Android studio User registration data NOT get inserted to firebase database

My code above is to insert user registration data into the firebase database. but when I build the app and try to insert some demo data into the database to perform a user registration none of them is being inserted to the firebase. can anyone check my code and find out anything that I have done wrong?

How to retrieve latest entry from the firebase realtime database?

I am trying to take inputs from one user and send the same data to another user. I am not sure what to put as an argument in child so that it refers to the same data and I can retrieve and show the data to another user for approval. I am able to send the image but for the data fields like visitor,mobile and flat not sure what to do.
My code is as follows.

In your Main5Activity, I think:
This:
for(DataSnapshot child: dataSnapshot.getChildren()) {
String post = dataSnapshot.child("visitor").getValue(String.class);
String post1 = dataSnapshot.child("mobile").getValue(String.class);
String post2 = dataSnapshot.child("flat").getValue(String.class);
textView.setText("Mr. "+post+"with mobile number: " + post1+"wants to visit your flat: " + post2);
}
Must be like this:
for(DataSnapshot ds: dataSnapshot.getChildren()) {
String post = ds.child("visitor").getValue(String.class);
String post1 = ds.child("mobile").getValue(String.class);
String post2 = ds.child("flat").getValue(String.class);
textView.setText("Mr. "+post+"with mobile number: " + post1+"wants to visit your flat: " + post2);
}

Item duplicated in RecyclerView after application call onStart

Every time the application is destroyed and opened again, by another mean every time the method "onStart" is called, every new item added two times.
And when I close it and open it again, every new item will be repeated three times , and so on...

I appreciate your help as I can't figure out the problem. Please note that a lot of functions have been removed for readability.

To resolve your issue, clear adap zter while loading new data, so duplicacy can be removed and update new data. This issue occur due to multiple call on Android Lifecycle method in various state like
onResume - Called multiple times. So avoid initalization in here
onStart - is called whenever application is come from background to foreground or visible state
// When adding new data
adapter.addAll(data);
adapter.notifyDataSetChanged();
// when updating data again in onResume or onStart
adapter.clear();// clear old data from list
adapter.addAll(data);
adapter.notifyDataSetChanged();
//Inside adapter
//Adding item
void addAll(List<Data> data){
list.addAll(data);
}
//For clearing list
void clear(){
list.clear();
// To update list automatically add below line
//notifyDataSetChanged();
}

Upload Images to Firebase Storage and have a link in Firebase Database

I am currently working on an Incident Reporting application which allows users to choose and upload images.
I am already successful in posting images to Firebase Storage but I am wondering if it is possible to have a link/url in Firebase Database from which I can click to redirect me to Firebase Storage to see that image.
I want this function so that along with user inputs such as Title, Date, Remarks, the end-user would be able to see the "image" child with the link along with other inputs
I have tried searching StackOverflow and Youtube for answers but most of them are old and seem outdated. There is a command "getDownloadUrl" but i believe it has been deprecated.
This is the code from my class that uploads my image to Firebase Storage
private void uploadImage() {
if (filePath != null) {
final ProgressDialog progressDialog = new ProgressDialog(getActivity());
progressDialog.setTitle("Uploading...");
progressDialog.show();
StorageReference ref = storageReference.child("images/"+ UUID.randomUUID().toString());
ref.putFile(filePath)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
progressDialog.dismiss();
Toast.makeText(getActivity(),"Uploaded", Toast.LENGTH_SHORT).show();
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
progressDialog.dismiss();
Toast.makeText(getActivity(),"Failed"+e.getMessage(), Toast.LENGTH_SHORT).show();
}
})
.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
#Override
public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
double progress = (100.0*taskSnapshot.getBytesTransferred()/taskSnapshot.getTotalByteCount());
progressDialog.setMessage("Uploaded"+(int)progress+"%");
}
});
}
}

Intent intent = new Intent();

Any help or tutorials is greatly appreciated!
Database Inputs (not including image)

For storing the images to your Firebase Storage, you first set a correct reference and just store the image there, very similar to Firebase Database data storing.
To have a link in the Firebase Database, you can just use downloadUri you can get from storage and have it stored in the database.
The code for this looks something like this, you can take an inspiration from this and come up with a code that suits you more:
private void uploadFile(Bitmap bitmap) {
FirebaseStorage storage = FirebaseStorage.getInstance();
final StorageReference storageRef = storage.getReference();
final StorageReference ImagesRef = storageRef.child("images/"+mAu.getCurrentUser().getUid()+".jpg");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 20, baos);
byte[] data = baos.toByteArray();
final UploadTask uploadTask = ImagesRef.putBytes(data);
uploadTask.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
Log.i("whatTheFuck:",exception.toString());
}
}).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#RequiresApi(api = Build.VERSION_CODES.KITKAT)
#Override
public void onSuccess(final UploadTask.TaskSnapshot taskSnapshot) {
// taskSnapshot.getMetadata() contains file metadata such as size, content-type, and download URL.
Task<Uri> urlTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
#Override
public Task<Uri> then(#NonNull Task<UploadTask.TaskSnapshot> task) {
if (!task.isSuccessful()) {
Log.i("problem", task.getException().toString());
}
return ImagesRef.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
DatabaseReference ref = FirebaseDatabase.getInstance().getReference().child("users").child(mAu.getCurrentUser().getUid());
Log.i("seeThisUri", downloadUri.toString());// This is the one you should store
ref.child("imageURL").setValue(downloadUri.toString());
} else {
Log.i("wentWrong","downloadUri failure");
}
}
});
}
});
}

If i understand correctly you can upload images to storage succesfully but you are having trouble when you want to get that image direct url.
Try this code:
StorageReference storageRef=FirebaseStorage.getInstance().getReference().child("images/"+ UUID.randomUUID().toString());
storageRef.putFile(filePath).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
#Override
public void onComplete(#NonNull Task<UploadTask.TaskSnapshot> task) {
if(task.isSuccessful()){
storageRef.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override
public void onSuccess(Uri uri) {
String URL = uri.toString();
//This is your image url do whatever you want with it.
}
});
}
}
});
