Panorama Solution for a Camera Application

Is there a panorama open-source solution for the Android camera app?
I came across these options:
panoramagl-android
WideAnglePanoramaModule.java
but they look a little old and have no support, is there anything newer?
I also came across this page:
But there is not much documentation about it that I could find.
I would like to get a full solution including capturing the images, stitching and displaying.

Look at this article:
https://itnext.io/android-360-panorama-cedbfb47a9e
The thing that i dont like is that all images are from assets. I did it with image from firebase:
add dependancy:
dependencies {
/*
* Google VR SDK
* Release version: https://github.com/googlevr/gvr-android-sdk/releases
* */
implementation 'com.google.vr:sdk-panowidget:1.180.0'
implementation 'com.github.silvestrpredko:dot-progress-bar:1.1'
}
add class
public class SimpleVrPanoramaActivity extends Activity {
#BindView(R.id.progressBar2)
DotProgressBar dotProgressBar;
#BindView(R.id.pano_view)
VrPanoramaView panoWidgetView;
private String bar_panorama1;
private String mPost_key = null;
private Bitmap[] bitmaps = new Bitmap[1];
private DatabaseReference databaseReference;
private VrPanoramaView.Options panoOptions = new VrPanoramaView.Options();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_panorama);
ButterKnife.bind(this);
if (getIntent().getExtras() != null) {
mPost_key = getIntent().getExtras().getString("bar_id");
}
panoOptions.inputType = VrPanoramaView.Options.TYPE_MONO;
databaseReference = FirebaseDatabase.getInstance().getReference().child("bars").child(mPost_key).child("pano");
fetchPanorama();
}
private void fetchPanorama() {
databaseReference.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(#NonNull DataSnapshot dataSnapshot) {
bar_panorama1 = dataSnapshot.child("i1").getValue(String.class);
glideImage(bar_panorama1);
}
#Override
public void onCancelled(#NonNull DatabaseError databaseError) {
Toast.makeText(SimpleVrPanoramaActivity.this, "Проверьте подключение к интернету!", Toast.LENGTH_LONG).show();
}
});
}
public void glideImage(String bar_panorama) {
Glide.with(SimpleVrPanoramaActivity.this)
.asBitmap()
.load(bar_panorama)
.into(new CustomTarget<Bitmap>() {
#Override
public void onLoadFailed(#Nullable Drawable errorDrawable) {
dotProgressBar.setVisibility(View.GONE);
}
#Override
public void onResourceReady(#NonNull Bitmap resource, #Nullable Transition<? super Bitmap> transition) {
bitmaps[0] = resource;
panoWidgetView.loadImageFromBitmap(bitmaps[0], panoOptions);
dotProgressBar.setVisibility(View.GONE);
}
#Override
public void onLoadCleared(#Nullable Drawable placeholder) {
}
});
}
#Override
protected void onPause() {
panoWidgetView.pauseRendering();
super.onPause();
}
#Override
protected void onResume() {
super.onResume();
panoWidgetView.resumeRendering();
}
#Override
protected void onDestroy() {
// Destroy the widget and free memory.
panoWidgetView.shutdown();
super.onDestroy();
}
}

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;
}
}

As you can see, button is binded by Butterknife framework, but I don't know what causes it...

UPDATE 2
LOGINVIEW INTERFACE
public interface LoginView {
void enableInputs();
void disableInputs();
void showProgress();
void hideProgress();
void handleSignUp();
void handleSignIn();
void navigateToMainScreen();
void loginError(String error);
void newUserSuccess();
void newUserError(String error);
}

First, here is one of my answers I shared to setup ButterKnife correctly.
Consider this possible issue:
What are you Overriding here?
#Override //this line here
#OnClick(R.id.signUp)
public void handleSignUp() {
loginPresenter.registerNewUser(inputEmail.getText().toString(),
inputPassword.getText().toString());
}
#Override //this line here
#OnClick(R.id.signIn)
public void handleSignIn() {
loginPresenter.validateLogin(inputEmail.getText().toString(),
inputPassword.getText().toString());
}
Try this instead without the overrides:
#OnClick(R.id.signUp)
public void handleSignUp() {
loginPresenter.registerNewUser(inputEmail.getText().toString(),
inputPassword.getText().toString());
}
#OnClick(R.id.signIn)
public void handleSignIn() {
loginPresenter.validateLogin(inputEmail.getText().toString(),
inputPassword.getText().toString());
}
Then clean your project and run again!
I hope this helps!

