Tasksnapshot.getdownloadurl() Method Not Working

private void uploadImageToFirebaseStorage() { StorageReference profileImageRef = FirebaseStorage.getInstance().getReference('profilepics/' + System.currentTimeMillis()

Solution 1:

Edit: see this comment on why the approach in this answer doesn't work:

firebaser here This answer is wrong. While it at first may appear to work (since it compiles) the result of getDownloadUrl().toString() is not a download URL, but a string representation of a Task object. For a better answer, see stackoverflow.com/a/55503926 or the sample in the Firebase documentation.

Original answer below...

In Firebase Storage API version 16.0.1, the getDownloadUrl() method using taskSnapshot object has changed. now you can use,

taskSnapshot.getMetadata().getReference().getDownloadUrl().toString()

to get download url from the firebase storage.

Solution 2:

To get imageUrl path from storage use this code:

uploadTask.addOnSuccessListener(newOnSuccessListener<UploadTask.TaskSnapshot>() {
    @OverridepublicvoidonSuccess(UploadTask.TaskSnapshot taskSnapshot) {
        if (taskSnapshot.getMetadata() != null) {
            if (taskSnapshot.getMetadata().getReference() != null) {
                Task<Uri> result = taskSnapshot.getStorage().getDownloadUrl();
                result.addOnSuccessListener(newOnSuccessListener<Uri>() {
                    @OverridepublicvoidonSuccess(Uri uri) {
                        String imageUrl = uri.toString();
                        //createNewPost(imageUrl);
                    }
                });
            }
        }
    }});

that is all 😉

NOTE: Do not forget initialize StorageReference and UploadTask in your uploadFile method.

Solution 3:

Try Using this it will download the image from FireBase storage

FireBase Libraries versions 16.0.1

Task<Uri> result = taskSnapshot.getMetadata().getReference().getDownloadUrl();
result.addOnSuccessListener(newOnSuccessListener<Uri>() {
      @OverridepublicvoidonSuccess(Uri uri) {
             String photoStringLink = uri.toString();
      }
});

I faced the similar error I solved it with this method. Hope it helps

uploadTask.addOnSuccessListener(newOnSuccessListener<UploadTask.TaskSnapshot>() {
            @OverridepublicvoidonSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                Task<Uri> task = taskSnapshot.getMetadata().getReference().getDownloadUrl();
                task.addOnSuccessListener(newOnSuccessListener<Uri>() {
                    @OverridepublicvoidonSuccess(Uri uri) {
                        String photoLink = uri.toString();
                        Map userInfo = newHashMap();
                        userInfo.put("profileImageUrl", photoLink);
                        mUserDatabase.updateChildren(userInfo);
                    }
                });
                finish();
                return;
            }
        });

Solution 5:

 ref.putFile(filePath)
                .addOnSuccessListener(newOnSuccessListener<UploadTask.TaskSnapshot>() {
                    @OverridepublicvoidonSuccess(UploadTask.TaskSnapshot taskSnapshot) {

                        taskSnapshot.getStorage().getDownloadUrl().addOnCompleteListener(newOnCompleteListener<Uri>() {
                            @OverridepublicvoidonComplete(@NonNull Task<Uri> task) {
                                changeProfilePic(String.valueOf(task.getResult()));//gives image or file string url
                            }
                        });

try this code will work for sure
