2 = findViewById(R.id.list2);
list2.setAdapter(appadapter1);
list2.setOnItemClickListener(
new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String lecture = String.valueOf(parent.getItemAtPosition(position));
Intent startintent = new Intent(getApplicationContext(),Main3Activity.class);
startActivity(startintent);
}
});
}}
This is Main3Activity
public class Main3Activity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {
public static final String API_KEY = "AIzaSyBdVOqvu3C-MTnmO0iNOgeKBCSmb9ULrXc";
public static final String VIDEO_ID = "W2TYS_Jvzjc";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main3);
YouTubePlayerView youTubePlayerView = findViewById(R.id.youtubePlayerView);
youTubePlayerView.initialize(API_KEY, this);
}
#Override
public void onInitializationFailure (YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult){
Toast.makeText(this, "Fail to Load", Toast.LENGTH_LONG).show();
}
#Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
if (!wasRestored) {
player.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
player.cueVideo(VIDEO_ID);
}
}
}

Try out this code works for me
import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayerView;
public class VideoActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {
YouTubePlayerView youTubePlayerView;
String API_KEY="AIzaSyB2TtG6UjEtDWfzxHvQCf2DJxkUPfJI1Lc";
private static final int RECOVERY_REQUEST = 1;
String TAG="VideoActivity";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video);
youTubePlayerView=(YouTubePlayerView)findViewById(R.id.youtube);
youTubePlayerView.initialize(API_KEY, this);
}
#Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
Bundle bundle = getIntent().getExtras();
String showVideo = bundle.getString("videoId");
youTubePlayer.cueVideo(showVideo);
}
#Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
if (youTubeInitializationResult.isUserRecoverableError()) {
youTubeInitializationResult.getErrorDialog(this, RECOVERY_REQUEST).show();
} else {
Toast.makeText(this, "Error Intializing Youtube Player", Toast.LENGTH_LONG).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == RECOVERY_REQUEST) {
getYouTubePlayerProvider().initialize(API_KEY, this);
}
}
protected YouTubePlayer.Provider getYouTubePlayerProvider() {
return youTubePlayerView;
}
}

Displaying and playing multiple video using youtube player API

I stumble upon issue playing more than 1 video using youtube API.
I found this article: Playing different youtube videos using Youtube Player API
Problem:
I cant find how it solved by keep more than 1 player on same page.
I'm trying to init 2 player with 2 different video code, but when i
tried to play 1 video, both run, then after 1 second, both stopped.
How can i fix it? Can anyone guide me?
Here's my code:
public class YoutubeTvFragment extends Fragment {
private static final String LOG = "Youtube TV";
private FragmentActivity myContext;
private YouTubePlayer YPlayer, YPlayer2;
private static final String YoutubeDeveloperKey = "";
private static final int RECOVERY_DIALOG_REQUEST = 1;
#Override
public void onAttach(Activity activity) {
if (activity instanceof FragmentActivity) {
myContext = (FragmentActivity) activity;
}
super.onAttach(activity);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, Bundle savedInstanceState) {
// Defines the xml file for the fragment
View rootView = inflater.inflate(R.layout.fragment_tv_youtube, container, false);
YouTubePlayerSupportFragment youTubePlayerSupportFragment = YouTubePlayerSupportFragment.newInstance();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.youtube_fragment, youTubePlayerSupportFragment).commit();
youTubePlayerSupportFragment.initialize(YoutubeDeveloperKey, new OnInitializedListener() {
#Override
public void onInitializationSuccess(YouTubePlayer.Provider arg0, YouTubePlayer youTubePlayer, boolean b) {
if (!b) {
YPlayer = youTubePlayer;
YPlayer.cueVideo("eCdXcZeKgxU");
//YPlayer.setShowFullscreenButton(false);
//YPlayer.pause();
//YPlayer.play();
}
}
#Override
public void onInitializationFailure(YouTubePlayer.Provider arg0, YouTubeInitializationResult arg1) {
// TODO Auto-generated method stub
}
});
YouTubePlayerSupportFragment youTubePlayerSupportFragment2 = YouTubePlayerSupportFragment.newInstance();
FragmentTransaction transaction2 = getChildFragmentManager().beginTransaction();
transaction2.add(R.id.youtube_fragment2, youTubePlayerSupportFragment2).commit();
youTubePlayerSupportFragment2.initialize(YoutubeDeveloperKey, new OnInitializedListener() {
#Override
public void onInitializationSuccess(YouTubePlayer.Provider arg0, YouTubePlayer youTubePlayer, boolean c) {
if (!c) {
YPlayer2 = youTubePlayer;
YPlayer2.cueVideo("jgnGD74BKoA");
//YPlayer2.setShowFullscreenButton(false);
//YPlayer2.pause();
//YPlayer2.play();
}
}
#Override
public void onInitializationFailure(YouTubePlayer.Provider arg0, YouTubeInitializationResult arg1) {
// TODO Auto-generated method stub
}
});
return rootView;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
}

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>

YouTube API Playlists in Fragments?

So I've been trying to put a YouTube playlist into my app for days now, and I can't seem to figure it out. I have been following this tutorial, but the problem is my app is in fragments because of the tab view, like this:
public class FragmentTab2 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Get the view from fragmenttab1.xml
View view = inflater.inflate(R.layout.fragmenttab2, container, false);
}
}
How would I do to have the code below, provided by the tutorial, to work on my fragment?
public class TruitonYouTubeAPIActivity extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener {
private YouTubePlayer YPlayer;
private static final String YoutubeDeveloperKey = "AIzaSyDhEeq_FYAdCzMMSigmMcRwF_nQEhUXS-0";
private static final int RECOVERY_DIALOG_REQUEST = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_you_tube_api);
YouTubePlayerView youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
youTubeView.initialize(YoutubeDeveloperKey, this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.you_tube_api, menu);
return true;
}
#Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
YouTubeInitializationResult errorReason) {
if (errorReason.isUserRecoverableError()) {
errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
} else {
String errorMessage = String.format(
"There was an error initializing the YouTubePlayer",
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(YoutubeDeveloperKey, this);
}
}
protected YouTubePlayer.Provider getYouTubePlayerProvider() {
return (YouTubePlayerView) findViewById(R.id.youtube_view);
}
#Override
public void onInitializationSuccess(Provider provider,
YouTubePlayer player, boolean wasRestored) {
YPlayer = player;
/*
* Now that this variable YPlayer is global you can access it
* throughout the activity, and perform all the player actions like
* play, pause and seeking to a position by code.
*/
if (!wasRestored) {
YPlayer.cueVideo("2zNSgSzhBfM");
}
}
}
Thanks in advance.