I'm referring to the tutorial at ButterKnife tutorial. I think instead of using #BindView it should be #Bind
#Bind(R.id.button)
Button button;
#Bind(R.id.textView)
TextView textView;
#Bind(R.id.radioButton)
RadioButton radioButton;
#Bind(R.id.checkBox)

SwipeRefreshLayout got error and cannot refresh (load more) in the first time

And when I swipe in the second time: it load double data.
This is ChatActivity, what implement that method:
public class ChatActivity extends AppCompatActivity implements View.OnClickListener, SwipeRefreshLayout.OnRefreshListener {
private static EditText txt_chat;
private String registId;
private String chatTitle;
private MessageSender mgsSender;
private int userId;
private DatabaseHelper databaseHelper;
private TimeUtil timeUtil;
private MessageAdapter messageAdapter;
private int offsetNumber = 5;
private SwipeRefreshLayout swipeRefreshLayout;
#Override

setContentView(R.layout.activity_chat);

setSupportActionBar(toolbar);
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
Button btn_send = (Button) findViewById(R.id.btn_send);
txt_chat = (EditText) findViewById(R.id.txt_chat);
swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeLayout);
swipeRefreshLayout.setOnRefreshListener(this);
ListView lv_message = (ListView) findViewById(R.id.listMessage);
timeUtil = new TimeUtil();
databaseHelper = DatabaseHelper.getInstance(getApplicationContext());
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 {
this.setTitle(chatTitle);
}
registId = bundle.getString("regId");
userId = databaseHelper.getUser(chatTitle).getUserId();
List<Message> messages = databaseHelper.getLastTenMessages(AppConfig.USER_ID, databaseHelper.getUser(chatTitle).getUserId(), 0);
messageAdapter = new MessageAdapter(getApplicationContext(), R.layout.chat_item, (ArrayList<Message>) messages);
LocalBroadcastManager.getInstance(this).registerReceiver(onNotice, new IntentFilter("Msg"));
if (messages.size() > 0) lv_message.setAdapter(messageAdapter);
}
private BroadcastReceiver onNotice = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String message = intent.getStringExtra("message");
try {
Message messageObj = new Message();
messageObj.setMessage(message);
messageObj.setUserId(userId);
messageObj.setSender_id(AppConfig.USER_ID);
messageObj.setExpiresTime(timeUtil.formatDateTime(timeUtil.getCurrentTime()));
messageAdapter.add(messageObj);
} catch (ParseException e) {
e.printStackTrace();
}
messageAdapter.notifyDataSetChanged();
}
};
#Override
public void onBackPressed() {
super.onBackPressed();
finish();
}
#Override

}
private static MessageSenderContent createMegContent(String regId, String title) {
String message = txt_chat.getText().toString();
MessageSenderContent mgsContent = new MessageSenderContent();
mgsContent.addRegId(regId);
mgsContent.createData(title, message);
return mgsContent;
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.btn_send:
String message = txt_chat.getText().toString();
databaseHelper = DatabaseHelper.getInstance(getApplicationContext());
mgsSender = new MessageSender();
new AsyncTask<Void, Void, Void>() {
#Override
protected Void doInBackground(Void... params) {
MessageSenderContent mgsContent = createMegContent(registId, AppConfig.USER_NAME);
mgsSender.sendPost(mgsContent);
return null;
}
}.execute();
databaseHelper.addMessage(message, timeUtil.getCurrentTime(), userId, AppConfig.USER_ID);
txt_chat.setText("");
try {
Message messageObj = new Message();
messageObj.setMessage(message);
messageObj.setUserId(AppConfig.USER_ID);
messageObj.setSender_id(userId);
messageObj.setExpiresTime(timeUtil.formatDateTime(timeUtil.getCurrentTime()));
messageAdapter.add(messageObj);

break;
}
}
#Override
public void onRefresh() {
swipeRefreshLayout.setRefreshing(true);
List<Message> messages = databaseHelper.getLastTenMessages(AppConfig.USER_ID, databaseHelper.getUser(chatTitle).getUserId(), offsetNumber);
messageAdapter.insertToTheFirst(messages);
messageAdapter.notifyDataSetChanged();
offsetNumber += 5;
Log.i("Offset number", offsetNumber + "");
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);
}
