YouTubePlayer api issue

I play video in MainActivityand video is playig fine. While playing video, if I open the same activity another time and come back to previous MainActivity youtube progressbar keeps turning and nothing happens. I read the documentation and couldn't find anything related this problem. Indeed, the documentation is very old (updated in 2015), and YouTubeAndroidPlayerApi library was updated in 2017. Guide me to right direction.
MainActivity.java
public class MainActivity extends YouTubeBaseActivity
implements YouTubePlayer.OnInitializedListener {
private String YOUTUBE_API_KEY = "api_key";
private YouTubePlayerView youtubePlayerView;
#Override
protected void onCreate(Bundle bundle) {
super.onCreate(bundle);
setContentView(R.layout.activity_main);
youtubePlayerView = findViewById(R.id.youtubePlayer);
youtubePlayerView.initialize(YOUTUBE_API_KEY, this);
}
#Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
Log.w("youtube_activity", "onInitialization success");
youTubePlayer.loadVideo("0KSOMA3QBU0");
}
#Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
Toast.makeText(this, "Initialization failure", Toast.LENGTH_SHORT);
}
public void onClick(View view) {
startActivity(new Intent(this, MainActivity.class));
}
}

Found solution with releasing YouTubePlayer when going to another youtubeplayeractivity. When came back to previous youtubeplayeractivity reninitialized YouTubePlayerView.
public void onClick(View view) {
youTubePlayer.release();
startActivity(new Intent(this, MainActivity.class));
}
#Override
protected void onRestart() {
super.onRestart();
youtubePlayerView.initialize(YOUTUBE_API_KEY, this);
}

YoutubePlayer is not playing video and giving error "Network error (400)

Instead of passing complete URL pass only YouTube VideoID
Instead of this
player.cueVideo("https://youtu.be/CMvxh_uXEUc",1);
Try this
player.cueVideo("CMvxh_uXEUc",1);

Getting Youtube videos using RecyclerView and cardView with Firebase in Android studio

I have been working on an android project in which I have used YouTube API and Firebase as a database, I also used recyclerView in it but my videos from Firebase database are not showing in the application, I have implemented it correctly I guess but there is something wrong with it, please help.
I am using Android Studio
YouTube Firebase Adapter java class:
#Override
protected void onCreate(Bundle bundle) {
super.onCreate(bundle);
setContentView(R.layout.youtube_videos);
YDatabaseReference = FirebaseDatabase.getInstance().getReference().child("youT");
YouRecycler = (RecyclerView)findViewById(R.id.Youtube_recycler);
}
#Override
public void onStart() {
super.onStart();
FirebaseRecyclerAdapter<post2youtube, YoutubeViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<post2youtube, YoutubeViewHolder>(
post2youtube.class,
R.layout.youtube_videos_card,
YoutubeViewHolder.class,
YDatabaseReference
) {
#Override
protected void populateViewHolder(YoutubeViewHolder viewHolder, post2youtube model, int position) {
viewHolder.setYoutube(model.getYoutubing());
}
};
YouRecycler.setAdapter(firebaseRecyclerAdapter);
}
public static class YoutubeViewHolder extends RecyclerViewPager.ViewHolder {
View yView;
public YoutubeViewHolder(View itemView) {
super(itemView);
yView = itemView;
}
public void setYoutube(final String youtubing){
final YouTubePlayerView youPlay = (YouTubePlayerView) yView.findViewById(R.id.youtuber);
youPlay.initialize("SOME KEY",
new YouTubePlayer.OnInitializedListener() {
#Override
public void onInitializationSuccess(YouTubePlayer.Provider provider,
YouTubePlayer youTubePlayer, boolean b) {
youTubePlayer.cueVideo(youtubing);
}
#Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
YouTubeInitializationResult youTubeInitializationResult) {
}
});
}
Getter and setters class :
public class post2youtube {
private String youtubing;
public post2youtube(){
}
public post2youtube(String youtubing) {
this.youtubing = youtubing;
}
public String getYoutubing() {
return youtubing;
}
public void setYoutubing(String youtubing) {
this.youtubing = youtubing;
}
}

btn_send.setOnClickListener(this);
Bundle bundle = getIntent().getExtras();
chatTitle = bundle.getString("titleName");
if (getIntent().getBundleExtra("INFO") != null) {
chatTitle = getIntent().getBundleExtra("INFO").getString("name");
this.setTitle(chatTitle);
} else {

