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:

My Firebase Data Structure: My Firebase Data Structure
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());
}
}
});
