I am trying to build a messenger type app. And for this, I have uploaded an image from my phone to Firebase. The image is successfully stored in Firebase storage. I am trying to show the image on my phone. And I use both Picasso and Glide to retrieve the image from Firebase. But my picture isn't showing. But when I add placeholder I can see the default image that is set by a placeholder. How can I solve this problem? My code is given below:

By this line final String downloadUrl = taskSnapshot.getMetadata().getReference().getDownloadUrl().toString(); ur not getting correct downloadeble url of image, so use filePath.getDownloadUrl()

Example

filePath.putFile(ImageUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
    @Override
    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
        filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
            @Override
            public void onSuccess(Uri uri) {
                final String downloadUrl = uri;
                        RootRef.child("Users").child(currentUserId).child("image").setValue(downloadUrl).addOnCompleteListener(new OnCompleteListener<Void>() {
                            @Override
                            public void onComplete(@NonNull Task<Void> task) {
                                if(task.isSuccessful()){
                                    Toast.makeText(getApplicationContext(),"Image save in Database Successfully...",Toast.LENGTH_SHORT).show();
                                    loadingBar.dismiss();
                                }
                                else{
                                    String message = task.getException().toString();
                                    Toast.makeText(getApplicationContext(),"Error:"+message,Toast.LENGTH_SHORT).show();
                                    loadingBar.dismiss();
                                }
                            }
                        });
            }
        });
    }
});

or use continueWithTask

//add file on Firebase and got Download Link
filePath.putFile(imageUri).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();
        }
        return filePath.getDownloadUrl();
    }
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
    @Override
    public void onComplete(@NonNull Task<Uri> task) {
        if (task.isSuccessful()){
            Uri downUri = task.getResult();
            Log.d(TAG, "onComplete: Url: "+ downUri.toString());
        }
    }
});