}
registId = bundle.getString("regId");
userId = databaseHelper.getUser(chatTitle).getUserId();
List<Message> messages = databaseHelper.getLastTenMessages(AppConfig.USER_ID, databaseHelper.getUser(chatTitle).getUserId(), 0);

}

swipeRefreshLayout.setRefreshing(false);
}
}
UPDATE ISSUE's REASON
I found the reason of that issue. It due to I force the listview scroll to the bottom when it init with this code :
android:stackFromBottom="true"
I replace that code with this but still have same issue:
lv_message.post(new Runnable() {
#Override
public void run() {
lv_message.setSelection(lv_message.getCount() -1);
}
});

I think the problem is , You are trying to show , dismiss and refresh swipeRefreshLayout inside the same method i.e onRefresh().
Make seperate methods for showing and dismissing dialog and invoke them from the place where they are required as I have done below:
#Override
public void onRefresh() {
// refresh code here.
}
#Override
public void showDialog() {
swipeRef.post(new Runnable() {
#Override
public void run() {
if(swipeRef != null)
swipeRef.setRefreshing(true);
}
});
}
#Override
public void dismissDialog() {
if(swipeRef!=null && swipeRef.isShown() )
swipeRef.setRefreshing(false);
}

Error saving image from camera(cwac camera)

I am trying to implement the cwac camera library for taking picture and storing them. When i tested the code on htc desire hd there were few complications. This is the screenshot of camera preview.
And when I take picture it shows image preview as.
The codes I have for this are as follows.
This is Activity for implementing camera preview fragment.

}
}
#Override

This one is for viewing the image taken. ImagePreviewActivity
public class ImagePreviewActivity extends ActionBarActivity {
static byte[] imageToShow = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (imageToShow == null) {
Toast.makeText(this, R.string.no_image, Toast.LENGTH_LONG).show();
finish();
} else {
ImageView iv = new ImageView(this);
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inPurgeable = true;
opts.inInputShareable = true;
opts.inMutable = false;
opts.inSampleSize = 2;
iv.setScaleType(ImageView.ScaleType.FIT_CENTER);
iv.setImageBitmap(BitmapFactory.decodeByteArray(imageToShow,
0,
imageToShow.length,
opts));
imageToShow = null;
iv.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
setContentView(iv);
}
}
}
And as for the xml layouts I have:
for CameraPrevirewFragment
<LinearLayout 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"
tools:context="com.example.ballard.CWACCamera.Camera$PlaceholderFragment"
android:orientation="vertical"
android:weightSum="4">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="0dip"
android:layout_weight="3">
<FrameLayout
android:id="#+id/camera"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#android:drawable/gallery_thumb"
android:id="#+id/ivGridLines"
android:visibility="gone"/>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1">
<SeekBar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/sbZoomControl"
android:layout_alignParentTop="true"
android:background="#null"
android:layout_toLeftOf="#+id/bFlash"
android:layout_alignBottom="#+id/bFlash"
android:layout_toRightOf="#+id/bGrid"

<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ibCaptureButton"
android:layout_centerVertical="true"

android:background="#null"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Flash"
android:id="#+id/bFlash"
android:layout_alignParentTop="true"

android:layout_alignParentEnd="true" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:id="#+id/bGrid"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</RelativeLayout>
</LinearLayout>
and for the camera activity I have
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:id="#+id/rlHomeLayout"
android:layout_width="match_parent" android:layout_height="match_parent"
tools:context="com.example.ballard.Login.Home" tools:ignore="MergeRootFrame"
>
<include
android:id="#+id/toolbar"
layout="#layout/toolbar"/>
<FrameLayout`enter code here`
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/toolbar">
</FrameLayout>
</RelativeLayout>
I am using v7 toolbar as the actionbar and is as follows(toolbar.xml)
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimaryDark"/>
I tried the demo of the library and is working fine on the same mobile set. Also there seems to be no problem while I was testing it on Nexus 5. I am trying this library for the first time and have no clue for solving this
