Cannot upload image on FirebaseStorage

I cannot upload the profile image on firebase storage.
I'm getting printed the error from the toast.
Why is this happening? I cannot figure the problem out, I reviewed my code so many times.
What could the problem be and how can I adjust my code in order to make this work?
Thank you in advance to everyone.

});
}
}
}

When a Task fails, it contains an exception that has more information about the failure. Logging that allows you to find out the cause of the problem:
public void onComplete(#NonNull Task<UploadTask.TaskSnapshot> task) {
if(task.isSuccessful()) {
Toast.makeText(ProfiloUtenteActivity.this, "Funziona", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(ProfiloUtenteActivity.this, "Error", Toast.LENGTH_SHORT).show();
Log.e("Upload", "Upload failed", task.getException());
}
}
Once you get the error message, I recommend searching for it was likely somebody has dealt with it before.

Item Doesn't seem to upload to Firebase Realtime Database while using Android [duplicate]

How to use getdownloadurl in recent versions?

Closed 3 years ago.
I am following a series of videos on youtube from the channel CodingInFlow. They are a bit Outdated, 2017 is long time ago. The Video Series is great and I followed up the 4th video no problem, except one deprecated function that was easy enough to resolve. The file uploads to the Firebase Storage, but it doesn't show up in the Real Time Database

My question is, is it my mistake that I missed something (I followed the video exactly, and checked the code on the channel's website), or is it that the functionality shifted and something needs to be added?
The reason I ask is that the app works in the video, including the function that the checks for duplicate uploads, but in my reproduction, that function only works while the picture actually uploads, so there has been some shifting, but I don't even know where to start research, so I'm starting here.

This is how I did mine. This code saves the image to the storage and to the firebase realtime database under the child "profile image" as a link.

elFin = findViewById(R.id.btn_dd);
ProfileImage = findViewById(R.id.profile_imageUp);
UsersRef = FirebaseDatabase.getInstance().getReference().child("DriversInformation").child(currentUserID);
UserProfileImageRef = FirebaseStorage.getInstance().getReference().child("profileimage");
ProfileImage.setOnClickListener(new View.OnClickListener() {
#Override

Intent galleryIntent = new Intent();
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);

startActivityForResult(galleryIntent, Gallery_Pick);
}
});

Thanks in advance.

In UploadBook class change this
if(filePath != null) {
mStorageRef.child(bookid[0]).putFile(filePath).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Task<Uri> downloadUrl = taskSnapshot.getMetadata().getReference().getDownloadUrl();

}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
}
});
}
To This-
final StorageReference ref = mStorageRef.child(bookid[0]);
UploadTask uploadTask = ref.putFile(file);
Task<Uri> urlTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
#Override

You can then upload to firebase with the this code:
final UploadTask uploadTask = bytepath.putBytes(thumb_byte_data);
uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override

throw task.getException();
}
// Continue with the task to get the download URL
return filepath.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
thumb_download_url = task.getResult().toString();
}
}
});
}
}).addOnFailureListener(new OnFailureListener() {
#Override

}
});

You can create bitmap with captured image as below:
Bitmap bitmap = Bitmap.createScaledBitmap(yourimageuri, width, height, true);// the uri you got from onactivityresults
You can also view this thirdparty lib to compress your image Click Here

//declear local variable first
Bitmap bitmap;
Uri imageUri;
//button action to call Image picker method
