The way you're getting the download URL looks fishy. Having any sort of while (!uriTask.isSuccessful()); in your Android code is unlikely to ever give the desired result.
This is how I'd normalize it:
String file = storagePath+ ""+ profilorcover +"_"+ user.getUid();
StorageReference storageReference2 = storageReference.child(file);
storageReference2.putFile(uri).continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
#Override
public Task<Uri> then(#NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {
if (!task.isSuccessful()) {
throw task.getException();
}
// Continue with the task to get the download URL
return ref.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
if (task.isSuccessful()) {
Uri downloadUri = task.getResult();
HashMap<String, Object> results = new HashMap<>();
results.put(profilorcover, downloaduri.toString());
databaseReference.child(user.getUid()).updateChildren(results)
.addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
progressDialog.dismiss();
Toast.makeText(getActivity(), "Mengubah Gambar...", Toast.LENGTH_SHORT).show();
}
}
});
} else {
progressDialog.dismiss();
Toast.makeText(getActivity(), e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
});
This is a pretty direct merge of your code with the flow from the Firebase documentation on getting a download URL after uploading an image.

That problem in the code requestcode == result_ok. That must change like resultcode==result_ok. That's why my problem solved.
#Override
public void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
if (requestCode == RESULT_OK){
requestCode replace wirh resultCode.
if(requestCode == IMAGE_PICK_GALLERY_CODE){
image_uri = data.getData();
uploadprofile(image_uri);
}
if (requestCode == IMAGE_PICK_CAMERA_CODE){
uploadprofile(image_uri);
}
}
super.onActivityResult(requestCode, resultCode, data);
}

Hello, I have problem to upload my image to my firebase storage

I was watching YouTube for the instruction implementing storing image to firebase storage.
But, I got an error with getDownloadUrl() I do not know why, it was given codes from firebase helper.

call getDownloadUrl(), the call is asynchronous and you must subscribe on a success callback to obtain the results:
Ref.putFile(imgUir)
.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Ref.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
#Override

Log.e("downloaduri", downloadPhotoUrl.toString());
Toast.makeText(SellerPage.this, "Uploading Image Successful", Toast.LENGTH_LONG).show();
}
});
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle unsuccessful uploads

public String niceRefLink (String date){

I believe the issue is with this block of code
public String niceRefLink (String date){
StorageReference storageRef = FirebaseStorage.getInstance().getReference();
StorageReference dateRef = storageRef.child("profile_images");
return dateRef.toString();
}}
When the image is attempted to be displayed glide says that it is unable to locate the image this is how my database is looking
I tried to use the method niceRefLink to display the image but I was unsuccessful i have also tried the download_url string i have created but also did not work
HI, i tried the answer you submitted but I am still having issues the image is successfully getting uploaded to the database but it is still not getting displayed when i run the app i am getting the toast upload successful but the image stays as the preview image.
private String mImageUri;
private void getUserInfo(){
mUserDatabase.child("Users").addValueEventListener(new ValueEventListener() {
#Override

Map<String, Object> map = (Map<String, Object>) dataSnapshot.getValue();
if(map.get("image")!=null){

Glide.with(getApplication()).load(mImageUri).into(mDisplayImage);
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
}

This code is, How to get image url and how to display in ImageView.
private void getUserInfo(){
mCustomerDatabase.child("Users").child(current_uid).addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
if(dataSnapshot.exists() && dataSnapshot.getChildrenCount()>0){

Glide.with(getApplication()).load(mProfileImageUrl).into(profileImage);

i want that when the user deactivate his account it will not visible anymore in the all user activity

There are multiple ways to doing this.
When you delete account of user. You should delete all nodes attaching to that user. so that any activity related to user will not be visible to other users.!
if you don't want to remove from database section. you can put another key value with the name of status. if user status is deleted or disable. don't fetch the data of that user in activity.
Hope this will help you to answer your question.
if you've still questions in your mind, you can ask.
For deleting child:
rootRef.child(node).removeValue();
Simple deleting the node.
you can customize it according to your need.

DatabaseReference delete = FirebaseDatabase.getInstance().getReference().child("Node");
delete.setValue(null);
