error: cannot find symbol method getDownloadUrl()

error: cannot find symbol method getDownloadUrl() - java

I'm still a beginner in programming. I'm developing an application for a college job. However, I came across this mistake. I do not know how I can fix it. This problem:
error: cannot find symbol method getDownloadUrl()
How can I solve this error?
Here is my code:

try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uriProfileImage);
imageView.setImageBitmap(bitmap);
uploadImageToFirebaseStorage();
} catch (IOException e) {
e.printStackTrace();
}
}
}
private void uploadImageToFirebaseStorage() {
StorageReference profileImageRef =
FirebaseStorage.getInstance().getReference("profilepics/" + System.currentTimeMillis() + ".jpg");
if (uriProfileImage != null) {
progressBar.setVisibility(View.VISIBLE);
profileImageRef.putFile(uriProfileImage)

*
This method worked for me.
profileImageRef.putFile(uriProfileImage).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {

Try this!

Cannot retrieve images from firebase

I stored texts and images in firebase Storage, here's how my images path looks like in storage (1655329886202.jpg),
and here's ow they look in realtime database (https://firebasestorage.googleapis.com/v0/b/link-plus-8e35e.appspot.com/etc...)
I retrieved the texts but can't retrieve the images to the recycler view, I'm new to programming.
here is the code.
adapter :
public class ImageViewHolder extends RecyclerView.ViewHolder {
public TextView textViewName;

super(itemView);

I cannot seem to log in into my main activity

I cannot log in to my application, and I found no error in the codes. It keeps showing, email is required every time I tried to log in. I connect this app with FireStore as well. So, I need help what did I did wrong here because it supposed to go to the main activity after my login page:
public class Login extends AppCompatActivity {

return;
}
if (TextUtils.isEmpty(password)) {

return;
}
if(password.length() < 6) {
mPassword.setError("6 or more character long");
return;

Call adapter.notifyItemChanged(position); working so weird

I have a list that I get from firebase, this list is about posts and what I need is when user like it or unlike it, the list updated through adapter. as I used recyclerview and adapter to show my data after receiving it from firebase. Actually, everything works so fine with me but just this issue when user like or unlike the post it goes crazy. I tried to make a toast to make sure that I'm working with the same position as I expected and it proved me right.
the photo of the post appears and disappears by clicking like button like the vides shows and it does not updating the data in a proper way like it mess with the number of likes
You can find my code below with a video to illustrate the problem I am facing.
I hope somebody can help me out.

Android Firebase java.lang.StackOverflowError: stack size 8MB error when user is uploading an image

Hello I'm trying to create a profile screen where the user can upload their own profile image and change the ImageView into something that they've uploaded. But upon using this Upload profile image for a user Firebase as a reference I encountered an error when I'm starting to upload the images to the database.
My Code
public class userMain extends Fragment {
private TextView userfirstName,usersecondName,userNumber,userGender,userEmail,userDate;

userfirstName = (TextView) view.findViewById(R.id.firstnametv);
usersecondName = (TextView) view.findViewById(R.id.secondnametv);
userNumber = (TextView) view.findViewById(R.id.numbertv);
userGender = (TextView) view.findViewById(R.id.gendertv);
userEmail = (TextView) view.findViewById(R.id.emailtv);
userDate = (TextView) view.findViewById(R.id.datetv);
FirebaseUser user= FirebaseAuth.getInstance().getCurrentUser();
storage = FirebaseStorage.getInstance();
storageReference = storage.getReference();
String useruid=user.getUid();
DatabaseReference ref = FirebaseDatabase.getInstance().getReference().child("Accounts").child("Users").child(useruid);
imageView.setOnClickListener(new View.OnClickListener() {

Change this:
StorageReference filepath= storageReference.child("Images").child(filePath.getLastPathSegment());
filepath.putFile(filePath).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Uri downloadUrl = taskSnapshot.getDownloadUrl();
img.child("image").setValue(downloadUrl);
}
to this:
StorageReference filepath= storageReference.child("Images").child(filePath.getLastPathSegment());
filepath.putFile(filePath).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
String downloadUrl = taskSnapshot.getDownloadUrl().toString()
img.child("image").setValue(downloadUrl);
}
saving the downloadUrl as string in your firebase database
